A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth , or flows into another body of water , such as a lake or ocean . A basin is separated from adjacent basins by a perimeter, the drainage divide , made up of a succession of elevated features, such as ridges and hills . A basin may consist of smaller basins that merge at river confluences , forming a hierarchical pattern .
112-621: The Clean Water Rule is a 2015 regulation published by the U.S. Environmental Protection Agency (EPA) and the United States Army Corps of Engineers (USACE) to clarify water resource management in the United States under a provision of the Clean Water Act of 1972 . The regulation defined the scope of federal water protection in a more consistent manner, particularly over streams and wetlands which have

The rule provides protection for headwaters that have these features and have a significant connection to downstream waters. Adjacent waters are defined by three qualifying circumstances established by the rule. These can include wetlands, ponds, impoundments, and lakes which can impact the chemical, biological or physical integrity of neighboring waters. All existing exclusions from longstanding agency practices are officially established for
560-456: A case-by-case basis. This contributed to an uptick in lawsuits for the next 8 years challenging the EPA's regulatory authority over streams and wetlands. Seeking to reduce confusion and to restore the original scope of WOTUS to pre-SWANCC levels, repeated unsuccessful attempts were made to pass a bill called the "Clean Water Authority Restoration Act" in each Congress from 2002 to 2010. In April 2011,
672-454: A drainage basin, and there are different ways to interpret that data. In the unlikely event that the gauges are many and evenly distributed over an area of uniform precipitation, using the arithmetic mean method will give good results. In the Thiessen polygon method, the drainage basin is divided into polygons with the rain gauge in the middle of each polygon assumed to be representative for
784-540: A drainage boundary is referred to as watershed delineation . Finding the area and extent of a drainage basin is an important step in many areas of science and engineering. Most of the water that discharges from the basin outlet originated as precipitation falling on the basin. A portion of the water that enters the groundwater system beneath the drainage basin may flow towards the outlet of another drainage basin because groundwater flow directions do not always match those of their overlying drainage network. Measurement of
896-502: A dramatic move to the right, President Ronald Reagan in 1981 appointed Anne Gorsuch as EPA administrator. Gorsuch based her administration of EPA on the New Federalism approach of downsizing federal agencies by delegating their functions and services to the individual states. She believed that EPA was over-regulating business and that the agency was too large and not cost-effective. During her 22 months as agency head, she cut
1008-572: A formal proposed rule on April 21, 2014. On May 27, 2015, after a public comment period and numerous meetings with state entities, public and private stakeholders, then-EPA Administrator Gina McCarthy along with Assistant Army Secretary Jo-Ellen Darcy signed the Clean Water Rule, set to become effective in August of that year. EPA had stated that the 2015 rule created no additional burden for stakeholders working in agriculture since there

Johnson rescinded the draft; in July 2008, he issued a new version which did not state that global warming was danger to public welfare. Burnett resigned in protest. In April 2008, the Union of Concerned Scientists said that more than half of
1680-591: A second term. As a condition for accepting his appointment, Ruckleshaus obtained autonomy from the White House in appointing his senior management team. He then appointed experienced competent professionals to the top management positions, and worked to restore public confidence in the agency. Lee M. Thomas succeeded Ruckelshaus as administrator in 1985. In 1986 Congress passed the Emergency Planning and Community Right-to-Know Act , which authorized
1792-708: A senior official at the Environmental Protection Agency had worked to quash a review of Roundup's main ingredient, glyphosate, that was to have been conducted by the United States Department of Health and Human Services ." The records show that Monsanto was able to prepare "a public relations assault" on the finding after they were alerted to the determination by Jess Rowland , the head of the EPA's cancer assessment review committee at that time, months in advance. Emails also showed that Rowland "had promised to beat back an effort by
1904-618: A significant hydrological and ecological connection to traditional navigable waters, interstate waters, and territorial seas. It is also referred to as the Waters of the United States (WOTUS) rule, which defines all bodies of water that fall under U.S. federal jurisdiction. The rule was published in response to concerns about lack of clarity over the act's scope from legislators at multiple levels, industry members, researchers and other science professionals, activists, and citizens. The rule
2016-580: A total of fourteen states had joined the suit—the U.S. Court of Appeals for the District of Columbia ruled that the EPA regulations violated the Clean Air Act. In response, EPA announced plans to propose such standards to replace the vacated Clean Air Mercury Rule, and did so on March 16, 2011. In July 2005 there was a delay in the issuance of an EPA report showing that auto companies were using loopholes to produce less fuel-efficient cars. The report
2128-528: Is frequently perceived on the political right as a burden on economic growth and an infringement of landowner rights. The Clean Water Rule was part of a larger mobilization by the Obama administration to ingrain the presidency with an environmental legacy, which Republicans have viewed as an “over-reach” of executive power. The pushback against the Clean Water Rule also include some Democrats from "farm and energy states". Some state and local governments also consider
2240-487: Is referred to as " watershed management ". In Brazil , the National Policy of Water Resources, regulated by Act n° 9.433 of 1997, establishes the drainage basin as the territorial division of Brazilian water management. When a river basin crosses at least one political border, either a border within a nation or an international boundary, it is identified as a transboundary river . Management of such basins becomes

#17327795641432464-705: Is the primary federal law regulating water pollution in the United States. The language of the Clean Water Act describes itself as pertaining to "Waters of the United States". The act defines these waters as "navigable waterways", which connects the act to constitutional authority to regulate interstate commerce. Two U.S. Supreme Court decisions, in 2001 and 2006, interpreted the law to include waters not presently navigable that were formerly navigable that might be readily dredged to be restored to navigation or be made available for navigation. The scope of these decisions cast into doubt lower court decisions interpreting
2576-404: Is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation , a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin , rather than flowing to the ocean, water converges toward the interior of the basin, known as a sink , which may be a permanent lake, a dry lake , or
2688-713: The African Great Lakes , the interiors of Australia and the Arabian Peninsula , and parts in Mexico and the Andes . Some of these, such as the Great Basin, are not single drainage basins but collections of separate, adjacent closed basins. In endorheic bodies of water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this

Congress also enacted the Resource Conservation and Recovery Act (RCRA) in 1976, significantly amending the Solid Waste Disposal Act of 1965 . It tasked the EPA with setting national goals for waste disposal, conserving energy and natural resources, reducing waste, and ensuring environmentally sound management of waste. Accordingly,
5600-461: The act's authority to extend regulatory authority to streams, wetlands, and small bodies of water not navigable in the sense of the interstate commerce clause. These decisions highlighted a need for the EPA and USACE to more precisely define and justify an implicit regulatory authority over tributaries flowing into the navigable waterways for which a clear statutory authority is provided. The Solid Waste Agency of Northern Cook County (SWANCC), Illinois,

EPA staff recall that in the early days there was "an enormous sense of purpose and excitement" and the expectation that "there was this agency which was going to do something about a problem that clearly was on the minds of a lot of people in this country," leading to tens of thousands of resumes from those eager to participate in
6160-638: The agency's Scientific Integrity Official, Francesca Grifo , from testifying at a House committee hearing. EPA offered to send a different representative in place of Grifo and accused the committee of "dictating to the agency who they believe was qualified to speak." The hearing was to discuss the importance of allowing federal scientists and other employees to speak freely when and to whom they want to about their research without having to worry about any political consequences. In September 2019 air pollution standards in California were once again under attack, as

#17327795641436944-430: The discharge of water from a basin may be made by a stream gauge located at the basin's outlet. Depending on the conditions of the drainage basin, as rainfall occurs some of it seeps directly into the ground. This water will either remain underground, slowly making its way downhill and eventually reaching the basin, or it will permeate deeper into the soil and consolidate into groundwater aquifers. As water flows through
7056-498: The discovery of many abandoned or mismanaged hazardous waste sites such as Love Canal , Congress passed the Comprehensive Environmental Response, Compensation, and Liability Act , nicknamed "Superfund." The new law authorized EPA to cast a wider net for parties responsible for sites contaminated by previous hazardous waste disposal and established a funding mechanism for assessment and cleanup. In
7168-441: The drainage area is dependent on the soil type. Certain soil types such as sandy soils are very free-draining, and rainfall on sandy soil is likely to be absorbed by the ground. However, soils containing clay can be almost impermeable and therefore rainfall on clay soils will run off and contribute to flood volumes. After prolonged rainfall even free-draining soils can become saturated , meaning that any further rainfall will reach
7280-697: The drainage basin to the mouth, and may accumulate there, disturbing the natural mineral balance. This can cause eutrophication where plant growth is accelerated by the additional material. Because drainage basins are coherent entities in a hydrological sense, it has become common to manage water resources on the basis of individual basins. In the U.S. state of Minnesota , governmental entities that perform this function are called " watershed districts ". In New Zealand, they are called catchment boards. Comparable community groups based in Ontario, Canada, are called conservation authorities . In North America, this function

On July 9, 1970, Nixon proposed an executive reorganization that consolidated many environmental responsibilities of the federal government under one agency, a new Environmental Protection Agency. This proposal included merging pollution control programs from a number of departments, such as
7616-463: The final rule. Implementation of the rule will discern any implications for environmental justice communities, though it is clear that "meaningful involvement from minority, low-income, and indigenous populations, as well as other stakeholders, has been a cornerstone of development of the final rule." Specific details that have been clarified by the rule are outlined below. A tributary, or upstream water, must show physical features of flowing water –
7728-475: The first time. Waters used in normal agricultural, ranching, or silvicultural activities, as well as certain defined ditches, prior converted cropland, and waste treatment systems continue to be excluded. Before the rule, almost any water could be put through an analysis that remained case-specific, even if it would not be covered under CWA. The rule limits use of case-specific analysis by providing certainty and clarity of protected vs non-protected water. Ultimately
7840-548: The fossil fuel industry. In 2017, the Presidency of Donald Trump proposed a 31% cut to the EPA's budget to $ 5.7 billion from $ 8.1 billion and to eliminate a quarter of the agency jobs.

The resulting ambiguity became a part of the stated rationale for EPA rulemaking activity that resulted in the 2015 Waters of the United States rule. Following the SWANCC ruling, the EPA (then under the George W. Bush administration ) issued guidelines in 2003 restricting regulatory review of some 20 million acres of isolated wetlands and gave advance notice of proposed rulemaking which would substantially narrow
8624-511: The mighty effort to clean up America's environment. When EPA first began operation, members of the private sector felt strongly that the environmental protection movement was a passing fad. Ruckelshaus stated that he felt pressure to show a public which was deeply skeptical about government's effectiveness, that EPA could respond effectively to widespread concerns about pollution. The burning Cuyahoga River in Cleveland, Ohio, in 1969 led to
8736-514: The most water, from most to least, are the Amazon, Ganges , and Congo rivers. Endorheic basin are inland basins that do not drain to an ocean. Endorheic basins cover around 18% of the Earth's land. Some endorheic basins drain to an Endorheic lake or Inland sea . Many of these lakes are ephemeral or vary dramatically in size depending on climate and inflow. If water evaporates or infiltrates into
8848-629: The nation's streams and rivers do not meet standards and most pollution issues come from nonpoint sources , such as agricultural runoff . Many people, 117 million according to EPA, rely on drinking water, in addition to many others who subside on fishing, from sources protected under the implementation of the rule. Low-income communities and communities of color are more often at risk of being affected by pollution. It has also been evidenced that, "states conduct fewer regulatory enforcement actions in counties with higher levels of poverty." The Environmental Justice Coalition for Water expressed, in its comment on
8960-478: The nearest navigable waters that his environmental consultant had classified as wetlands without a permit from the Michigan Department of Environmental Quality. Rapanos v. United States resulted in a 2006 Supreme Court decision with five justices concurring to vacate rulings against the defendants, but issuing three distinctly differing opinions leaving uncertain which of the described tests defined
9072-504: The nearly 1,600 EPA staff scientists who responded online to a detailed questionnaire reported they had experienced incidents of political interference in their work. The survey included chemists, toxicologists, engineers, geologists and experts in other fields of science. About 40% of the scientists reported that the interference had been more prevalent in the last five years than in previous years. President Barack Obama appointed Lisa P. Jackson as EPA administrator in 2009. In 2010 it
9184-846: The number of waste sites that are remediated in a given year. (In 2021 Congress reauthorized an excise tax on chemical manufacturers. ) Major legislative updates during the Clinton Administration were the Food Quality Protection Act and the 1996 amendments to the Safe Drinking Water Act. President George W. Bush appointed Christine Todd Whitman as EPA administrator in 2001. Whitman was succeeded by Mike Leavitt in 2003 and Stephen L. Johnson in 2005. In March 2005 nine states (California, New York, New Jersey, New Hampshire, Massachusetts, Maine, Connecticut, New Mexico and Vermont) sued
9296-610: The oath of office on December 4, 1970. EPA's primary predecessor was the former Environmental Health Divisions of the U.S. Public Health Service (PHS), and its creation caused one of a series of reorganizations of PHS that occurred during 1966–1973. From PHS, EPA absorbed the entire National Air Pollution Control Administration, as well as the Environmental Control Administration's Bureau of Solid Waste Management, Bureau of Water Hygiene, and part of its Bureau of Radiological Health. It also absorbed
9408-567: The passage of the Superfund law in 1980, an excise tax had been levied on the chemical and petroleum industries, to support the cleanup trust fund. Congressional authorization of the tax was due to expire in 1995. Although Browner and the Clinton Administration supported continuation of the tax, Congress declined to reauthorize it. Subsequently, the Superfund program was supported only by annual appropriations, greatly reducing
9520-417: The preparation of an annual environmental report. The conservation movement was weak at the time and the bill did not pass Congress. The 1962 publication of Silent Spring , a best-selling book by Rachel Carson , alerted the public about the detrimental effects on animals and humans of the indiscriminate use of pesticide chemicals. In the years following, Congress discussed possible solutions. In 1968,
9632-419: The presiding judge in a litigation brought about by people who claim to have developed glyphosate-related non-Hodgkin's lymphoma opened Monsanto emails and other documents related to the case, including email exchanges between the company and federal regulators. According to The New York Times , the "records suggested that Monsanto had ghostwritten research that was later attributed to academics and indicated that
9744-442: The proposed federal standards. It was reported that Johnson ignored his own staff in making this decision. In 2007 it was reported that EPA research was suppressed by career managers. Supervisors at EPA's National Center for Environmental Assessment required several paragraphs to be deleted from a peer-reviewed journal article about EPA's integrated risk information system , which led two co-authors to have their names removed from
9856-419: The public welfare—a decision that would trigger the first national mandatory global-warming regulations. Associate Deputy Administrator Jason Burnett e-mailed the draft to the White House. White House aides—who had long resisted mandatory regulations as a way to address climate change—knew the gist of what Johnson's finding would be, Burnett said. They also knew that once they opened the attachment, it would become
9968-414: The publication, and the corresponding author, Ching-Hung Hsu, to leave EPA "because of the draconian restrictions placed on publishing". The 2007 report stated that EPA subjected employees who author scientific papers to prior restraint , even if those papers are written on personal time. In December 2007 EPA administrator Johnson approved a draft of a document that declared that climate change imperiled
10080-418: The rainfall on the area of land included in its polygon. These polygons are made by drawing lines between gauges, then making perpendicular bisectors of those lines form the polygons. The isohyetal method involves contours of equal precipitation are drawn over the gauges on a map. Calculating the area between these curves and adding up the volume of water is time-consuming. Isochrone maps can be used to show
10192-631: The responsibility of the countries sharing it. Nile Basin Initiative , OMVS for Senegal River , Mekong River Commission are a few examples of arrangements involving management of shared river basins. Management of shared drainage basins is also seen as a way to build lasting peaceful relationships among countries. The catchment is the most significant factor determining the amount or likelihood of flooding . Catchment factors are: topography , shape, size, soil type, and land use (paved or roofed areas). Catchment topography and shape determine
10304-461: The river rather than being absorbed by the ground. If the surface is impermeable the precipitation will create surface run-off which will lead to higher risk of flooding; if the ground is permeable, the precipitation will infiltrate the soil. Land use can contribute to the volume of water reaching the river, in a similar way to clay soils. For example, rainfall on roofs, pavements , and roads will be collected by rivers with almost no absorption into
10416-500: The rule saves time and avoids further evaluation and the need to take the case to court. Specific watersheds have been shown to impact downstream water health. The rule protects Texas coastal prairie wetlands, coastal depressions called Carolina Bays and the related seasonal Delmarva bays, western vernal pools in California , pocosins , and other prairie potholes , when impacting downstream waterways. The Clean Water Act
10528-399: The rule until February 6, 2020. The Trump administration formally repealed the WOTUS rule on September 12, 2019 and published a replacement rule on April 21, 2020. On August 30, 2021, the United States District Court for the District of Arizona threw out the 2020 replacement rule. USACE and EPA published a revised definition of WOTUS on January 18, 2023, restoring the pre-2015 regulations on
10640-416: The rule was a "massive power grab" by the government on farmers, home owners, and land commissioners, stalling economic growth. On February 28, 2017 Trump signed an executive order directing EPA to review the Clean Water Rule for conflicts with his economic growth agenda. On March 6, 2017 the Trump administration announced its intent to review and rescind or revise the rule. The Trump administration's choice for
10752-418: The rule, the need to "strengthen the categorical protections" to wetlands, to minimize flooding and support pollution remediation. While there are no direct implications for indigenous peoples , tribal communities were consulted during the process of finalizing the Clean Water Rule. A separate, revised interpretive rule to the Clean Water Act, section 518, determined tribal lands should be treated as states and
10864-424: The scope of WOTUS and weaken CWA protections. After strong opposition from Congress the planned legislation was abandoned, to the relief of environmental advocates and disappointment of land development groups who sought a reduction in federal wetlands protection. The lack of a majority opinion in the 2006 Rapanos case prompted a second set of EPA guidelines directing the agency to determine wetlands protection on
10976-663: The scope of federal jurisdiction over waterways, effective March 20, 2023. On May 25, 2023, the United States Supreme Court ruled in the case Sackett v. Environmental Protection Agency that only wetlands and permanent bodies of water with a "continuous surface connection" to "traditional interstate navigable waters" are covered by the Clean Water Act, narrowing the application of the Clean Water Rule. The 2015 rule ensures that Clean Water Act (CWA) programs are more precisely defined and intends to save time and avoid costs and confusion in future implementation of
11088-418: The speed with which the runoff reaches a river. A long thin catchment will take longer to drain than a circular catchment. Size will help determine the amount of water reaching the river, as the larger the catchment the greater the potential for flooding. It is also determined on the basis of length and width of the drainage basin. Soil type will help determine how much water reaches the river. The runoff from
11200-415: The time taken for rain to reach the river, while catchment size, soil type, and development determine the amount of water to reach the river. Generally, topography plays a big part in how fast runoff will reach a river. Rain that falls in steep mountainous areas will reach the primary river in the drainage basin faster than flat or lightly sloping areas (e.g., > 1% gradient). Shape will contribute to
11312-477: The time taken for runoff water within a drainage basin to reach a lake, reservoir or outlet, assuming constant and uniform effective rainfall. Drainage basins are the principal hydrologic unit considered in fluvial geomorphology . A drainage basin is the source for water and sediment that moves from higher elevation through the river system to lower elevations as they reshape the channel forms. Drainage basins are important in ecology . As water flows over
11424-729: The world's land drains to the Atlantic Ocean . In North America , surface water drains to the Atlantic via the Saint Lawrence River and Great Lakes basins, the Eastern Seaboard of the United States, the Canadian Maritimes , and most of Newfoundland and Labrador . Nearly all of South America east of the Andes also drains to the Atlantic, as does most of Western and Central Europe and
11536-619: Was based on ideas that had been discussed in the 1959 and subsequent hearings. The Richard Nixon administration made the environment a policy priority in 1969-1971 and created two new agencies, the Council on Environmental Quality (CEQ) and EPA. Nixon signed NEPA into law on January 1, 1970. The law established the CEQ in the Executive Office of the President. NEPA required that a detailed statement of environmental impacts be prepared for all major federal actions significantly affecting
11648-479: Was contested in litigation. In 2017 the Trump administration announced its intent to review and rescind or revise the rule. A Supreme Court ruling on January 22, 2018 returned the rule's nationwide authority after the rule was decided to be illegal by a lower court. It gave back jurisdiction previously complicated by decisions from the circuit courts of appeals. Two weeks later, the Trump administration formally suspended
11760-414: Was denied federal permits to develop an old gravel mine site into a landfill because migratory bird ponds had developed in abandoned excavation trenches on the property. The Supreme Court ruled in 2001 that the authority granted by CWA did not extend to abandoned gravel pits with seasonal ponds. In 1989, land developer John Rapanos filled twenty-two acres (nine hectares) on his property some 10-20 miles from
11872-500: Was illegal, and additionally charged that the EPA's system of cap-and-trade to lower average mercury levels would allow power plants to forego reducing mercury emissions, which they objected would lead to dangerous local hotspots of mercury contamination even if average levels declined. Several states also began to enact their own mercury emission regulations. Illinois's proposed rule would have reduced mercury emissions from power plants by an average of 90% by 2009. In 2008—by which point
11984-794: Was made effective in May 2016. This amendment is important for giving people living on reservations access to EPA regulation and federal grants; tribes no longer need to "demonstrate inherent authority to regulate" their waters. The regulation at the state level is determined by the strength of federal coverage and some stakeholders consider the rule to be overreach by the government. There is concern from private landowners, including small business owners and farmers, that this "rule will lead to radical environmental groups suing homeowners and small businesses," and, ultimately, "increased regulatory costs, less economic development, fewer jobs." Government regulation and protection of fresh water supplies and watershed health
12096-461: Was no change to the exemptions for activities necessary to forestry, ranching, or farming. The rule provided clearer protection of many waters of the U.S. that, if polluted, could have detrimental effects on drinking water, habitats, and flood-prone areas. One U.S. water news organization stressed that, while the rule was an update to the CWA, there is still a need for more regulation since more than half of
12208-540: Was reflected in the 1990 amendments to the Clean Air Act and in new approaches by the agency, such as a greater emphasis on watershed -based approaches in Clean Water Act programs. In 1992 EPA and the Department of Energy launched the Energy Star program, a voluntary program that fosters energy efficiency. Carol Browner was appointed EPA administrator by President Bill Clinton and served from 1993 to 2001. Major projects during Browner's term included: Since
12320-442: Was reported that a $ 3 million mapping study on sea level rise was suppressed by EPA management during both the Bush and Obama administrations, and managers changed a key interagency report to reflect the removal of the maps. Between 2011 and 2012, some EPA employees reported difficulty in conducting and reporting the results of studies on hydraulic fracturing due to industry and governmental pressure, and were concerned about
12432-536: Was supposed to be released the day before a controversial energy bill was passed and would have provided backup for those opposed to it, but the EPA delayed its release at the last minute. EPA initiated its voluntary WaterSense program in 2006 to encourage water efficiency through the use of a special label on consumer products. In 2007 the state of California sued the EPA for its refusal to allow California and 16 other states to raise fuel economy standards for new cars. EPA Administrator Stephen Johnson claimed that
12544-544: Was vocal about environmental issues. Following his election victory, he appointed William K. Reilly , an environmentalist, as EPA Administrator in 1989. Under Reilly's leadership, the EPA implemented voluntary programs and initiated the development of a "cluster rule" for multimedia regulation of the pulp and paper industry. At the time, there was increasing awareness that some environmental issues were regional or localized in nature, and were more appropriately addressed with sub-national approaches and solutions. This understanding
