29-604: The Boise River rises in three separate forks in the Sawtooth Range at elevations exceeding 10,000 feet (3,050 m), and is formed by the confluence of its North and Middle forks. The North Fork, 50 miles (80 km) long, rises in the Sawtooth Wilderness Area , along the Boise – Elmore county line, 60 miles (100 km) northeast of Boise. It flows generally southwest through the remote mountains in

58-410: A greater variety of fish. The most prevalent species on this section is mountain whitefish , as well as hatchery-reared rainbow trout , wild rainbow trout, and fingerling brown trout . Upstream from Lucky Peak and Arrowrock reservoirs, the river and its tributaries contain excellent populations of wild rainbow trout, mountain whitefish, and bull trout. This is especially true immediately downstream from

87-493: A variety of flies mimicking the abundant aquatic and terrestrial insects present in the watershed, as well as streamers. Elevation The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid , a mathematical model of the Earth 's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum ). The term elevation

116-552: Is a recreational and alternate transportation trail along the banks of the Boise River through Boise , Idaho , United States. The Boise Greenbelt is more of a greenway than a green belt since its character is linear. It extends more than 20 miles (32 km) beginning at Lucky Peak Dam in the east to a short distance beyond Eagle Road ( Idaho State Highway 55 ) in the west in Eagle, Idaho . Taking into account both sides of

145-565: Is developing a 3D Elevation Program (3DEP) to keep up with growing needs for high quality topographic data. 3DEP is a collection of enhanced elevation data in the form of high quality LiDAR data over the conterminous United States, Hawaii, and the U.S. territories. There are three bare earth DEM layers in 3DEP which are nationally seamless at the resolution of 1/3, 1, and 2 arcseconds.

174-490: Is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface. Elevation is not to be confused with the distance from the center of the Earth. Due to the equatorial bulge , the summits of Mount Everest and Chimborazo have, respectively,

203-467: Is on the north bank 1-mile (1.6 km) west of the central point one would see a DOT with the inscription NW 1.0. If one is on the south bank 5.3 miles (8.5 km) east of the central point, one would see the inscription SE 5.3. A stretch of greenbelt west of Glenwood Street in Garden City on the north side has been closed in varying degrees over the last three decades. The former Idaho state land

232-575: Is the century-old Boise River Diversion Dam for the concrete New York Canal, which terminates at Lake Lowell (a.k.a. Deer Flat Reservoir) southwest of Nampa in Canyon County . The next diversion is for the Ridenbaugh Canal (1878) at Eckert Diversion Dam, immediately above Barber Park, five miles (8 km) from downtown Boise. Wooded through the city, the river is lined by an extensive recreational greenbelt . It flows west across

261-639: The Boise National Forest . The Middle Fork, approximately 52 miles (84 km) in length, rises within 12 miles (19 km) of the North Fork in the southern Sawtooth Wilderness Area in northeastern Elmore County. It flows west-southwest near the town of Atlanta , joining the North Fork to form the Boise River, approximately 15 miles (24 km) southeast of Idaho City . The main stream flows southwest into Arrowrock Reservoir , joining

290-562: The Treasure Valley . The major projects' initial completion dates were: The Boise River was proposed for 50 years for a dam at Twin Springs, culminating in a 1966 Project Travois proposal, which would have used nuclear explosives to either create large amounts of rockfill aggregate for dam construction, or to induce a landslide that would have much the same effect. Project Travois was a component of Project Plowshare . The project

319-489: The 6-mile (10 km) trip. Water skiing is popular above the dam at the Lucky Peak Reservoir. On the lower (warmwater) course of the river, low summer flows and poorer water quality from agricultural runoff limit fishery production. This section of river supports a fair fishery for largemouth bass , smallmouth bass, and channel catfish . Upstream from Star , the river is a coldwater stream and supports

348-646: The Americana Boulevard bridge westward to the Main Street bridge. At the downstream side of the Main Street bridge the south bank trail resumes to approximately 1 ⁄ 4 -mile (400 m) east of the Western Idaho Fairgrounds at East 52nd Street. A brief detour via East 52nd Street, Alworth Street and Remington Street returns users to the south bank Greenbelt and continues westward approximately 1-mile (1.6 km) west of

377-636: The City of Boise as it worked to develop the Greenbelt, and in 1971 the first Greenbelt Ordinance was adopted which required a minimum setback of 70 feet (21 m) for all structures and parking areas. The City of Boise continued to slowly piece together a patchwork of land along the corridor using several methods of acquisition including purchase, exchange, leasing and receiving donations of property by individuals, civic groups and corporations. Approximately 1.5 miles (2.4 km) west of Veterans Memorial Parkway

406-664: The Glenwood Street Bridge. DOTS is an acronym for Distance & Orientation Trail System. Serving as mileposts, there are over 100 white dots 18 inches (45 cm) in diameter painted on the greenbelt. The purpose of the DOTS is to aid people in locating their position on the greenbelt relative to the downtown Boise central point. The central point, mile 0, is located near the intersection of 8th Street and River Street in downtown Boise. The DOTS are spaced at 1 ⁄ 10 -mile (160 m) increments. For example, if one

435-447: The Greenbelt. Segways are allowed on the Greenbelt in the City of Boise providing a special permit has been obtained. In 1962, the City of Boise hired a consultant, Atkinson & Associates, to create Boise's first comprehensive plan. The plan suggested the city should acquire land along the Boise River to create a continuous "green belt" of public lands stretching the entire length of the community. A local grassroots effort to clean up

464-494: The Parkcenter Boulevard area bicycling is prohibited on a section which is unpaved and follows the river bank for approximately 2 miles (3.2 km) from Barber Park to East River Run Drive. Bicyclists are routed on a circuitous route on residential neighborhood streets. A more significant gap in the south bank trail is at the west end of Ann Morrison Park where there is a 1 ⁄ 2 -mile (800 m) gap from

493-541: The Riverside Village residential development. The bicycle dismount zone continues approximately 1.5 miles (2.4 km) westward. As of April 2008 Garden City has made it a misdemeanor to ride a bicycle on the greenbelt through Riverside Village. However, there is a roughly parallel signed bicycle route which allows bicyclists to continue westward on residential streets to the City of Eagle greenbelt without having to ride on busy State Street (State Highway 44). In

522-772: The South Fork from the Anderson Ranch Dam . The 101-mile-long (163 km) South Fork rises in northern Camas County in the Smoky Mountains and Soldier Mountains of the Sawtooth National Forest north of Fairfield , 65 miles (105 km) east of Boise. It flows generally southwest, descending through a basalt canyon to fill the Anderson Ranch Reservoir , then turns northwest in central Elmore County. It joins

551-500: The early 19th century, named after Pacific Fur Company employee John Reed , who explored parts of the river throughout 1813 and 1814. The river is diverted to canals for irrigation on the plain west of what is now Boise. The dams that form the mountain reservoirs were constructed as part of the Bureau of Reclamation's "Boise Project" to provide agricultural irrigation, hydroelectricity , drinking water, and flood control to Boise and

580-582: The landscape at different scales. Tools inside the GIS allow for manipulation of data for spatial analysis or cartography. A topographical map is the main type of map used to depict elevation, often through contour lines . In a Geographic Information System (GIS), digital elevation models (DEM) are commonly used to represent the surface (topography) of a place, through a raster (grid) dataset of elevations. Digital terrain models are another way to represent terrain in GIS. USGS (United States Geologic Survey)

609-621: The largest elevation and the largest geocentric distance. In aviation, the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is not to be confused with terms such as the altitude or height. GIS or geographic information system is a computer system that allows for visualizing, manipulating, capturing, and storage of data with associated attributes. GIS offers better understanding of patterns and relationships of

638-414: The main stream as the southern arm of Arrowrock Reservoir, 20 miles (32 km) east of Boise. Downstream from its confluence with the South Fork, the river flows generally west, adds the major tributary of Mores Creek along Highway 21 , and passes through Lucky Peak Dam to emerge from the foothills southeast of Boise. It passes over several irrigation diversion dams above the city, the first and largest

667-472: The north bank trail ends. However, two pedestrian bridges carry traffic to the south bank trail via an area known as Plantation Island. The north bank trail resumes at the Glenwood Street bridge approximately 1-mile (1.6 km) west of the first Plantation Island pedestrian bridge. Also on the north bank, approximately 1/4 mile west of Glenwood Bridge the greenbelt becomes a bicycle dismount zone at

696-412: The outflow of Anderson Ranch reservoir, where the South Fork takes on the characteristics of a classic "tailwater" for over 5 miles (8 km) from the put-in below the dam to Cow Creek Bridge. The Boise River is also popular for fishing , mostly for rainbow trout and, in the winter, steelhead . Spin-fishermen use roostertail spinners and bait such as worms and Powerbait, while fly fishermen use

725-553: The river and other parallel trails and spurs, the total Greenbelt trail system measures more than 30 miles (48 km). The Greenbelt connects Boise's riverside parks and connects Boise with neighboring municipalities. The majority of the Greenbelt is paved with asphalt or concrete on both sides of the river. However some sections are unpaved and bicycles may be prohibited on some unpaved sections. Where this occurs, bicycles have alternate routes on residential streets or dedicated bike paths. Motorized vehicles are prohibited on all parts of

754-456: The waterway and create public access to the river corridor began to take hold. This vision caught on, and by 1967 three small parcels of land were donated to the city to launch the "green belt." In 1968, with public interest and support growing, the first Greenbelt Plan and Guidelines were adopted by the Board of Parks Commissioners. A Greenbelt and Pathways Committee was appointed in 1969 to guide

783-655: The western end of the Snake River Plain in the Treasure Valley and becomes a braided stream with a wide floodplain as it crosses northern Canyon County to the Snake River . At an approximate elevation of 2,100 feet (640 m), it enters the Snake River, the Idaho- Oregon border, west of Parma and three miles (5 km) south of Nyssa , Oregon . The river was called "Reed's River" in

812-402: Was abandoned in 1968 after concerns were raised about radiological contamination, and the seismic safety of downstream dams. The river is a popular destination for floating, specifically on the Boise greenbelt . Tubers and floaters launch at Barber Park and land at Ann Morrison Park, between major irrigation diversion dams. Several minor diversion weirs are passed as well as several bridges on

841-483: Was offered on condition that "...they shall construct certain improvements on the State land consisting of a bike path, lakes, pedestrian bridges (where the latter are required to assure a continuous linkage of greenbelt next to the Boise River for the length of the Riverside Village project)...", but these terms have never been met. At one point a stretch even had a sign posted stating "Private Property. No Trespassing. This
