A lacustuary is a freshwater body of water where river and lake waters mix. Lacustuaries are nonmoving or "slack" water, although water in them can ebb and flow due to lake waves moving in and out, and the rising and falling of lake water levels.
5-525: The Mink River is a 1.4-mile-long (2.3 km) lacustuary , or freshwater estuary, near the northern tip of the Door Peninsula of Wisconsin , in the United States . It is noted for its excellent bass fishing , and the area boasts more than 200 species of birds. The river flows in a southeasterly direction into the estuary on Rowleys Bay , Lake Michigan , 4 miles (6 km) southeast of
10-808: A lacustuary is dominated by plant and animal species adapted to lucustrine conditions. Common plants species observed in Ohio (Thoma: personal observation) were Pondweeds (Potamogeton sp.) and Eelgrass (Vallisneria) in clean, clear waters. Eurasian Watermilfoil (Myriophyllum spicatum) and Elodea sp. dominate in polluted, turbid waters. In clean waters fish communities are dominated by native Sunfish (Lepomis sp.), Minnows of several genera, and other phytophilic species such as Yellow Perch (Perch flavescens). In polluted, turbid, and organic enriched waters non-native fish species such as Common Carp (Cyprinus carpio) can dominate in both numbers and biomass. Specifically, in Lake Erie
15-404: The free-flowing water further upstream, and they play important roles in the ecology of both lake and river ecosystems . Lacustuary vegetation is also markedly different from shoreline and upland habitats. Not all streams which enter a lake have a lacustuary. Man-made ship channels may also be lacustuaries, depending on their slack water status. Biological characteristics' The biota of
20-540: The lacustuary is that portion of the river directly affected by rising and falling water levels in the lake. Lacustuaries are generally nonmoving or "slack" water. Lacustuaries are not estuaries . They are far less saline , as lacustuaries are freshwater bodies. Additionally lacustuaries tend to be less saline the closer to the lake, where as estuaries are more saline the closer to the ocean. Lacustuaries also have different functions than estuaries. Their physical and biological characteristics are also much different from
