this summary is from the nebraska game and parks commission project for the habitat restoration of nine mile creek by jeff blaser.
"Nebraka's surface water resources include over 280,000 acres of standingwater and more than 23,680 miles of flowing water, most of which flow through private lands. The state's flowing waters are divided into thirteen river basins. These river basins are comprised of approximately 2,130 rivers/streams/creeks. Flowing waters provide important and at times critical habitat for terrestrial and aquatic wildlife. All seven of Nebraska's endangered and threatened fish species are associated with flowing waters. Flowing waters also provide a wide range of outdoor recreational opprotunities (fishing, canoeing, sight seeing, etc.) for Nebraskans.
Nebraska Department of Environmental Quality (NDEQ) divides flowing waters into two classifications- Coldwater (Class A and Class B) and Warmwater (Class A and Class B).
Coldwater are waters which provide, a habitat capable of maintaining year-round populations of coldwater biota where temperatures exceed 25 degrees C (77 degrees F). Warmwater are waters where temperatures frequently exceed 25 degrees C.
Coldwater are waters which provide, a habitat capable of maintaining year-round populations of coldwater biota where temperatures exceed 25 degrees C (77 degrees F). Warmwater are waters where temperatures frequently exceed 25 degrees C.
Class A Coldwater are waters that provide a habitat which supports natural reproduction of a trout population. These waters are also cabable of maintaining year-round populations of a variety of other coldwater fish and associated vertebrate and invertebrate organisms and plants.
Class B Coldwater are waters which provide or could provide seasonal migration of trout, do not support natural reproduction of trout, or may be able to maintain trout year-round if peridically stocked. The NDEQ surface water quality standards identify only 41 CLASS A COLDWATER STREAMS (about 2% of total flowing waters) in the state consisting of 565 streams miles (2.4% of state's total stream miles). This indicates the importance of trying to protect and or enhance the state's Class A Coldwater streams."
