McConaughy Reservoir and the North Platte River drainage upstream to the Nebraska-Wyoming state line represent a major part of the coldwater habitat in Nebraska, 87%, according to the 1972 Nebraska Fish and Wildlife Plan (Figure 1). The plan also showed the upper North Platte River drainage contains 159 miles of coldwater stream habitat and 192 miles of mixed cold and warm water stream habitat, 29 percent of the total mileage in the state. Together, these 351 miles account for 80 percent of the coldwater stream acreage in Nebraska.
