pikeminnow has been eliminated by the mainchannel barrier, Taylor Draw Dam. Colorado

pikeminnow use a variety of habitats throughout the year, including runs and pools for resting

during the day and riffles for foraging at night.

The recovery program goal is to recovery endangered fishes while allowing existing and

new water development to proceed in the upper basin. The Recovery Implementa.tion Program's

Recovery Action Plan has as one of its recovery elements to identify and protect instream flows.

The purpose of this report is to develop year-round flow recommendations that maintain channel

integrity, promote habitat diversity and complexity, and protect Colorado pikeminnow habitat

under low flow conditions in the White River. The overall project goals were to:

1. Determine the relationship of river peak discharge to channel morphology in the

White River, ,

2. Determine habitat available to adult Colorado pikeminnow in the White River at

alternative low flow scenarios, and

3. Incorporate data from the above objectives to develop year-round flow

recommendations for the White River that identify channel maintenance

requirements, minimum low-flows for Colorado pikeminnow, and guidelines for

releases at Taylor Draw Dam.

This task was approached through two independent studies, one to evaluate the peak

flows needed to maintain channel stability and diversity, and the second to identify habitat

available to Colorado pikeminnow during the base-flow period. The first study addressed

Objective 1 and was conducted by Dr. John Schmidt and K. Lynn Orchard, Utah State

University. The second study addressed Objective 2 and was conducted by Dave Irving, Bruce
