<br />estimates of habitat areas were only rough approximations; estimates of riffle wetted perimeter are <br /> <br />better, but simulated wetted perimeters at discharges <134 cfs are suspect because of <br /> <br /> <br />extrapolation problems. The study would have benefitted if current site specific habitat suitability <br /> <br /> <br />curves had been developed. The greatest shortcoming, however, was that the study design should <br /> <br /> <br />have included seasonal flow and fish habitat use, not just base flows. <br /> <br /> <br />Finally, under the current flow regime (the past 20 years), the Colorado pikeminnow <br /> <br /> <br />population has done well in the White River. Unfortunately, it is unknown why it attracts so <br /> <br /> <br />many Colorado pikeminnow. Until additional information becomes available, we recommend <br /> <br />continuation of the current flow patterns to protect the Colorado pikeminnow in the White River. <br /> <br />IX <br />
