<br />001588 <br /> <br />2. Design the reservoir so it can be completely drained and drain it on a regular basis. If a <br />conservation pool or dead storage pool is maintained, it greatly increases the risk of <br />establishing permanent populations of non-native fishes in the reservoir. <br />3. Close the reservoir to public access and do not allow fishing. <br />4. Do not stock non-native fish in Long Hollow Reservoir. <br /> <br />Measures should be taken to provide adequate flows to maintain native fishes in the La Plata <br />River from Cherry Creek to the state line. It is recommended that a year-round minimum base <br />flow of 4 cfs be maintained in the La Plata River from Long Hollow confluence to the state line. <br />This may necessitate occasional releases from Long Hollow Reservoir. Flows in the La Plata <br />River from Cherry Creek to Long Hollow Creek should not be depleted below historic, pre- <br />project levels. We firmly believe these flows should be protected from diversion in Colorado <br />using the tools available under Colorado water law (an instream flow water right or acquisition <br />agreement with the Colorado Water Conservation Board). <br /> <br />Additional fish habitat improvement, channel restoration, and riparian protection are <br />recommended for the La Plata River between the state line and Cherry Creek to replace native <br />fish habitat lost by construction of Long Hollow Reservoir. Pool habitat is presently scarce in the <br />reach between Long Hollow Creek and Cherry Creek. Stream habitat improvement and riparian <br />protection could help native fish survive during periods oflow flow. Conservation easements or <br />some other form of permanent protection is needed for the stream channel and riparian corridor <br />within the habitat replacement area. <br /> <br />5 <br />
