<br />003349 <br /> <br />Benchmark 11 -' Maximum Water Yield Level <br /> <br />Arapaho/Roosevelt FEIS <br /> <br />The maximum potential for water yield for the Forest within water <br />quality standards is 2.21 million acre-feet per year. compared to the <br />current level of 1. 97 million acre-feet. The maximum potential was <br />estimated from the maximum allowable yield calculations for each <br />watershed in the Forest. Activities needed to achieve this maximum <br />potential include clearcuts on deep soil land types at optimum elevations <br />and aspects, the creation of optimally located and sized openin~s in <br />forested areas. and the installation of snow fences in suitable <br />high-elevation locations. <br /> <br />This benchmark was based on the followin!\,: <br /> <br />o Wilderness limits the acreage that is available for vegetation <br />treatment; <br /> <br />o One out of every two forested acres would be maintained in a <br />clcarcut condition; <br /> <br />o Many conflicts with other resources. such as wildlife. recreation <br />downhill skiing opportunities. and aesthetics would exist; <br /> <br />o Loggin!\, on steep or unstable (high cost) forested slopes would be <br /> <br />necessary; <br /> <br />o Access would be developed into previously unroaded watersheds; <br />and <br /> <br />o Budget constraints do not limit snow fence construction. <br /> <br />~ ,') \ <br /> <br />!l. ,~ <br />
