CHAPTER 3 <br />AFFECTED ENVIRONMENT AND ENVIRONMENTAL CONSEQUENCES <br />Table 3.6-1. Winter flows would not be altered. This gain is accomplished by transferring the depletion <br />associated with 10,000 acres of irrigated land to M&I use. <br />The increased flows are less than 10 percent of the average baseline flow conditions. This would result <br />in an immeasurable to slight benefit to the Pine River fishery. <br />Table 3.6-1 <br />Approximate Average Monthly Increases in the Pine River <br />Under Refined Alternative 6 <br />Month Flow (cfs) <br />April 7 <br />May 32 <br />June 55 <br />July 54 <br />August 47 <br />September 28 <br />October 9 <br />Mitigation for Refined Alternative 6 Aquatic Resource Impact 3: No mitigation is proposed. <br />3.6.4.3 No Action Alternative <br />The follow impacts of the No Action Alternative were taken from the 1996 FSFES. <br />Trout Fishery <br />Animas River - Under this alternative, the CDOW is expected to continue to manage the Animas River <br />trout fishery in a manner similar to that of the last several years. Wild trout strains for stocking may <br />become more difficult to obtain in future years. Barring changes in the relative success of natural <br />reproduction by trout in the Animas River, reduced stocking concentrations of wild trout could <br />eventually lead to a reduction in the numbers and overall biomass of trout. The Animas River within the <br />confines of the Southern Ute Indian Tribe Reservation would maintain the potential for a better trout <br />fishery throughout much of its length, if it were provided more and better strains of wild trout.' At <br />present, these fish are not available; therefore, in the foreseeable future, it is anticipated that the river's <br />trout population within the Southern Ute Indian Tribe Reservation would remain low. The trout fishery <br />downstream from the Colorado-New Mexico State line would remain low quality. This is because of an <br />increase in seasonal water temperatures, other deteriorating water quality conditions and reduced <br />physical habitat because of man-induced instream alterations and flow reductions related to municipal, <br />industrial, and irrigation uses. (Page III-34) <br />Wild trout are species that have not been subjected to severe inbreeding due to artificial propagation. Therefore, <br />"wild trout" exhibit wider genotypic and phenotypic characteristics that overall allow for greater survival in natural <br />f environments, when stocked. &3#MAS 4LA-CIEZ GZAV6L,. aeeminuche Construction ALlt.'_'a^riqu <br />G1W iP?CC IA - PA6G It •8t , <br />3.6 AQUATIC RESOURCES 3-108 .O Box AA - TQJwaoc, C0 `'`
