Comment: <br /> <br />Response: <br /> <br />45. Comment: <br /> <br />Response: <br /> <br />standpoint, large losses of trout would likely result in reduced numbers of <br />fish caught, Reclamation has committed to collecting numerous large <br />trout from this portion of the river prior to the test and to retumfish <br />immediately after the test is finalized, This effort would be coordinated <br />with the New Mexico Department of Game and Fish. Also, Reclamation <br />would contribute monies not to exceed $25,000 for the acquisition of <br />fingerling trout (2-4 inches) to stock downstream of Citizen 's Ditch. Also, <br />Reclamation will work with water diversion companies to encourage them <br />to minimize flow depletions to the San Juan River without jeopardizing <br />their legal water rights, Last, several water quality parameters would be <br />monitored during the test to anticipate and avoid (stopping the test) <br />significant losses to the existing trout fishery, <br /> <br />Reclamation needs to consider mitigation for all fish losses below Navajo <br />Dam to restore the trout population as soon as possible to minimize <br />recteational and economic impacts, <br />See response to Comment No, 4/ describing Reclamation's proposed <br />fishery plan. <br /> <br />It is unclear if this test is also to evaluate the potential impact to the blue <br />ribbon trout fishery below Navajo Dam and irrigation users, <br />The test would indeed include monitoring the trout fishery downstream <br />from Navajo Dam although there currently exists a lot of information <br />pertaining to the Quality Waters section (identified by the New Mexico <br />Game and Fish Department as the first 4 miles of the fishery downstream <br />from the dam) collected in /996-97 and through the winter of 2000-200/, <br />Also, a trout health assessment will be conducted later this summer <br />(August) to collect information pertaining to the relative health of the <br />trout fishery during summer conditions, This assessment will be <br />compared to similar assessments done at other times of the year, <br /> <br />Where are the six locations for temperature modeling and are they habitat <br />or spatially specific? <br />The six temperature recorders are located at the dam and atfive other <br />locations downstream to the Hammond Diversion, a river distance of <br />about /5 miles, At this time, Reclamation will utilize the temperature data <br />for impact assessment but will not develop a temperature model, <br /> <br />Minimum flows in the ttout section should be 500 cfs and we would prefer <br />an average of 600-900 cfs, <br />It is recognized that a 500 cfs "minimum release" would provide better <br />conditions for the trout fishery than 250 cfs, However, there is no <br />established minimum set for the river and New Mexico does not have an <br /> <br />23 <br />
