<br /> <br />. <br /> <br />36. July. August, and September mean flows will be reduced <br /> <br />64 percent. 77 percent, and 49 percent, respectively, in this segment, <br />and in July the minimtnn flow will be lowered by about one-half. Of <br />even more consequence during these same months is the fact that the <br />flow will be reduced to an unvaryingly low level. August flows will <br />be 16 second~feetl with few exceptions September flaws will be only 1 <br />second-foot greater. The increased frequency and the extended period <br />of extremely low flows are expeoted to resul t in muoh shallower water <br />depth, considerably diminished water surfaoe. and lowered production <br />of food. These faotors will reduce the quality of this section of the <br />Rio Grande as a trout fishery and will adversely affect fall-spawning <br />brown trout. <br />Alamosa to Conejos River <br />37. The damaging aspects as described above will also occur <br /> <br />below Alamosa for a few miles until return flows from seepage, drains, <br /> <br />and tributaries enter the river and eliminate these adverse conditions. <br /> <br />Summer flows will average somewhat less than those without the projeot <br />but minimum flows will be enough higher to more than offset the over- <br />all reduction of average summer flow. Winter flows will be reduced <br />but not enough to affect the fishery resource. Below the Conejos <br />confluence effects of the project will be masked by flow contributions <br />from the Conejos and Red Rivers. <br />Reservoir characteristics <br /> <br />38. The reservoir will have a surface area of 1.380 acres and <br /> <br />13 miles of shoreline at average annual minimum pool. Annual water <br /> <br />level IT uctuations will be great, averaging about 90 feet with a <br /> <br />'; <br /> <br />. <br /> <br />": <br /> <br />20 <br /> <br />1168 <br /> <br />
