3077 . the five vinter months (November - March) the average minimum mean daily flovs of the Arkansas River near Pueblo for the period 1941 - 1970 ranged from 130 c.f.s. to 250 c.f.s. This could adversely affect the fishing in thc siK miles of Arkansas River immediately below the dam during winter months. According to the Bureau of Sport Fisheries and Wildlife under the present vinter water storage plan, when native waters are stored in Pueblo Reservoir, the reduction of the Arkansas River flows below Pueblo Dam viII displace about 25,000 ducks annually from the Arkansas River, belov Pueblo, to the panhandle of Texas and Oklahoma. It is the freezing of the river, associated with the reduced flovs, that viII actually cause the displacement. . 13. After impoundment, flora and fauna immediately surrounding the reservoir viII change from riparian to a lake/lakeshore type. Some aquatic plant and animal life will increase significantly. Riparian vegetation downstream from the dam will eventually increase adJecent to the river as a result of regulated stream- flov. Upstream from the reservoir, a salt cedar- cottonwood bosque growth is expected to become established. This would enhance habitat for mourning doves, scaled quail, cottontails, and songbirds, as veIl as provide much-needed food and cover for deer. Hanagement of this phreatophytic o:rovth vill be coordinated vith the Colorado Division of Game, Fish and Parks and the Bureau of Sport Fisheries and Wildlife. 14. Exclusion of uncontrolled grazing from the reservoir area, coupled with a resource management and environmental improve- ment plan, viII protect the open-space values anu promote a near "pre-cowboy economy grassland" vith native flovering plants. The control of grazing, and reneved plant vigor viII deter water and vindsheet erosion. Gully erosion viII be sub- stantially curtailed. With land management oriented toward stimulation of wildlife populations, the whitetail deer popula- tion should maintain itself and hopefully increase. Mule deer. which are not acclimated to people, will possiblY decrease in population. Large cottonwood trees viII be preserved above the high water- line at the upper vest end of the reservoir. Thcse trees, being adjacent to such a large body of vater, should be attractive to birdlife and useful as roosting sites for bald eagles, especially during the winter. 41 .
