Sport hunting for other animals such as <br />racoons, coyotes and foxes will be decreased as the result of the res- <br />ervoir inundation of the lands. There will be minor impacts on big <br />game animals. <br /> <br />No adverse downstream water quality effects are anticipated. The <br />operation of the dam and reservoir will reduce the seasonal and cyclical <br />fluctuations in the water supply and permit better water quality to be <br />applied to irrigation lands. Construction of the Narrows Dam and Res- <br />ervoir and development of the Jackson Lake Reservoir will create a <br />quality water-oriented outdoor recreation and fish and wildlife resource <br />for public use. Historical or archaeological sites or resources have <br />been surveyed in accordance with the National Historic Preservation Act. <br />Protection and preservation of historic and cultural resources will be <br />in compliance with Executive Order 11593 and 36 CFR 800. <br /> <br />Current Status <br /> <br />Advance planning on the project was essentially completed in 195i. Ie <br />After the project's re-authorization in 1970, advance planning began dr~ <br />anew and is now virtually completed. It is expected that repayment <br />contracts for the project will be executed by the Lower South Platte <br />Water Conservancy District, the Central Colorado Water Conservancy Dis~ <br />trict, and the state of Colorado in a few months. The available project <br />water has been oversubscribed in the Lower South Platte District and <br />the conservancy board will have to make a decision concerning water <br />allocation. <br /> <br />Current flood data necessitated a restudy of the Narrows Dam dr-- <br />design which increased the project cost and delayed filing of the envi- vf~ <br />rbnmenta1 statement. The Bureau of Reclamation filed a draft environ- <br />mental statement on December 8, 1975.

It is a major livestock feeding <br />and processing center. Chronic shortages of available water supplies <br />1eaa to constant litigation and decreased crop yield. The only <br />remaining flows available in the South Platte River for use in Colorado <br />are those which escape at the state line during floods and other high <br />water periods.
