Through the rehabilitation at two key reservoirs, <br />UAWCD is preserving as much as 721 acre feet and capturing up to an additional 300 acre feet of water for <br />a total of 1,021 acre feet. <br />Future growth plans involve expanding conjunctive groundwater and surface water management <br />strategies. Releases from reservoir storage is used to offset impacts to streams from decreased recharge <br />due to reduction in groundwater levels from the increased number of wells in unincorporated areas. For <br />instance, from 2000-2003, UAWCD collaborated with the U.S. Geological Survey to study the sustainability <br />of groundwater resources in the Upper Arkansas River Basin between Buena Vista and Salida in a 149- <br />square mile area. <br />In 2006, the District asked the Colorado State Engineer for permission to use its available water in an <br />expanded area to meet growing market water needs. The Colorado State Engineer 2007 approval letter for <br />the District's substitute water supply plan filed pursuant to its 06CW32 application allows the use of all the <br />District's owned water sources for all its decreed augmentation market areas in addition to use of all these <br />water and storage sources in an expanded geographic region involving most of unincorporated Custer <br />County under a future blanket augmentation plan as well as in Chaffee and Western Fremont Counties <br />where it is already available. <br />Upper Arkansas Water Conservancy District (UAWCD) Page 4 of 52
