This document summarizes a town hall meeting for the Colorado Basin Implementation Plan in Grand County. It includes an agenda with overviews of the Colorado Water Plan, challenges in the Colorado River Basin and Grand County, and breakout session topics. The document outlines concerns about declining reservoir levels, drought, and a doubling of population by 2030 without new water supplies. It also summarizes Grand County efforts like the Upper Colorado River Basin Study and Stream Management Plan to understand local water needs and protect flows. Challenges in Grand County include diverse water sources, lack of reservoirs, reliance on instream flows, water quality issues, and balancing future growth with seasonal demands.

15. Grand County – Upper Colorado
River Basin Study (UPCO)
 Investigated water quantity/quality in Grand (and Summit
counties)
 Developed tools needed to understand impacts of
diversions
 Supported negotiations among stakeholders
 Current/future water supply
 Reservoir level
 Instream flows
 Water quality
 Need for additional water supplies for existing and future
municipal demands
 Instream flows to support recreational uses and maintain
low-flows for water quality

16. Grand County – Stream
Management Plan
 80 miles of the Upper Colorado River
 Frame work for maintaining a healthy stream system
in Grand County - protect and enhance aquatic habitat
 Also protect local water uses and retain flexibility for
future water operations
 Identified
 Target flows
 Restoration opportunities
 Monitoring recommendations

17. Grand County
 Colorado River Cooperative Agreement
 Denver Water and West Slope partnership (34 parties)
 Framework for numerous actions to benefit
 water supply
 Environment
 Denver Water to provide Grand County
 Provide 375 acre-feet (ski areas)
 920 acre-feet Clinton Bypass Water
 Grand County Mutual Ditch and Reservoir Company – Vail Ditch shares
 Denver Water will not undertake any future water development
activities w/o prior approval of Grand County and Colorado River
District
 Assist in investigation/acquisition of Shoshone Power Plant by
Western Slope parties

18. Grand County Challenges
 Diverse water supplies (groundwater/surface water)
 No reservoirs (fens, permitting)
 Reliance on instream flows
 Water quality
 Future population
 Large fluctuations in demands – seasonal
 Complex water rights (exchanges, pumpbacks, etc.)

19. Agriculture

20. What are Others Saying?
 Need for multi-use/multi-benefit reservoirs
 Educate on true cost of water
 Land Use Policy
 Preserve urban boundaries
 Limit water use/outside irrigation
 Depletions not just demand
 Water Law Policy
 Address evaporation in municipal reservoirs
 "Use it or lose it" doctrine
 New water right should have to prove long term supply

21. What are Others Saying?
 Forest health and water quality
 Conserve water use in agriculture on a basin level
 Assess savings within the whole ditch system
 Incentivize agriculture
 Limit development

22. Breakout Sessions
 What are your top 5 biggest concerns?
