Since 1978, the Snowmass-Capitol Creek Caucus has organized and directed a long series of initiatives to protect the ecosystems of Snowmass and Capitol Creek.  


Snowmass Creek, and its tributaries East and West Snowmass Creek, provide water for agricultural irrigation in the Snowmass and Capitol Creek valleys, including Wildcat Ranch, and the adjacent Brush Creek basin. The Creek is also the source of water for municipal and snowmaking water used by the Snowmass Water and Sanitation District and the Aspen Skiing Company serving Snowmass Village, the Brush Creek basin, and the Snowmass Ski Area. Virtually all water demands in the Brush Creek basin are supplied with water diverted from Snowmass Creek.

For more than 30 years, the Caucus has been committed to protecting healthy instream flows in Snowmass Creek, particularly during low-flow conditions that typically occur from December through March and occasionally in August and September. In 2012, the Caucus commissioned an engineering study, The Future of Instream Flows in Snowmass Creek (AMEC Environment and Infrastructure), to evaluate potential impacts to the Creek associated with future growth, climate change and water management practices.  (attach PDF of Exec Sum)

Over the past decade, the Snowmass Water and Sanitation District (the District) has made extensive investments in conserving water.  With the recent development of ZieglerReservoir and ambitious leak detection, water metering and incentive pricing, the District is doing a great deal to ensure that flows in the Creek are protected, particularly during the low flow winter months.


During late summer months, the biggest demands for water from Snowmass and Capitol Creeks come from irrigators.  The Caucus  produced “A Water User’s Guide for Protecting Flows in Snowmass Creek” to help our neighbors --- ranchers and gardeners -- understand the importance of adopting efficient water management practices to help protect the health of Snowmass Creek. We are now embarking on an effort to assess the conditions of Capitol Creek, and explore opportunities for water users to protect the flows and riparian habitat of that Creek as well.
