WWA Activities

Water Rights and Climate Change Project
In many basins throughout the West, snowmelt is coming earlier than in historic times, prompting holders of prior appropriation water rights to demand water at an earlier calendar date than in the past.  This is obviously problematic for those rights defined in terms of specific calendar dates (associated with historic patterns of use), and may be even more troublesome for rights defined more generally (e.g., such as an “irrigation season” right), as this can have the net effect of increasing the diversion season and, thus, the size of the right.  This ongoing project (Summer 2007 to Summer 2008) will examine the extent to which this problem exists in Colorado and in a yet-to-be-determined Pacific Northwest state, where earlier runoff is much more pronounced than in the Rocky Mountain region.

Climate Workshops for Front Range Water Managers
Climate workshops geared towards municipal, state, and federal water managers, extension specialists, other policy makers interested in climate and water resources management. Topics include long-term climate trends and projections and potential impacts to water resources in the West, as well as seasonal forecasts and outlooks. WWA has an ongoing effort to host or co-sponsor workshops with water managers to develop and maintain two-way communication on needs for climate information by this sector and climate research and products.
