The objective is to <br />document recent trends in snowmelt and runoff timing, and to quantify how those parameters <br />are affected by changing climate. Results will be used to estimate potential changes in runoff <br />amount and timing under a variety of climate change scenarios to understand possible <br />implications to water resources in Colorado including changes in water use, reservoir <br />operations, timing and magnitude of snowmelt flooding, drought response, and availability of <br />flow at certain times to meet instream flow rights. <br />
