Lake Sumner and Dam daily Sumner and VCP ESA Release af daily Time Series Data

Daily time series for modeled Sumner plus Vaughn Conservation Pipeline (VCP) release for Endangered Species Act (ESA) compliance in af. ESA requirements below Sumner include gage targets for the Taiban and Acme USGS gage, with targets varying depending on how dry the year is. Results were modeled using the Pecos River Operations Model (PROM) for the purpose of the Pecos River Basin Study. This study used data from five downscaled and bias-corrected Global Climate Models (GCMs) run through a Variable Infiltration Capacity (VIC) hydrological model. Outputs at key headwater and tributary gages were then used as inputs and run through a RiverWare operations model, PROM. There are ten runs for each GCM which includes: a baseline run, five alternate management strategy runs, and four water footprint runs.

March 2020 Most Probable 24-Month Study

The Most Probable 24-Month Study report describes projected operations and power generation for Colorado River system reservoirs including Fontenelle, Flaming Gorge, Taylor Park, Blue Mesa, Morrow Point, Crystal, Vallecito, Navajo, Powell, Hoover Dam - Lake Mead, Davis Dam - Lake Mohave, and Parker Dam - Lake Havasu. Operations were projected using Reclamation’s 24-Month Study RiverWare model with the Most Probable unregulated inflow projections provided by the National Weather Service’s Colorado Basin River Forecast Center. The Most Probable inflow scenario reflects a median hydrologic condition which statistically would be exceeded 50% of the time. The operations depicted in this report reflects the Annual Operating Plan as approved by the Secretary of the Interior.
