This document summarizes the findings of the April 15-16, 2013 workshop, focusing on the mean water budget comparisons for Phase I from 1985 to 2005. It includes analyses of precipitation, total evapotranspiration (ET), surface water inflows and outflows, groundwater inflows, outflows, and changes in storage. Key topics also cover cumulative comparisons of ET relative to precipitation, Platte River inflow/outflow dynamics, model verification (QA/QC), and assessments of watershed recharge and diversion demands.
