TMWA Annual Storage Objective Determination (2016-2017)

Precision was hired by the Truckee Meadows Water Authority (TMWA) to develop guidelines to determine the drought storage reserves required to meet TMWA’s demands. The study developed methods to determine an end of year TMWA system storage target that would be sufficient to meet TMWA’s annual surface water demand if a significant drought occurs. The end of year system storage target is the sum of TMWA’s privately owned stored water and its upstream credit storage which is allowed under the newly implemented Truckee River Operating Agreement. The RiverWare° Operations model of the Truckee-Carson basin was used for this study.
