2020-2040 Water Resource Plan

Since 2001, Truckee Meadows Water Authority (TMWA) has continually updated its Water Resource Plan (WRP) to analyze future conditions and to outline strategies to meet the region’s drinking water needs. From the lowest snowpack year in recorded history (2015) to the wettest water year on record (2017), TMWA has effectively managed its water resources to provide a resilient and reliable water supply for the region.

Diligent planning requires an analysis of a broad range of future conditions. Accordingly, the 2020-2040 WRP incorporates climate and population scenarios that effectively stress test the community’s water system for the next 20 years and beyond.

To adapt to changes over time, the WRP is updated every five years. This current version—approved by TMWA's Board of Directors in October, 2020—is the result of a from-the-ground-up redesign and has incorporated extensive customer feedback to help make it as useful and accessible as possible.

Of the customer insights collected, the top concerns were related to two topics: population growth and extreme climate variation. TMWA's approach to these issues are woven throughout this plan.
