The purpose of this letter is to follow-up on the request, via letter dated May 24, 2023, for longterm durable system efficiency improvement project proposals that result in water conservation benefiting the Lower Colorado River System and its water users. In that letter, proposals were requested by July 19, 2023. We are extending that deadline to August 18, 2023, to allow water users additional time to prepare project proposals. The LCB Conservation Program is intended to provide new opportunities to fund system conservation and efficiencies in the Lower Colorado Basin that lead to durable long-term solutions for the Colorado River System. These opportunities shall result in additional volumes of water remaining in Lake Mead. Please see the letter dated May 24, 2023, for eligibility requirements and proposal considerations.
