Long-Term Arid Region Reservoir Usability Evaluation due to Salinity Induced Degradation of Water Quality

Project ID: 22102
Principal Investigator: Neal Gallagher
Research Topic: Agriculture Water Supplies
Funded Fiscal Years: 2022, 2023 and 2024
Keywords: None

Research Question

Can management of reservoir inflow water quality allow Lake Meredith water quality to recover and allow the reservoir to be used as a drinking water source without blending with groundwater to reduce or prevent non-sustainable withdraws from the Ogallala Aquifer?

What are the major sources of salinity into Lake Meredith and what percentage of the salinity load are they contributing?

Does characterizing the salinity reveal difficulties in treatment and downstream impacts to residential water users?

Need and Benefit

Understanding salinity will inform current corrosion control procedures for source water users, inform future source water planning decision making and support determination of the long term outlook for reliance on Lake Meredith as a drinking water supply source. This research will address the need by gathering data and developing an empirical model to understand sources of salinity, and long-term reservoir water quality implications of current and historical reservoir inflow water quality.
