Jordan Lake Algaecide and Phosphorous-Locking Treatment Study

In accordance with S.L. 2017-57, this trial project will be conducted at Jordan Lake in the Morgan Creek arm of the lake. The Morgan Creek area of Jordan Lake has historically exhibited effects of excess nutrient inputs, including elevated chlorophyll a and pH, and is currently listed on the U.S. EPA’s 303(d) list of impaired waters. Proposals for the combined use of algaecide and phosphorous binding products are aimed at improving water quality in this area of the lake. Evaluation of the project has begun through baseline water quality condition monitoring, and will occur at least monthly for the duration of the project according to study design. The project is conditional based on review and approval by the U.S. Army Corps of Engineers, the federal agency which owns Jordan Lake and its surrounding shoreline. Information on DWR monitoring results will be made available as data is collected and analyzed. Historical water quality data can be found in annual reports that are available on the division's Falls Lake and Jordan Lake Monitoring webpage.
