Public Notice Announcement – Canyon Lake Alum Application, October 11-15, 2021

Lake Elsinore & San Jacinto Watersheds Authority (LESJWA), is informing the Canyon Lake community that doses of alum will be applied to the lake in the main body, east bay and the area north of the causeway from October 11-15, 2021. Alum binds with phosphorus in the lake water, drops the nutrient to the lake bottom and thereby reduces algae growth in the lake.  Canyon Lake water mostly comes from stormwater runoff from the upper watershed each year that has  high levels of nutrients that hurt water quality and threaten aquatic life. This dose will be the 16th Canyon Lake alum application that has taken place. Alum, the method selected to provide the best results for Canyon Lake, has a proven track record of success and is safe to both humans and aquatic life. Drinking water quality will not be affected by any of the treatment options. Canyon Lake will remain open during the entire treatment process. Recreational users will experience little disruption during treatment application and implementation. In order to comply with water quality regulations enforced by the State, through the local Santa Ana Regional Water Quality Control Board, the Lake Elsinore & Canyon Lake Nutrient Total Maximum Daily Load (TMDL) Task Force, a coalition of cities, the county and several other organizations led by LESJWA, provides  funding to continue alum water treatments in Canyon Lake. The TMDL Task Force evaluated several options during the CEQA process and determined that alum application provides the best option as a step to effectively treat the entire lake in a timely manner with minimal impact to Canyon Lake residents. Alum Schedule (subject to change) Monday, October 11 Main Body 7:00 a.m. – 4:00 p.m. Tuesday, October 12 Main Body 7:00 a.m. – 4:00 p.m. Wednesday, October 13 Main Body 7:00 a.m. – 4:00 p.m. Thursday, October 14 East Ramp / North Causeway 7:00 a.m. – 4:00 p.m. Friday, October 15 Clean-up View the Canyon Lake Alum Application video View daily operational updates Download Public Notice Announcement PDF Additional Information Mark Norton Lake Elsinore & San Jacinto Watershed Authority Tel: 951-354-4221 Email: MNorton@sawpa.org

Fish restocked in Lake Elsinore to improve water quality

Lake Elsinore is being restocked with fish — the latest in continuing efforts to help improve the lake’s water quality and ecosystem. Early Friday, Dec. 4, the lake was stocked with bluegill, black crappie, striped bass and redear sunfish. The species were chosen after a year-long population study found that some types of fish — including channel catfish, largemouth bass, silverside minnows and mosquitofish — were overpopulating the lake.

Rains add six feet of water to Lake Elsinore, raising the lake to its highest water level in eight years

April showers will bring May flowers, and they have also caused the Canyon Lake’s Railroad Canyon Dam to spill over and send millions of gallons of water into Lake Elsinore. This overflow, caused by repeated days of heavy rains, has brought Lake Elsinore to a water level of 1244.85’, the highest since June 2012.
