Nutrient Revision to Total Maximum Daily Loads Underway by LESJWA

Lake Elsinore, CA – Recent modeling and testing results demonstrate that the work performed by the Lake Elsinore & Canyon Lake Total Maximum Daily Load (TMDL) Task Force and LESJWA has helped further identify the sources of nutrients, which harm water quality at Lake Elsinore and Canyon Lake, and also support ongoing efforts to reduce nutrient loading as reflected by lake improvements implemented since 2000. A landmark TMDL Revision and Update reflecting these updates is currently going through final review by the Regional Board.

“The revised and more scientifically defensible TMDLs are evidence that the efforts of LESJWA have made, and continue to make, reflect a positive impact to the watershed,” shared Mark Norton, LESJWA administrator. “We achieved what we set out to accomplish but know that there is more work to follow to adapt to continued drought cycle challenges. LESJWA and the TMDL Task Force have had to seek creative solutions to a complex situation.”

The Lake Elsinore & San Jacinto Watersheds Authority (LESJWA) was first formed in the year 2000 to improve water quality in the surrounding watersheds. Due to the area having a history in agriculture and farming, properties surrounding the lake and the upper watershed often create run-off that is nutrient rich. These nutrients flow into downstream lakes and pose challenges with water quality. As a requirement under EPA, LESWA formed a multi-agency task force to help meet the requirements of a water quality regulation called a TMDL back in 2004. The TMDL establishes a limit on the amount of nutrients that flow downstream and negatively impact lakes in the lower watershed. The goal is to reduce runoff and nutrient-rich sediment that can
often have negative impacts to our lakes.

Complying with all the requirements of the TMDL is not an easy feat. Back in 2004, following watershed  modeling, the collection of hundreds of water samples and analyzing of data, a TMDL was determined. Along with the TMDL, suggested methods and strategies to reduce the high nutrient loads were made. Over the past 19 years, LESJWA along with over 20 agencies, have implemented strategies to better refine nutrient loading and implement measures to improve water quality at both Canyon Lake and Lake Elsinore. These projects include the installation of an aeration system in Lake Elsinore, alum applications in Canyon Lake, a pipeline to transport recycled water into Lake Elsinore, fish removal and sediment removal.

2018 LESJWA Water Summit

As a member of our watershed, the Lake Elsinore & San Jacinto Watersheds Authority (LESJWA) invites you to the 2018 LESJWA Water Summit. Our watershed faces unique challenges that require action and agency collaboration to seek solutions for watershed management. The Lake Elsinore and Canyon Lake Total Maximum Daily Load (TMDL) Task Force is an active partner in improving watershed challenges throughout the San Jacinto Watershed. The Summit will feature information on how the TMDL Task Force has worked with the Santa Ana Regional Water Quality Control Board to implement watershed monitoring, mitigation projects, modeling and a variety of other solutions to meet TMDL targets.

Wednesday, April 18, 2018
9:30 a.m. to 1:30 p.m.
The Diamond Stadium – Diamond Club
500 Diamond Drive, Lake Elsinore Registration
$30 per person, lunch included

This year, the task force will complete critical revisions to the TMDLs. These revisions impact our watershed. Therefore, we highly encourage you and other key representatives from your agency to join us at this event to learn more about these TMDLs and how these revisions may affect our watershed, starting in the San Jacinto Mountains, traveling downstream through Canyon Lake and eventually ending in Lake Elsinore.

In addition, you will learn about lake accomplishments and possible future activities; the Lake Elsinore Advanced Pumped Storage (LEAPS) Project, a proposed hydroelectric facility; and future impacts of the TMDL on the watershed. A panel session will be included with representatives from the Santa Ana Regional Water Quality Control Board, Riverside County Flood Control and Water Conservation District and the Western Riverside County Agricultural Coalition who will discuss how agencies are addressing TMDLs and improving their overall impact on water quality.

The 2018 Water Summit will take place on Wednesday, April 18 , 20 18 from 9:30 a.m. to 1:30 p.m. (registration is at 9:30 a.m., the event begins at 10 a.m.). The event will be held at Diamond Stadium in the Diamond Club located at 500 Diamond Drive, Lake Elsinore, CA 92530. Registration is $30 and will include lunch. Register online  or contact Liselle DeGrave of DeGrave Communications at (951) 764-0865 or email directly at liselle@degravepr.com.

Canyon Lake Alum Application Public Notice – February 12-16, 2018

 

Announcement of Public Notice to Canyon Lake Community
Canyon Lake Alum Application, February 12-16, 2018

Click her for PDF version of Public Notice

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 February 12-16, 2018. Stormwater runoff carries with it high levels of nutrients including nitrogen and phosphorus that hurt water quality and threaten aquatic life. This dose will be the seventh 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 using local stakeholder 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)

• Thursday, Feb. 8 Pre-alum dosing monitoring
• Sunday, Feb. 11 Mobilize equipment/ boat inspection
• Monday, Feb. 12 Holiday Harbor 7:00 a.m. – 4:00 p.m.
• Tuesday, Feb. 13 Holiday Harbor 7:00 a.m. – 5:00 p.m.
• Wednesday, Feb. 14 Holiday Harbor 7:00 a.m. – 3 p.m.
• Thursday, Feb. 15 East Ramp 7:00 a.m. – 2:00 p.m.
• Thursday, Feb. 15/16 North Causeway Pending (late afternoon)

News Regarding Algae Bloom at Canyon Lake

Subsequent to the April Alum application, an algae bloom was observed in several coves.  As in the past, a press release was shared with the media indicating that the cause of the algae bloom in the coves was not the alum, and that the algae would likely dissipate over time. Below are a few articles that have been released regarding this event.

 

NEWS UPDATE AS OF 8/18/15: All coves in Canyon Lake are now clear of algae and are safe for swimming and recreation.
