Canyon Lake Alum Treatments Prove Successful in Managing Water Quality
Recent study reports results from lake study on alum applications

Lake Elsinore, CA – On-going studies, administered by the Lake Elsinore & San Jacinto Watersheds Authority (LESJWA), demonstrate a continued effort to keep Lake Elsinore in balance. Established to improve water quality and ecology in the watersheds, LESJWA seeks solutions to accomplish these goals. Recent study results conducted by Dr. Michael Anderson, Associate Dean at the University of California, Riverside, identified historical challenges plagued by the lake, as well as current lake water quality management programs and their effectiveness.

“An extensive set of field and laboratory measurements and long-term computer simulations have provided important new insights into Lake Elsinore,” shares, Dr. Anderson. “The results from the studies of Lake Elsinore provide a new understanding about the past historical factors affecting water quality, and aids in better understanding and guiding future strategies for attaining water quality goals.”

Included in the lake study, hydrological and climatic conditions were collected and evaluated, demonstrating factors that can vary dramatically and alter the lake over time. The data collected was used to create models to understand how the factors can affect lake levels and quality. With hot summer temperatures quickly approaching and a constant need to elevate water levels remaining as a concern, the lake is likely to experience a possible die-off of vital fish populations causing an ecological imbalance, as was witnessed last summer.

The lake receives recycled water from Elsinore Valley Municipal Water District; however, one critical factor studied was the lake’s salinity, as a result of the supplemental water source. Lake water levels, evapoconcentration, and watershed inputs all effect salinity concentrations, in addition to natural nutrients that flow to the lake, due to its location at the end of the watershed. High levels of salinity can impair sport fish and beneficial zooplankton reproduction. It negatively alters the ecology and water quality of Lake Elsinore. The key to minimizing high salinity levels requires significant circulation of lake water with outflows of high saline lake water leaving the lake as stormwater enters the lake.

Additional factors studied include increased concentrations of chlorophyll-a, green pigment tested in lakes to determine algae growth, and their relationship to the addition of recycled water to the lake. While the recycled water supplements did not demonstrate a significant correlation with an increase in chlorophyll-a, periods of low lake levels did show increased concentrations. There were slightly lower concentrations due to the recycled water additions.

“The complex hydrology of the region presents unique challenges in managing Lake Elsinore. These challenges will increase in the face of climate change that will raise temperatures, increase evaporative losses, and further increase climate variability in the coming decades,” states Dr. Anderson. “Application of numerical models offer valuable insights to the past, present, and future. Continued and creative efforts will be needed within the lake and the watershed to manage and help meet beneficial uses.”

The supplementation of recycled water to Lake Elsinore aids in preventing the lake from completely drying out. Aquatic life in the lake requires oxygen to survive. Microscopic bubbles of oxygen in water are known as dissolved oxygen, a critical element to maintaining healthy water quality. While the effect of the added recycled water supply on the mean dissolved oxygen levels are limited, the recycled water does provide an increased range of water column dissolved oxygen concentrations. This means that in certain depths studied within the lake there has been proof that the supplementation of the recycled water has contributed to an increase in dissolved oxygen levels.

Funding for these essential studies and projects, which help in the improvement and monitoring of Lake Elsinore’s water quality and ecology have been provided by a State grant, the Santa Ana Watershed Project Authority – One Water One Watershed (OWOW), and by the Lake Elsinore and Canyon Lake Total Maximum Daily Load (TMDL) Task Force, which consists of cities, the County of Riverside, agriculture and dairy coalitions, and other organizations in the San Jacinto River watershed.

Canyon Lake Alum Treatments Prove Success in Managing Water Quality
Recent study reports results from lake study on alum applications

Canyon Lake, CA – Residents of Canyon Lake recently witnessed the sixth application of alum to the main body, coves, and north causeway of the lake. With the support of the Lake Elsinore and Canyon Lake Total Maximum Daily Load (TMDL) Task Force that is seeking to significantly improve water quality and ecology in Canyon Lake, the applications have proven successful in minimizing algae growth.

Being that Canyon Lake is located near the end of the watershed, it receives high levels of nutrients, such as nitrogen and phosphorus, as a result of water runoff. These nutrients encourage algae growth. By adding alum to the water, it immediately binds to the phosphorus, causing it to neutralize and become inactive. This process was chosen as a means to improve lake quality due to its proven effectiveness in lakes throughout the country. Recently, a 3-D model of the lake was developed to better capture the complex hydrodynamics and water quality observed. The study has been monitoring the effectiveness of the alum treatments since 2013. Recent results demonstrate that levels of phosphorus have been consistently lower in the main body of the lake following alum treatments, as compared to 2009-2012.

Dr. Michael Anderson, University of California, Riverside Associate Dean, responsible for conducting lake testing shares that, “Control of phosphorus via alum has shown meaningful progress, although continued in-lake controls along with watershed best management practices are needed to further improve water quality. New 3-D modeling for Canyon Lake will provide greater understanding of relationships and unique water qualities of the distinct north, main, and east basins.”

Since 2000, the Lake Elsinore & San Jacinto Watersheds Authority has been conducting field studies, laboratory measurements and long-term computer simulations to provide new insights into the complex ecosystems and hydrology of the lake. In 2014, a two-day hydroacoustic survey was conducted to provide an assessment of the lake capacity. The survey illustrated that substantial sedimentation has lowered the capacity of the lake compared to 1993. The complex hydrology of Canyon Lake poses unique challenges in water quality and ecology management. Continued study and alum applications in the lake will take place in order to meet water quality targets.

Funding for the alum applications has been provided by a State grant, the Santa Ana Watershed Project Authority – One Water One Watershed (OWOW), and by the Lake Elsinore and Canyon Lake Total Maximum Daily Load (TMDL) Task Force, which consists of cities, the County of Riverside, agriculture and dairy coalitions, and other organizations in the San Jacinto River watershed. Implementation of the alum project is being coordinated by the City of Canyon Lake, the Elsinore Valley Municipal Water District, LESJWA, the TMDL Task Force, and the Canyon Lake Property Owners Association.

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.
