However, it is advised that people not eat fish impacted by a golden algae bloom. The discovery of the harmful toxins caught the area by surprise, as there had been no indication of problems prior to 2018. Explanation. But why, after nearly four decades without detection, has the HAB reared its ugly head? The persistent algae bloom problem resulted in. The golden alga, Prymnesium parvum, is a tiny, one-celled aquatic organism about the size of a human blood cell. Additional efforts are underway to manage the blooms. It was previously brought to a halt around Labor Day weekend. The LOWER and MIDDLE lake is monitored in the first week of each 3-week cycle The UPPER lake is monitored in week two of the cycle The Waster Heat Treatment Facility (WHTF) is monitored in week three of the cycle LACA plans to conduct eight cycles from early May through early November. Avoid discolored water or scums that are green or bluish-green because they are more likely to contain toxins. The 2022 bloom had a severity of 6.8.

The Virginia Department of Health (VDH) and the Virginia Harmful Algal Bloom Task Force, which includes the VDH, the Virginia Department of Environmental Quality, and the Old Dominion University Phytoplankton Laboratory, will continue to monitor water quality in the lake. DEQ and VDH received $3.5 million in the biennial budget to study harmful algal blooms in Lake Anna and the Shenandoah River, which feeds water to the Chesapeake Bay. Most of the documented golden alga blooms and associated fish kills occur during seasons when water temperatures are between 55-80 degrees Fahrenheit. A general rule of thumb used by environmental engineers is that one square mile of watershed management in developed areas costs $5 million to achieve a 20% reduction in nutrients. You can use Google Maps, or other mapping tools, to provide the latitude and longitude of the location. If tests are positive, additional testing will need to be conducted by either the Virginia Department of Environmental Quality or VDH, with VDH responsible for issuing the necessary advisories. Interested LACA members are welcome to volunteer in support of LACAs Water Quality Monitoring and Cyanobacteria Mitigation Programs. When necessary, the lake will be restocked with sunfish, bass and catfish. Email notifications are only sent once a day, and only if there are new matching items. Mike Rigdon, environmental preservation committee chairman of the Lake Anna Civic Association (LACA), believes the recent HAB outbreaks are the result of more testing on the lake and changes in the way the results are considered. LAAC issued a contract to SOLitude Lake Management for the research, data capture and analysis, assessment and recommendations. Field work was conducted between May 2021 and September 2021 consisting of sediment and water sampling and analysis. When lake water quality is satisfactory, fish stockings then resume. SOLitude referenced several models that are used within the research community for assessing lakes and other surface waters and documented their reasoning behind the use of the LLRM for this assessment. Their website offers helpful information on golden alga and other harmful algal blooms. The final report from the work was published in February 2022 and is available at this link. If you observe an algal bloom, ADEQ recommends: Another type of algae commonly found in Arizona is golden algae. Algae blooms may last for days or weeks. As the spring and summer season arrives, both groups are working hard to reduce the impact of potential outbreaks with early testing and notifications, as well as continuing to seek solutions to the problem. To date, golden alga has been confirmed in various public and private waters in the greater Phoenix area and in three reservoirs on the Tonto National Forest. As the planet warms, water temperatures climb and rain gets heavier, meaning the bloom risk increases. SOLitudes data showed that Basin 1 was well-mixed throughout the year and had sufficient oxygen throughout 2021. Sometimes algae rapidly grow out of control, or bloom. Get up-to-the-minute news sent straight to your device. If the discussion is about several species (or a group of species), then the term algae is used.

The environmental preservation committee has taken the lead on the issue and spent the past two years since the first outbreak networking with the three soil and water conservation districts, York River Watershed, various state and local agencies, state representatives, and community groups that operate around the lake. Swimming advisories have been issued for the following areas of the lake: Pamunkey Branch (contains changes from prior advisory, Lower added), North Anna Branch (contains changes from prior advisory, Lower added). This is a reservoir within the Salt River chain lakes and plays a vital role in power generation agriculture. The Lake Anna Bloom status reporthas been updated on the website under the quicklinks page of theHAB website.
