Red shading shows areas of Lake Anna under a Harmful Algae Bloom Advisory through August from the Virginia Department of Health. 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.

Sometimes algae rapidly grow out of control, or bloom. Fish kill and other lake observation information suspected to be connected with golden alga blooms may also be emailed to the department at [email protected]. Algae are microscopic organisms that can be found naturally in all types of water. A report must be based on current conditions - a report that documents a past condition (defined as greater than 48 hours in the past) will be rejected by VDH. Another strategy the LACA committees are recommending is water and sediment testing in order to determine the overall sources of nutrients.

It is too early to tell at this time what the impacts may be in Arizona. The conditions that trigger the rapid onset of a bloom are not especially well understood, but there are certain conditions that increase the risk. Golden alga releases unique toxins that affect gill-breathing aquatic organisms (mainly fish and clams). We still need to do testing on the hot spots, particularly on the streams feeding the lake. Phytoplankton, a small free-floating water plant, is considered the bottom of the food chain. The area was designated for a no swim advisory by the VDH, and additional tests were conducted every two weeks.

Development around the lake and its tributaries is a big contributor, but higher water temperatures contribute to blooms, and heavy rain can bring more pollutants into the waters. The golden alga, Prymnesium parvum, is a tiny, one-celled aquatic organism about the size of a human blood cell. A key finding in the assessment is that 80% of the phosphorous loading in basin 1 is driven by external sources in the watershed while only 20% of the phosphorous available to the aquatic biomass comes from internal loading (phosphorous stored in sediment). Keep children and pets out of the areas experiencing a harmful algae bloom and quickly wash them off with plenty of fresh, clean water after coming into contact with algae scum or bloom water. 522 Bridge downstream to the Lumsden Flats/Rose Valley Cove, NEW Lower from the Lumsden Flats/Rose Valley cove downstream to just before the confluence with Pamunkey Branch (at the Splits), NEW Upper from the confluence with the North Anna Branch & Pamunkey Branch (at the Splits) downstream to above the confluence with Pigeon Run (tributary along State Park).

The subcommittee has looked into other options to control the nutrient flow, including adding wetlands to the streams, but Marshall said that option is very expensive. The environmental conditions that support golden alga are broad, and little is known about the specific and complex conditions that allow it to gain a competitive edge over other species, or about what causes a bloom that results in fish kills. It was previously brought to a halt around Labor Day weekend. Early effects of the toxin are reversible if the fish can swim to a toxin-free area or an area of low toxicity. Basin 1 is fed by a watershed covering 113 square miles and basin 2 is fed by a watershed covering only 33 square miles. The report goes on to state that peroxide-based algaecides tend to be more selective for many cyanobacteria and leave no potentially harmful residue behind. Winter conditions are not favorable for other, common kinds of beneficial algae normally found in our inland waters, which likely gives the golden alga a competitive edge.

In a small pond or lagoon, many or all of the fish present may be killed if a bloom is not promptly treated and is allowed to spread across the entire water body. Rain washes these nutrients from lawns and farmlands, into tributaries, and ultimately into lakes. Until then, VDH cautions people to not fish, swim, or let pets in bodies of water that smell bad, look discolored, or have visible foam or scum on the surface.

Water Appearance: When golden alga becomes more abundant during a bloom cycle in a lake, the water begins to turn yellowish, yellowish-copper or a brownish, tea color. The alga is a rapid growing and resilient algae species, out-competing other algae for nutrients and thriving in a wide variety of environmental conditions. 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. Submit reports to VDH using the online reporting form within 24-48 hours of the algae bloom condition. Not surprisingly, swallowing the water or swimming in it also causes problems. Their website offers helpful information on golden alga and other harmful algal blooms. It not only serves as source of food for fish, but it also helps oxygenate the water. Warmer waters may allow the algal community to change, which can decrease a golden alga bloom. Learn how your comment data is processed. LACA understands that people are tired of studies and data collection but the state funding of 1 million dollars for a study on how to best mitigate the algal bloom issues on Lake Anna is a wise investment to ensure future expenditures are focused on the mitigation and prevention approaches that have the highest probability of success for Lake Anna.

If inhaled or swallowed, it can cause serious liver, kidney, and neurological problems that can be deadly. Blooms may occur a couple times a year, or not at all in some years. The shellfish from the impacted waters are not safe to eat, so recreational and commercial fisheries suffer. 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. Activities such as boating may continue with proper precaution in advisory areas. In some ways, this is analogous to thunderstorms on a hot, humid day, when there just needs to be a trigger to get the process going.
