Lake Anna Deals with Harmful Algae Blooms by Irene Luck For over 40 years, Lake Anna has been a nearly pristine jewel in the Commonwealth's crown, except for a major hydrilla outbreak in the early 1990s and a fish consumption advisory due to heavy metals that was issued about a decade ago. The uncertainty created health and safety concerns among Lake Anna property owners and users, as well as captured the attention of the three county government bodies and both the LACA and the Lake Anna Advisory Committee (LAAC). The advisory committee has formed a science subcommittee, led by Spotsylvania County Supervisor Kevin Marshall, to lead its study on HABs. Harry Looney - July 2022 The Lake Anna Advisory Committee (LAAC) recently completed an assessment titled "Algal Bloom Assessment and Recommendations for Part of Lake Anna". Blooms are also increasing in brackish water and coastal locations, so the economic impacts extend beyond inland recreational lakes. 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. However, since the algae is free-floating, pinpointing the exact location proves difficult and ambiguous. The Sandbar station still had high cyanobacteria cell counts on the sampling date.
