New Algae Control Technology Installed at Williston Lake at Camp Todd
JUL 6, 2022 - On behalf of our Board of Directors, Leadership Team and Property Committee, and staff, Girl Scouts of the Chesapeake Bay is excited to share some updates about our efforts to control the blue-green algae growth in Williston Lake at Camp Todd near Denton, Maryland.
The Problem
For more than a decade, a specific type of algae has grown exponentially in the lake at Camp Todd, disrupting the ecological balance within the water by depleting oxygen levels, releasing dangerous toxins and causing bad taste and odors. Previous efforts to manage the algae growth using barley straw have proven to be ineffective. Without the proper equipment and methods to monitor and control the growth of algae, we have been forced to drain the lake each year, which comes at a financial cost to our council and a loss of opportunity for Girl Scouts and volunteers to take part in activities like boating, paddleboarding, and swimming.
Our Solution
Recently, Girl Scouts of the Chesapeake Bay extensively researched the various options to continue to treat the blue-green algae problem and decided to make an investment in two LG Sonic buoys. These buoys are floating, solar-powered platforms that continuously monitor water quality and utilize ultrasonic technology to effectively control harmful algal blooms.
- How does it work? Ultrasound waves create a sound layer in the top layer of the water, impacting the buoyancy of the algae. The algae sinks to the deeper, darker layers of the water and are unable to photosynthesise, effectively stopping overgrowth.
- What are the advantages of using this technology? The ultrasonic technology allows us to monitor and control algae growth in an environmentally-friendly, toxin-free way that is safe for our campers and staff as well as fish, plants, zooplankton and insects.
- How much does it cost? This technology comes at a significant cost. The research compiled by both GSCB and LG Sonic prior to committing to these buoys was extensive. With both our membership and the financial health of our council at the top of mind, our Board and Leadership Team decided to invest not just in keeping Williston Lake clean and safe, but providing water-based programming and training for members with confidence.
As of this message, our Girl Scouts are in the midst of the first summer camp session of the year at Camp Todd. Because of our investment, we have no doubts that they will get the chance enjoy all that Williston Lake has to offer.
As always, thank you for your support of Girl Scouts of the Chesapeake Bay. If you have any questions regarding the new algae control technology at Camp Todd, please contact Member Care at MemberCare@cbgsc.org.
