Water Quality Report reveals rising algae blooms in Jacksonville's waterways

In the heart of Jacksonville, the Waterways Commission convened on June 12, 2025, to discuss the current state of the city’s waterways, revealing a mix of normalcy and concern. As the meeting unfolded, officials reported that water levels across the region have stabilized, returning to what is considered normal. Salinity levels, crucial for the health of aquatic life, were noted to be within expected ranges, with measurements at Mayport showing 33 parts per million and Dames Point between 12 to 15 parts per million.

However, the report also highlighted troubling signs. Algae blooms have been detected in several areas, raising alarms about potential toxins. While microcystin, a harmful substance produced by certain algae, was found in Doctors Lake, officials reassured that no toxins were detected at other sites, including Shands Bridal and Mandarin Point. The presence of microcystin in Doctors Lake, with levels recorded at 4 and 5 micrograms per liter, is particularly concerning for local ecosystems.

The meeting also touched on the state of manatee populations in the area. Despite a total of nine manatee deaths reported since the last meeting, including one from a watercraft, the numbers remain low compared to previous years. A recent aerial survey revealed approximately 42 manatees in the county, a stark contrast to the 189 counted in 2024. Statewide, watercraft-related manatee deaths have risen to 47 this month, a worrying trend for conservationists.

As the meeting transitioned to public comments, the community's engagement with these pressing environmental issues became evident. The discussions underscored the delicate balance between urban development and the preservation of Jacksonville's vital waterways, leaving attendees with a sense of urgency to address these challenges head-on.
