Heavy rainfall and rising temperatures are raising concerns about water quality in Jacksonville's waterways, as discussed in the recent Jacksonville Waterways Commission meeting. Officials reported that salinity levels at Mayport are slightly lower than normal, while temperatures are high enough to potentially promote harmful algae blooms. Fortunately, toxin levels in the affected areas remain low, particularly in Duval County.

The meeting highlighted a troubling trend in manatee deaths, with five reported since June, bringing the total to 14 for the year. Notably, three of these were perinatal deaths, attributed to an increase in births as manatees improve in body condition. The commission is closely monitoring the situation, especially regarding a recent incident involving a manatee death linked to a flood lock gate at Queens Harbour Yacht and Country Club.

Commissioners raised questions about the impact of flesh-eating bacteria in local waters, with officials confirming that while the bacteria is present, it poses a risk primarily to individuals with open wounds or weakened immune systems. The discussion also touched on the availability of food for manatees, with reports of regrowth in submerged aquatic vegetation, which is crucial for their diet.

As the meeting concluded, the commission emphasized the importance of ongoing monitoring and public awareness regarding water quality and wildlife health in Jacksonville's waterways.
