Weeki Wachee River Submerged Aquatic Vegetation Restoration Project Maintenance Report for Month Nine
body
BRIEF OVERVIEW
The ninth monthly maintenance event for the Weeki Wachee River SAV Restoration Project occurred on February 10, 2026. The GrowSAV™ Herbivory Exclusion Devices exhibited light levels of biofouling, consisting mainly of settled sediments, filamentous algae and entrapped leaf litter. Sea & Shoreline biologists removed biofouling from the top and side mesh of the devices using stiff-bristled brushes.
There remains evidence of steady erosion around parts of the planting area, with more rapid erosion noticed on the outside bends of the river. If erosion continues to worsen, supplemental planting in areas that experience less water flow may be recommended. The supplemental planting units at site 5 will continue to be monitored and sediment inside devices will continue to be removed as necessary. Salinity data will be recorded at site 5 during the next maintenance event to determine if it is still a rate limiting factor to plant growth. Maintenance will continue for the next three months, with the next event taking place in March of 2026.
