Lake Seminole Watershed
IMPORTANT NOTICE TO BOATERS
Mariners are urged to use extreme caution in the area of dredging equipment (booster pumps, pipeline, dredge barge, etc.), transit at their slowest safe speed to minimize wake, and proceed with caution after passing arrangements have been made.
Pipeline, work vessels, dredge barge, booster pump barge(s) and buoys will be visibly lighted and marked according to Coast Guard regulations and will be in the area until all work is complete.
Floating and submerged high density polyethylene (HDPE) pipeline associated with the hydraulic dredging operations of the lake will be utilized. Be aware that configuration and location of equipment can change daily.
Lake Seminole Aquatic Vegetation Management
Pinellas County Public Works is dedicated to the management of aquatic vegetation on Lake Seminole with the goal of enhancing habitat and promoting native aquatic plant growth. This is accomplished through cyclical lake-wide vegetation surveys and subsequent treatments by Pinellas County Vegetation Management. Pinellas County Vegetation Management provides treatments on Lake Seminole approximately every three weeks, depending on weather conditions. Aquatic plant management efforts by the county are only performed lake-wide for the treatment of Water Hyacinth, Water Lettuce and Hydrilla because of the invasive nature of these plants. Otherwise, we only perform vegetation management activities on county-owned areas of the lake.
The following are summaries of the current aquatic plant mangement efforts taking place on the lake. This section will be updated regularly, so please check back often.
Pinellas County Public Works is aware of the ongoing aquatic vegetation concerns on Lake Seminole and is using its knowledge and resources to best manage the lake. For concerns about aquatic vegetation on Lake Seminole, email email@example.com or call (727) 464-4425. Please include the location of the complaint, type of vegetation of concern, and your contact information.
Residents can also remove aquatic vegetation on their property. An aquatic plant management permit must be obtained through the Florida Fish and Wildlife Conservation Commission.
About Lake Seminole
Lake Seminole, the second largest lake in the County, has had poor water quality for many years. In 1991, Pinellas County and the Southwest Florida Water Management District (SWFWMD) partnered to complete the Lake Seminole Diagnostic Feasibility Study. This study showed that the primary cause of the lake’s worsening water quality was stable water levels as well as excess fertilizers entering the lake from untreated stormwater. In 2001, the Lake Seminole Watershed Management Plan was completed. The plan built upon the diagnostic study by further evaluating the extent of the problem and developing recommendations to improve the lake’s overall health.
Several projects recommended in the diagnostic study and the watershed plan have been completed. These include: the construction of an adjustable water level control structure, the design and construction of a new retention pond, the refurbishment of an existing stormwater pond, cattail harvesting, and two aquatic habitat restoration projects.
