Lake Seminole in Pinellas County spans 684 acres, making it the second-largest lake in the county. Created in the late 1940s by impounding a portion of Long Bayou during the construction of Park Boulevard, this manmade reservoir has transformed from what was once a brackish water extension of Boca Ciega Bay into a freshwater fishery. The lake averages 5-6 feet in depth and stretches just over 3 miles long. Its watershed encompasses 4,160 acres with multiple tributaries flowing into the lake before exiting through a weir at the south end into Long Bayou. Despite being situated in an urban area, the lake supports diverse wildlife including over 50 alligators, herons, egrets, ducks, pelicans, and various other waterfowl. The abundant aquatic vegetation, including hydrilla, hyacinth, pepper grass, and milfoil, provides excellent habitat for baitfish and gamefish alike.
