Little Sarasota Bay

Little Sarasota Bay


located within Little Sarasota Bay Watershed

General Information


This slender bay is central to the communities of Sarasota, Osprey, Siesta Key and Casey Key. Native people populated the area from at least 4000 years ago. The first settlers, the Webb family, built Spanish Point in 1847 and farmed there for decades. In 1983, the former Midnight Pass was closed, which reduced tidal flushing and changed the ecosystem of the bay. Today the Neville Preserve and Palmer Point Park are peaceful refuges in the vicinity of the former pass. Several creeks discharge to the bay, including Matheny Creek, Elligraw Bayou, Holiday Bayou, Clower Creek, Catfish Creek, and North Creek. There is a legal discharge of highly purified wastewater in Matheny Creek. Tidal flushing from the bay to the Gulf must go to either Big Sarasota Pass, the Venice Inlet, or both. North of the Blackburn Point bridge, a Manatee Refuge restricts boat speeds in the ICW channel to less than 25 m.p.h. The bay is within the Sarasota Bay National Estuary Program study area and is protected by degradation as an Outstanding Florida Water. It is also a SWIM waterbody.

Bay Condition Reports New!

Bay Condition Reports give a quick assessment of the water quality in a bay during a particular year by examining three important indicators of nutrient pollution: chlorophyll a, nitrogen and phosphorus.

    Watersheds and Drainage Basins

    Watersheds and Drainage Basins Icon

    Watersheds are areas of land with waterways that flow to a common destination. The boundaries between watersheds are elevated areas called divides. In this Atlas, the watersheds are composed of groups of creeks that flow to a single bay or group of bays. Drainage basins are subunits of watersheds and are defined by the main creek that flows through them. Sarasota County has five watersheds, named after the bays or river, and 28 drainage basins, named after the creeks. Stormwater improvements to reduce flooding and improve water quality are based on the drainage basin unit. Learn more about watersheds »

      Nautical charts show water depth, the shoreline of adjacent land, prominent topographic features, aids to navigation, and other navigational information. They are maintained by the National Oceanic and Atmospheric Administration (NOAA) and have recently been made available as geo-referenced, digital images which can be now be viewed within the Advanced Mapping Tool.

      Report Water Pollution


      Every one of us contributes pollution to our streams, lakes, bays and oceans. The wastewater, dirt, and debris of our lives eventually drains downstream. Each of us must minimize our contribution to keep our waterways healthy and enjoyable. Some materials are powerful pollutants like raw sewage, petroleum, or pesticides, but even natural, biodegradable plant materials can add nitrogen to water resources and cause algal blooms and fish kills. Please use the information below to assist you in reporting an incident to the correct agency. Learn More about Reporting Pollution »
