Roberts Bay Venice


located within Dona and Roberts Bay Watershed

General Information


Poised between Venice and Nokomis, Roberts Bay is a popular crossroads for boaters. The bay was named for Robert Roberts, who settled on its southern shore in the 1870s. The complicated flow of water in Roberts Bay comes from the Intracoastal Waterway, Lemon Bay, Hatchett Creek, Curry Creek, Blackburn Canal, Myakka River, Dona Bay, Shakett Creek, Cowpen Slough, and the Gulf of Mexico. Flushing to the Gulf is through the nearby Venice Inlet. Constructed several decades ago, the ICW, Blackburn Canal and Cowpen Slough modified water quality and natural systems in the bay. There is a small, legal discharge of highly purified wastewater from Curry Creek. This bay is an Outstanding Florida Water and part of the Charlotte Harbor National Estuary Program.

Bay Condition Reports

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 »

        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 »
