Bounded by bridges between Siesta Key and Sarasota, Roberts Bay receives significant water from the large, urbanized Phillippi Creek basin. The adjacent Big Sarasota Pass flushes bay water to the Gulf. Extensive navigable canals and bayous on Siesta Key bring recreational boaters into this small, shallow bay that includes attractive undeveloped islands and mangrove forests. Two small, legal discharges of highly purified wastewater come from Siesta Key and Phillippi Creek. This bay has enjoyed the benefits of inclusion in the Sarasota Bay National Estuary Program, is an Outstanding Florida Water, and a SWIM waterbody.

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.
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.
