Manatee River Watershed


General Information

What is a Watershed?

A watershed (also called a drainage basin) is an area on the land surface from which water flows or has the potential to flow to a common destination. Watersheds are naturally separated from adjacent basins by topographic 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.

Manatee County has six major watersheds, named after bays or rivers, and numerous subbasins, typically named after the creeks. One of Manatee County's major watersheds, the Manatee River Watershed, is located almost entirely within Manatee County. The county receives the majority of its potable water from this watershed. The following two watersheds represent the portions of the Manatee River Watershed that are the primary sources of potable water in the County. Learn more about watersheds »


The Manatee River Watershed is located within Manatee County and spans 351.4 square miles. The watershed contains 25 named lakes/ponds, 39 named rivers/streams/canals and 2 named bays/bayous.

    Air Quality Index

    Air Quality
    Air Quality and EPA's Air Quality Index

    The AQI is an index for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air. EPA calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. For each of these pollutants, EPA has established national air quality standards to protect public health. (From EPA's AIRNow)
