Dona & Roberts Bay Basin

The Dona & Roberts Bay Basin is located within CHNEP and spans 145.6 square miles. The basin contains 64 named lakes/ponds, 26 named rivers/streams/canals and 6 named bays/bayous. The basin connects one of the five major drainage basins in Sarasota County to the Gulf of Mexico via the Venice Inlet. Significant modifications have been made to the drainage basins, principally to the main tributaries. Many of the creeks have been dammed in order to inhibit upstream flow of salt water. They are also deepened or lengthened to allow better drainage. These have resulted in a complex sedimentation and erosion pattern with substantial anthropogenic influences.

This basin is located within: Dona & Roberts Bay Watershed

CHNEP's Comprehensive Conservation and Management Plan (CCMP) identified four action plans: water quality improvement; hydrological restoration; fish, wildlife, and habitat improvement; and public engagement. Click on the interactive maps below to view data associated with these goals and actions.

Water Quality Snapshot

The Water Quality Snapshot compares the most current water quality data to applicable water quality standards for Chlorophyll a, Phosphorus, Nitrogen, Bacteria, and Dissolved Oxygen to provide a snapshot of how a waterbody is doing. Water quality standards are outlined in Florida Administrative Code 62-302 for fresh/marine waterbodies of different types and uses. A Water Body Identification number (WBID) is an assessment unit that is intended to represent Florida’s waterbodies at the watershed or sub-watershed scale. The assessment units are drainage basins, lakes, lake drainage areas, springs, rivers and streams, segments of rivers and streams, coastal, bay and estuarine waters in Florida.
