Pine Island Sound Basin

The Pine Island Sound Basin is located within CHNEP and spans 374.9 square miles. The basin contains 47 named lakes/ponds, 13 named rivers/streams/canals and 5 named bays/bayous, including Matlacha Pass and San Carlos Bay. Pine Island Sound receives tidal flushing from nearby Boca Grande, Captiva, and Redfish Pass, and contains the Pine Island Sound Aquatic Preserve. Matlacha Pass and Aquatic Preserve (divided from Pine Island Sound by Pine Island itself) and San Carlos Bay are influenced by inputs from the Caloosahatchee River and Punta Rasa Pass to the south.

This basin is located within: Caloosahatchee 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.
