Shark River Slough serves as the main artery of water flow into the southern Everglades. Historically, 60% of annual flows entered the slough along its northeastern reaches on the way to the coast. Completion of both the Tamiami Trail and elements of the Central and Southern Florida (C&SF) Project drastically changed the manner in which water now moves south-- shifting the majority of distribution to the west and leaving Northeastern Shark River Slough unnaturally dry.

In an effort to return a more natural hydrologic pattern to the area, construction has begun on a 1-mile bridge along Tamiami Trail, and an additional 5.5 miles has been proposed. This CESI-funded project established 30 permanent ecological monitoring sites in Northeast Shark River Slough intended to provide baseline data in advance of restoration activities. These data were also used to select a suite of response indicators to gauge the effects of restoration on ecosystem health.
