protection to the
Standard Project Flood (SPF) level, approximately an event occurring once in 935 years. However, investigations conducted in the 1980s and early 1990s of the dike system's potential seepage and stability problems resulted in the identification of two major areas of concern: the seepage and embankment stability at the culvert locations, and the problematic foundation conditions of the dike. During high water events piping is experienced thru the levee. In 1999, the Corps developed a plan to rehabilitate the HHD. The plan was approved in 2000 and divided the 143 mile embankment into eight reaches with the initial focus on Reach 1. This Reach by Reach rehabilitation approach has been replaced with a system wide risk reduction approach as required for safety modifications to dams.

A long term system was designed for the purpose of flood control, water conservation, prevention of saltwater intrusion, and preservation of fish and wildlife populations.

Over the years, issues with flood control around the lake have caused damage to the environment. This has also led to the recent algae bloom (2016) by preventing the natural flow of rivers from the lake to flush the algae out to sea. Decades of runoff from agricultural and other land uses have

In the 1930s, a larger system of levees was built around the lake. Following heavy precipitation and flooding from two hurricanes in 1947, the dike was again expanded in the 1960s to create the current
