Commissioned by the South Florida Water Management District as part of the Comprehensive Everglades Restoration Plan, the contract is to reduce harmful discharges into the Caloosahatchee Estuary in Hendry County by 2024.

It includes the construction of an earth-fill dam with a perimeter of about 26km and a separator dam of 4.5km in length. The reservoir will encompass about 40.5km² and store 209.7 million m³ of water when full.

According to the company, when it rains the reservoir will capture water run-offs contaminated by residential and agricultural developments in the area. During dry periods, it will maintain a desirable minimum flow of fresh water to the estuary, reducing extreme salinity changes.
