First, the project is not a lake but rather a widening of the river through the most populated portions of the path of the river. The footprint of the project area was chosen for a variety of reasons – engineering, hydrology, and geography – all driven by Corps of Engineers rules regarding flood risk reduction and a Cost-Benefit Ratio. In many cases, local features were taken into account in the design of the project. For instance, the project was laid out so as to not take in Mayes Lake, thereby preserving that area for its existing purposes and improving recreational opportunities.
