Thompson Engineering managed a team of engineers, scientists, and technicians for the Watershed Assessment of Chaney Creek at Camp Shelby, Mississippi. Camp Shelby is a live fire training ground for troops preparing for deployment to Iraq and Afghanistan. The construction of the 1,500 acre complex, which required the cut and fill of approximately 10,000,000 cubic yards of soil, generated concerns about the potential for environmental damage downstream, particularly on Black Creek, a designated National Wild and Scenic River.
Thompson’s work included water quality monitoring; evaluation of sediment transport and deposition; watershed modeling; and biological and ecological assessments (including macro invertebrates such as crayfish and aquatic snails and ecosystems like wetlands and bottomland hardwood forests). Thompson also surveyed recreational users of Black Creek, and developed measures to alleviate post-construction issues.
The study was conducted in support of the National Environmental Policy Act (NEPA) compliance objectives. It provided environmental documentation for an Environmental Impact Statement (EIS) for continued military activities on U.S. Forest Service lands. In addition to consideration of effects from the live fire range construction, the assessment addressed impacts from future development and management of lands and natural resources at Camp Shelby.
