Case Study

Harvey Lake Rehabilitation

Comprehensive Engineering Services were provided for comprehensive management at Harvey Lake. Lake management and engineering design was based on survey and study of water quality, water depth, sediment thickness, runoff patterns, and geomorphic evaluations. Implementation included the conversion of 5,250 feet of eroded and degraded lake shoreline into natural, emergent wetland and mesic prairie habitat. Over 10 acres of riparian vegetation was converted from invasive shrubs into native plants, shrubs and trees around a 15-acre lake. LWC provided Design, Management, Grant Acquisition, Permitting, Bidding, and Construction Observation Services. Funding was provided in part by the U.S. Army Corps of Engineers. LWC's wetland design and shoreline stabilization techniques included re-use of on-site logs and construction of off-shore berms and slopes. Restoration included shoreline stabilization, wetland buffer, and native plantings. A recreational fishery with a walking path trail was provided for lake visitors. Wetlands provide habitat for endangered and rare species at the site including Black-Crowned Night Heron, Common Tern, and Osprey.
