Scope of work: for water control structure removal and replacement at Big Island Wildlife Area, Marion County, OH History and Overview

Big Island Wildlife area is in a former wetland prairie where agricultural development has taken over. The primary management for this location is to restore wetland and grassland habitats. Wetlands have been a primary focus as they provide opportunities for the public to partake in recreational activities (i.e. birding, trapping, hunting, etc.) and areas for waterbirds to nest, feed, and loaf. Water levels must be properly managed as the natural fluctuation influences the activity of wildlife. Water control structures are instrumental for this process given their ability to control water movement across the landscape.
