Wetlands and Watercourse Surveys
As part of the 2012 upgrades to the hydroelectric facility, Nova Scotia Power (NSPI) planned to refurbish the existing dam and create a new spillway channel in a portion of wetland habitat. Initial stages of this project involved a wetland and watercourse survey at the site of the dam located on Donahue Lake, Guysborough County. A comprehensive functional assessment using the NovaWET methodology was completed in a portion of wetland habitat at the future location of the new spillway channel. Data obtained during the field assessments was used to support a wetland alteration application submission to NSE. On provision of an approval to alter the wetland, Strum was retained to identify potential wetland compensation options at the Donahue Lake Dam site. Strum consulted with NSPI and NSE to identify the preferred compensation option and developed a design plan to expand the habitat of an existing, on-site wetland. The expanded wetland will incorporate additional treed swamp habitat, as well as the creation of a vernal pool, which will provide habitat for the colonization of different plant species and refuge for wildlife. Project construction is currently in progress.
