Fain Environmental conducted stream surveys to collect data for the Grays Pond Reconnection Design project. The goal of the project is to naturalize the area to improve ecosystem functioning, especially for fish and beaver. We performed hydraulic and hydrologic modeling to support design. Fain Environmental and Smayda Environmental designed alternatives and prepared a preliminary design report. The report will be used in the final design of the restoration project.
