2022 Annual Report: The Ecological Monitoring of Dam Removal Projects in the New York State Portion of the Great Lakes Watershed
This document reports on the 2022 barrier-removal monitoring results within the New York State (NYS) portion of the Great Lakes watershed and expands aquatic connectivity restoration efforts which began in the Hudson Valley region of NYS in 2016. During 2022, in-field monitoring sites included Black Creek at the Black Creek Dam in the Village of Mexico (Oswego County) and Little Salmon Dam on the Little Salmon River, also located in the Village of Mexico (Oswego County) [Figure 1]. During 2022, new monitoring locations were established at both sites and Year-1 pre-removal conditions were documented. The continuing goal of these projects is to evaluate the effectiveness dam removals have in restoring aquatic connectivity and improving biological and water quality metrics within their vicinity. Monitoring efforts allow project partners to understand the biological, habitat, and physical responses to dam removals and provide quantitative data to demonstrate stream improvement, while also setting realistic expectations for removal efforts in varying landscape context settings.
