The Warner's Pond Dam Removal Subcommittee meeting held on November 11, 2024, focused on the ecological implications of the dam's removal, particularly concerning fish migration and habitat restoration. The discussions highlighted the importance of enabling cool water species, such as brook trout, to access upstream habitats that are currently restricted due to the dam.
One key point raised during the meeting was the misconception regarding temperature differences and their impact on fish passage. A participant clarified that while there may only be a 1-degree temperature difference, the primary concern is not temperature alone but rather the ability of fish to migrate freely. The removal of the dam is expected to facilitate this migration, allowing brook trout and other species to move between different habitats, especially during colder months when they typically retreat to headwaters.
The conversation also referenced insights from an OARS representative, who presented data on current cold water fish populations and their distribution. It was emphasized that the existing temperature conditions, even with a slight increase, would not suffice for effective fish passage year-round. However, the subcommittee members agreed that if a fish passage were established, it could potentially allow fish to migrate for a significant portion of the year, regardless of the dam's presence.
Overall, the meeting underscored the ecological benefits anticipated from the dam removal, particularly in enhancing fish migration and restoring natural habitats. The subcommittee plans to continue exploring these issues as they move forward with the project.
