Fall Dam Drawdown 2023

Shoreline residents along the Indian River should prepare for the annual Fall reservoir drawdown, commencing November 1, 2023.

Otonabee Conservation will be adjusting water levels along the Indian River starting on Wednesday, November 1, 2023, by manually removing stop-logs at the following structures:

  • Hope Mill Dam
  • Lang Mill Dam
  • Warsaw Auxiliary Dam

During operations, shoreline residents can expect water levels to decrease above the dams and water levels and flows will increase below the dams. Water levels and flows will stabilize in the days following operations. In total, water levels will decrease 6 to 12 inches in the reservoirs.

Property owners upstream and downstream from the Hope, Lang, and Warsaw Dams should ensure that all boats, floating docks, etc. are removed from the water before this reservoir drawdown begins.

The Hope, Lang, and Warsaw reservoirs will not be restored to their current water levels until after the Spring freshet, which usually occurs before the May 24th holiday long-weekend.

Otonabee Conservation is your local, community-based environmental agency that protects, restores, and manages the natural resources within the Otonabee Region watershed. Otonabee Conservation works with its eight member municipalities to create a healthy, environmentally diverse watershed that improves the quality of life for residents, makes our area more appealing to visitors and new business, and helps to ensure a more vibrant regional economy.
