    This morning Cascade Township (the owner of the dam) posted the update to the Fall Drawdown on their website.

    The CTRA needs volunteers to:
    Document the exposed riverbed in front of your property on Saturday and Sunday (when water is at its lowest point)
    Describe the width and composition of the exposed river bottom (muck, sand, gravel, rock, mixed)
    Make observations of stranded aquatic organisms, especially freshwater mussels (commonly referred to as clams)
    Take photographs and counts of any stranded organisms
    Relocate any stranded organisms to the water
    Submit your information to and include:
    Your property address or area surveyed (if larger)
    Counts (even if your count is zero)
    Comments on any hardship from a 2 foot drawdown compared to our historical 4 foot drawdown
    Note: If you have any issues submitting your information via email please let us know and we will find an alternative method to gather your photos.
    Information you submit will be used to create a potential permit request with State of Michigan regulators, and if approved it may restore 4 foot drawdowns in the future. CTRA will work in close collaboration with dam owner Cascade Township on this effort.
