The season
What fills Cataract Falls, and when
Mill Creek feeds Cagles Mill Lake, Indiana's first flood control reservoir, but the falls sit upstream of the pool, so what comes over is natural rain-and-melt flow, hundreds of cfs in spring at the gauge upstream and a fraction of that by fall. The two drops and the 1876 covered bridge make it the state's flagship falls stop.
Typical best flow: March through mid June

What the agency itself says
In 1952, Cagles Mill Lake was built as Indiana's first flood control reservoir, protecting the Eel and White river watersheds. Mill Creek feeds the 1,400-acre lake and is home to beautiful Cataract Falls.
