I&M to Raise Reservoir Level at Elkhart Hydroelectric Plant

March 14, 2023

ELKHART, Ind., – On the first day of spring, Monday, March 20, Indiana Michigan Power (I&M) will begin raising the water level upstream of the Elkhart Hydroelectric Plant, which is located on the St. Joseph River. 

Elkhart Hydroelectric Plant

The reservoir was lowered two feet in December 2022 to reduce ice buildup and flooding upstream. The reservoir will slowly be raised to its spring and summer time operating level, approximately six inches per day, over a three-to-four-day period. Those who live along the St. Joseph River, within eight miles upstream of the Elkhart Hydroelectric Plant, should be aware of the change in water levels.

I&M runs the Elkhart Hydroelectric Plant in accordance with its license issued by the Federal Energy Regulatory Commission. The Elkhart Hydroelectric Plant has been owned and operated by I&M since 1913. It is one of six run-of-river hydroelectric plants on the St. Joseph River. “Run-of-river” means all the water goes through the generation equipment inside the hydroelectric facility before the water is passed out of the facility and returned to the river.

Combined, I&M’s six hydroelectric facilities generate more than 22 megawatts of electricity – enough to power 15,000 homes a year.
