I&M to Raise Elkhart Hydroelectric Reservoir for Spring, Summer Operations

Indiana Michigan Power (I&M) will begin the annual process of raising the water level upstream of the Elkhart Hydroelectric Plant to its spring and summer operating level.

Starting Monday, March 16, the reservoir level at the generating facility on the St. Joseph River will increase by approximately six inches per day over four days. The reservoir will rise from 739.5 feet above sea level to 741.5 feet. The reservoir was lowered two feet in December 2025 to reduce ice buildup. The drawdown at the Elkhart Hydroelectric Plant was conducted in accordance with the operating license issued by the Federal Energy Regulatory Commission.

Those who live along the St. Joseph River, especially residents within eight miles upstream of the facility, should complete work or cleanup activities before Monday, March 16 along the riverbank.

The Elkhart Hydroelectric Facility has been in operation since 1913 and has a capacity of 3.44 megawatts. It is one of six run-of-river hydroelectric plants on the St. Joseph River that I&M owns and operates. "Run-of-river" means water passes through the generating equipment inside the facility and is then returned to the river. Combined, I&M's six hydroelectric facilities generate more than 22 megawatts of electricity - enough to power 15,000 homes per year.
