The dam stands at 22 feet high and spans 770 feet in length, with a maximum storage capacity of 327 acre-feet. It serves the surrounding area by providing water for irrigation, recreation, and general water supply needs.
Despite being rebuilt by the owner after a breach in 1996, East Lake Dam is not regulated by the state and has no current hazard potential rating. The spillway, which is uncontrolled, has a width of 164 feet and a maximum discharge capacity of 3,885 cubic feet per second. The dam is situated on the TR-Magnus Branch river and has a drainage area of 3.01 square miles.
East Lake Dam presents a moderate risk level according to risk assessment, but its condition assessment is currently not rated. The emergency action plan for the dam was last revised in 2011, and the dam has two uncontrolled outlet gates. With its rich history and importance for water resource management in the region, East Lake Dam continues to be a significant feature for water resource and climate enthusiasts to study and appreciate.
