Lake Isabella Dam
Working together with the LIPOA, this page was created to serve as a central repository for all documents related to the condition and care of the dam. Below is a Document Center that contains past reports, inspections, and repairs done to the dam. The Lake Isabella Dam is owned by the LIPOA and the annual winter drawdown is done under the oversight of the Isabella County Drain Commissioner. The dam undergoes a state required inspection every three years, with the most recent inspection completed in December of 2022.
