Water Control Plans define normal operations of a water control structure and ensure the operations of a reservoir conform to laws and applicable federal regulations. On a periodic basis, these plans are updated to keep abreast of changing conditions, legislation and other relevant factors. Items taken into consideration during the revision process include Coralville Lake’s authorized project purposes of flood risk management, low-flow augmentation, recreation and environmental stewardship.
