Johnston Iowa - The majority of lakes and rivers within Iowa have seen unusually high water for this time of year. Saylorville Lake peaked at nearly 30 feet above normal on December 22 and has been falling about a foot per day since.
With cold winter temperatures closing in, ice will be forming on the lake. As the pool continues to fall, ice shelves and extremely slippery shorelines exist. If an ice shelf formed, there is nothing supporting the ice underneath. Use extreme caution along the shoreline and do not go out onto the ice.
