Normal Water Level (NWL):the normal <br />elevation for a waterbody, typically <br />determined by a fixed structural outlet <br />elevation. <br />Ordinary High Water Level (OHWL):defined by <br />DNR based on elevation where the natural <br />vegetation changes from predominantly <br />aquatic to predominantly terrestrial. <br />2-, 10-, and 100-year High Water Elevations: <br />predicted highest water elevations for these <br />return frequency storms. <br />◦(approx. 882.5, 883.0, 887.0)
