After a four year draught, Charles M. Hatfield agreed with San Diego City Council members to make it rain enough to fill Lake Morena Reservoir for $10,000. His rain enhancing tower and pans were erected south of this site, and Hatfield and his brother Paul worked diligently burning chemicals into the sky. Rain soon fell heavily, dropping 35 inches in one month on San Diego County. Two rainstorms in January 1916 brought great devastation, destroying Sweetwater Spillway, bursting Otay Dam, wiping out Otay Valley and Mission Valley, isolating San Diego, and killing 14 people. Hatfield hurriedly left town and was never paid by the city for his services, and Charles and Paul later went on to enhance moisture around the world.
