The U.S. Army Corps of Engineers, in conjunction with Northern Sonoma County Fire Protection District (NSCFPD) and Santa Rosa Junior College, are planning to conduct a controlled burn training at Lake Sonoma’s Warm Springs Dam from Wednesday, June 1 – Friday, June 3. This event serves to help train firefighters how to conduct controlled burns, and to allow for mandatory safety inspections of the earthen dam. Periodic episodes of smoke may be visible each day during the training course.
