After a slow start for foothill rain this season, the annual autumn decline of Folsom Lake has finally leveled off and the reservoir is beginning to fill again with wet weather forecast. Even with only light rain and a weak snowpack last month, Folsom Lake still begins 2024 at a healthy 112-percent of normal for this time of year, or 465,000 acre-feet of water stored. The average for this time of the season is roughly 414,900 acre-feet, officials said. After Folsom dropped to 410 feet above sea level Dec. 18, the lake stood at 412 feet as of Tuesday, Jan. 2, according to Lakesonline.com. One of the most misunderstood reservoirs in the state, Folsom Lake’s primary purpose is flood control, and can theoretically fill up three times a year (if the dam stopped releasing), authorities said.
