Background reading: Lake Piru on Wikipedia
Lake Piru is a 494-acre reservoir in Ventura County, California. The water surface sits about 1,043 ft above sea level.
Water level on this page comes from USGS gauge 11109700 (Lake Piru near Piru CA). Wind, gusts and rain come from the National Weather Service forecast grid that covers the water.
On water this size, waves stay small even on windy days. The catch is gusts: shoreline terrain funnels the wind into sharp puffs that catch out small boats and paddlers. Reservoir levels move with releases and inflow, so ramps and beaches can change week to week. The water level page tracks that day by day.
The go or no-go calls above are a starting point, not a guarantee. Read how we score conditions, and always check local rules and posted warnings before you launch.
