Outflow will further increase to full powerhouse capacity (approximately 27,000 cfs) at 6:00 am on Thursday morning, June 11th. This increase marks the commencement of sturgeon flow augmentation operations for 2009. Flows will remain at full powerhouse for 7 days, and ramp down to 20,000 cfs for 5 days, 17,000 cfs for 5 days, and 15,000 for 5 days following 2006 BiOp ramping rates for flow reduction. Following the sturgeon operation, flows will be reduced to the summer steady flow of 6-9,000 cfs. Hatches are light but look for caddis in afternoons and always big, black flying ants this time of year. Fish are much more active with warmer temps.
