Next week we will provide improved estimates for mid-summer flow rates and scheduled release windows. As a reminder, one of the Holm Powerhouse generating units will be out of service for repairs beginning on August 5th through the remainder of the season. August 6-7 will require both units to go down, however, valve releases will be made during this period to support adequate rafting flow rates.
