This email reports observed flows and demands as part of ongoing drought operations. A separate email will be provided with today's information for the annual drought exercise.
The National Weather Service reports that no rain fell in the basin in the last 24-hour period. There is a chance of 1/4 to 1/2 an inch of rain in the 24-hour forecast. The 7-day forecast indicates accumulations between 3/4 and 1 inch of rain is possible across the basin.
The Artificially Varied Flow (AVF) release from the North Branch reservoirs reached the Point of Rocks gage yesterday. Flow is currently just above 2,000 cfs, but we expect it to fall again unless it rains in the area.
Daily monitoring will continue over the weekend. If you are responsible for sending us daily withdrawals, please send them to coop@icprb.org by 8am on both Saturday and Sunday. (In addition, we will also need the morning and afternoon updates for the drought exercise.) Thank you!
