COLUMBIA RIVER – John Day Limiting Spill Reduction Requests

Notice Number: 200935
Date: 06/08/2022 16:00 thru 08/31/2022 23:59

John Day Lock and Dam project is attempting to limit spill reduction requests from 6/8 -8/31. Mariners may still contact the John Day control room to request a reduction in spill. However, spillway flow reductions will not exceed 50 kcfs in any 30 minute period. If a vessel requires more than a 50 kcfs reduction in spill, they will need to wait an additional 30 minutes for the next change. The operators at John Day will need to provide BPA at least 30 minutes notice prior to any reduction in spill so it will be important that mariners provide as much advance notice as possible when they would like the reduction in spill. For additional information on this notice you may contact Aaron Marshall at (503) 313-3319.
