Interim Update: When there are changes that occur either through lessons learned from spills and drills or other types of changes, we update only sections of the plans that have changed. Once the plan has completed a full review and these updates are incorporated into the new version, this list will be updated.

Please replace your current versions with the following interim updates:

Middle Columbia River – McNary Pool

Snake River – Lower Monumental Pool  SA-SLOMO-41.75R | BL-SLOMO-41.75R
