Jackson Project: Spada & Sultan River Conditions



From the City of Everett, 3/29/2018:

Notification of Portal 1 Shutdown for Sultan River Reach 3 Users

 The City of Everett is replacing Portal 1, an aging and deteriorated piece of critical water supply infrastructure. This work will require dewatering and shutdown of the tunnel and pipeline system to the Diversion Dam. The shutdown is expected to last two months, with June 15th as the target date for completion.

During the shutdown, required minimum flows in the Sultan River will be maintained by increasing flow from Culmback Dam. In-stream activities in Reach 3 of the river will be impacted by higher than normal flows.

We regret any inconvenience this necessary project causes to those who use the river.
