2007 1/1/2007 1/1/2008 The diversion canal (and juvenile fish bypass system) watered up on March 15. Josh Hanson, ODFW, informed us that the adult ladder is dewatered as of today, Aug. 31, and will remained dewatered until Sept. 3. Flows through the juvenile bypass outfall are scheduled to increase on Sept. 4 from the current 5 cfs to ~30 cfs. This morning, as a precautionary step, Josh removed the antenna from the juvenile bypass. He will redeploy the antenna on Sept. 4 after flows through the facility have stabilized.
