DNRC engineer Larry Schock sent this notice a few days ago:
The outflows from the reservoir will be reduced to match the inflows later this week on either Thursday or Friday. The current inflows are approximately 50 cfs and the current outflows are at 86 cfs..
 
The annual safety inspection of the dam will be conducted on Monday, 10/24, and it will require us to temporarily stop all outflows from the dam for approximately 1 hour so the outlet tube can be inspected.
 
In preparation for the shutdown, the outflows will be reduced to approximately 25-30 cfs on Sunday in order to allow the fish to temporarily move downstream and into deeper pools.
 
After the outlet tube has been inspected the outflows will be adjusted to match the inflows.
 
While there may be additional minor gate adjustments made over the next few months to maintain the outflows=inflows status, the gate adjustments associated with the inspection will be our last major adjustments until early spring.
 
Thank you for your time in attending to this matter.
