Garrison Combined Reservoir Regulation and Power Production Order No. ST-1, 2011. This order will apply when referenced in the daily Reservoir Regulation and Power Production orders.

1. Powerplant shall have all available units loaded to the full capacity unless otherwise noted on order.

2. Supplementary releases shall be made at a uniform rate, to the extent practicable unless power units become unavailable due to forced outage, transmission loading relief, etc.

3. Unless notified by Water Management:

a. Daily average release: May be under run by no more than 1,500 cfs for the day.

b. Hourly releases: Do not exceed the scheduled daily average release by more

than 1,000 cfs for any hour.

4. Releases from the regulating tunnels should be adjusted as necessary to maintain scheduled releases (see 3a). Ex: If one unit is forced out of service, releases through the regulating gates should be adjusted within four hours to maintain the scheduled release. If two units are forced out of service, releases should be adjusted within two hours.
