2. The Tevis Cup was held August 4 this year. The release schedule during this time was supposed to be:
| Sat, August 4: | |
| 5 am | Begin ramping up Oxbow flow. |
| 8 am | Reach full load at Oxbow of 1000 cfs. |
| 11 am | Begin ramping down Oxbow flow to 250 cfs. and maintain a maximum of 250 cfs until 11 pm. |
| Sun, August 5: | |
| 5am | Normal boatable releases resume, yielding 1000 to 1050 cfs from 8 am to noon. |
However, the actual release schedule was different in several respects: flow peaked at 870 cfs, not 1000 cfs; it started dropping immediately; at 11am flows ramped up before ramping down to 250 cfs.
