Water Management Issues:

1.  The Western States Endurance Run was held June 23 and 24 this year.  However, only June 23 affected boatable releases.  The release schedule during this time was:
Sat, June 23:
5 am Begin ramping up Oxbow flow.
7 am Reach full load at Oxbow of 1000 cfs.
10:00 am Begin slow ramping down Oxbow flow.
10:30 am Oxbow flow at 800 cfs.
11:00 am Oxbow flow at 300 cfs.
11:30 am Oxbow flow at 200 cfs.
noon Oxbow at minimum flow of less than 200 cfs.

Sun, June 24:
5am Normal boatable releases resume, yielding 1000 to 1050 cfs from 8 am to noon.

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.
