Henry’s Fork 11-09-09

Fishing on the Henry’s Fork is still good. Look for Blue Wing Olives in the afternoon. Nymphing and Streamer fishing have been producing a lot of good sized trout as well. Keep and eye out for trout to start eating midges, below the surface and on top as we continue to see cooler weather.

We have been contacted by the Henry’s Fork Foundation and they informed us that they are making some improvements to the Box Canyon and the Riverside Boat Ramp and to expect these ramps to be closed for about a week.

We also received some information regarding Ashton Reservoir:

On Monday, November 9, 2009, we will be increasing outflow from Ashton Reservoir by approximately 200 cubic feet per second above inflow to the reservoir.  This will cause the reservoir level to decline approximately one foot per day.  We will be maintaining this rate through Friday, November 13, 2009, or until we reach Elevation 5147.  The reservoir is  presently at Elevation 5152.

Saturday, November 14, 2009, through Monday, November 16, 2009, the reservoir will remain at Elevation 5147.

Starting Tuesday, November 17, 2009, outflow will be reduced approximately 200 cubic feet per second below inflow to begin  refilling the reservoir approximately 1 foot per day. This will be maintained through Saturday, November 21, 2009, or until the reservoir reaches Elevation 5152.

During this time frame we will be testing generating equipment to determine its ability to operate at lower reservoir levels.
