Henry’s Fork 6-30-12
Following is a note from the Henry’s Fork Foundation concerning the ongoing reconstruction work at Ashton Dam. In the meantime fishing conditions and fishing success should remain good.
Hi all,
At the Ashton Dam reconstruction project, they are having problems with the rubber seal over the upstream coffer dam coming loose, resulting in some additional sediment moving downstream. To fix this problem, they need to send divers down to re-anchor the rubber blanket. Since this work is being done next to the dam bypass tunnel, they will need to partially close the tunnel while they do the work. However, as this is peak irrigation season, they have to balance this work with downstream irrigation needs. The result will be some major fluctuations in Henry’s Fork flows below Ashton Dam throughout the day. Flows could fluctuate from 1200 cfs up to 3000 cfs, and this fluctuation may happen four times that day. Idaho Fish and Game will be monitoring things that day.
Bottom line, Monday July 9th will be a day you don’t want to be fishing below Ashton Dam.
