Madison River Dam: 963 cfs Kirby: 1,670 cfs and falling Flows have been dropping as quickly as the river went up just a few weeks ago.  Only four days prior they were letting 1,580 cfs out of the dam, and about two hours ago they  dropped it to 963 cfs.  This will do a couple of things:  First, with less clear water coming out of the dam it should take a little longer for the upper river to clear.  Second, the reduced flows will help the water warm up a lot quicker than we anticipated, so we should start to [...]

Madison River Dam: 1,390 cfs Kirby: 2,280 cfs Another letter from PPL: A flow change was made at Hebgen today about 1:00 PM. The flows were reduced from about 1610 cfs to about 1400 cfs. This adjustment plus the rain should bring the project up to full pool over the next few days. Hebgen Lake is at elevation 6534.48 ft which is 0.39 ft from full. Inflows are estimated to be about 1600 cfs. The falling water and increased visibility must have flipped a switch because the nymph fishing on the Upper Madison has been great over the last few [...]

Dam: 2,650 cfs Kirby: 3,200 cfs and rising Another letter from PPL... Inflows into Hebgen Lake continue to be about 2615 cfs. To slow down the rate of filling the lake and account for potential rainfall forecasted for the next several days, two increases were made today. One at about noon and the second about 2:00 PM. The outflow was increased from about 2300 cfs to about 2670 cfs. Hebgen Lake is at elevation 6534.57 ft which is 0.30 ft from full. Fishing has been tough with the rising water, but once she stabilizes for a few days things should [...]
