Plunker,

Although nothing is firm yet, more flexible operations at Lower Baker powerhouse are in the works. Unfortunately, it won't be ready and on line until 2012 as presently estimated. The powerhouse will have to undergo a major remodel, with two new smaller turbine units and generators installed. The plant will then be able to run perhaps as low as 500 cfs to 1500 cfs when the big unit isn't running. We're contemplating a higher minimum flow of 1,000 or 1,200 cfs, quite a jump from the existing 80 cfs. Hydrologic modeling is nearing completion, but engineering for the change and upgrade probably won't begin until 2008.

We're stuck with the lack of flexibility at the plant for a few years yet, but the long term changes should improve conditions for both fish migration in the lower Baker, and most importantly, spawning and incubation conditions in the Skagit when it is at low flow.

Sincerely,

Salmo g.
