Are you talking about the Swift in Belchertown? If you are then there are a few other options in the area for small stream fishing. The Deerfield, Millers and Westfield are all much prettier and generally less crowded options as well. I find the pressure on the Swift overwhelming and don't fish there - even when it was only 10 minutes from my back door. To me the place resembles an irrigation canal in the upper section. There are some fish in the Y pool, but not much until you hit the effluent pipe below the hatchery. Email me if you want a few other spots to check out in Western MA.
