"The best fishermen I know try not to make the same mistakes over and over again; instead they strive to make new and interesting mistakes and to remember what they learned from them" - John Gierach
Ok, we are in the jaws of a drought and one just has to look at the USGA map of Massachusetts to understand why. Virtually all of the river gauges are marked in red which signifies a low water condition. Now, does that mean that freestone fishing is over? No is the answer. Over the decades I've had great summer fishing on the Millers and the EB when flows were low but fishable. Early morning and dusk are the best times for this kind of trout hunting. Remember, fly fishing for trout is a self regulating activity. Trout feed the most heavily when the water temperatures are between 55 and 65 degrees. Above 65 they begin to slow down with less need for food. Also remember that browns seem to tolerate warmer water better than their cousins.
One thing you should avoid is fishing around tributaries!!! When main stems get really boney trout will seek out the tribs and stack themselves up below them. They are sitting ducks for blue herons (seen it), otters (that too), snaggers (ditto) and harassment from fly fishers. During real bad conditions, such as now, these may be the last resort for survival in some streams. That's why Connecticut and Massachusetts BAN all fishing within 100 or so feet of certain tributaries on the Housatonic from mid June to September, a very good idea that should be enforced on all our major trout rivers.
The Swift has been great!!!! Now, I haven't been north of Rt 9 since March and have no intention of doing so in the near future. The lower river has kept me occupied. There are some trout at the Pipe, good fishing at Cady Lane and Bondsville is wonderful. Fishing pressure has been very light but that may change on Friday, 7/1, when the regulations change from Rt 9 through Cady Lane. That is a traditional stocking date. We will see.
There's a chance of thunderstorms from Tuesday through Thursday which is usually a hit or miss situation. We need a REAL storm with 2 inches of rain to recharge things.
