The Berkshire County entry here is Mount Williams Reservoir, in Massachusetts. The water sits 1,037 feet up. The water covers some 49 acres, so pick a bank rather than trying to cover it all. Shoreline comes to about 1.0 miles, small enough to learn in a day. By elevation it is in the upper part of our Massachusetts listings. The town to know is North Adams, 2.6 miles out. After that come Williamstown at 3 miles and Adams at 4.7 miles. The county edge is within a short distance of the bank.
Open data we checked carries no depth for this water. A reservoir gives you a hard edge, a shelf, and not much else. The old creek line under the surface is the feature worth finding. County-wide records name brown trout, pumpkinseed, largemouth bass and brook trout. The list covers the county rather than this water alone, so treat it as a guide. On Mount Williams Reservoir the first feature you find is usually worth a session.
On the long-term average, July reads 67°F and January reads 19°F. The year splits cleanly: hard water, then open water. Winter locks it down, and early April brings it back. Ice clears near early April and comes back about mid December in a typical year. The shoulder weeks of the open season are the productive ones. Anyone fishing Mount Williams Reservoir regularly works to that calendar.
Ownership and access are not documented in what we hold. There is a car park half a mile from the bank. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. A landowner's word beats anything printed elsewhere. Rules for boats are stricter than rules for the bank in many places. Williamstown Reservoir at 0.8 miles is the sensible second choice. The position on Mount Williams Reservoir is worth confirming on the day.
