Quabbin is a 20K+ acre reservoir NE of Springfield, MA, an area of 5 towns that was flooded in the late '30s to provide water for eastern Massachusetts. Northern end is Orange, MA and southern end is around Ware. There are no buildings, docks or anything on the shoreline. The lake is about 13 miles long and has restrictions, max hp 25 4 stroke, all boats must be inspected ($40.00) and 'sealed". If seal is broken, boat is not allowed back on lake. No Mass license needed, $5 per day fee plus a couple od bucks for parking. I buy an annual $25 senior pass that includes everything plus anyone in my car with me.
It is a fishermen's paradise especially during the spring. 2 years ago, one of our "crew" caught a 7lb 1 oz small mouth. No pleasure boats, PWC or general public to deal with, boat rentals available, three great state maintained launches. Just put Quabbin into a Bing or Google map search. There is a Quabbin website with all the details. It really is an under fished lake due to the hp and inspection restrictions. 75 smallmouth spring days are a norm. The only places that beat it in New England are some of the Maine lakes.
