There are plenty of big smallmouth in Wachusett res. I have caught close to 100 of them in 20-21.5 inch this year. (total about 300 smallmouth caught/released at Wachusett res this year). The weight is not close to what great lake area or Canada region has. The heaviest one I caught this year was a 21 inch, 4 pound 9 ounce. I know someone caught a 22.5 inch weighted only a little over 5 pound. The length is there but not the weight. They are healthy looking but not super fat. I don't know why Wachusett smallies are kind of one pound less compare to great lake or Canada region with the same body length.
