boats in ponkapoag pond?

Anyone know how to get a boat into Ponkapoag Pond? I know it says on this site that you can get it in on the western tip but I don't see a single road near it on the map except for Harrison Rd and I've already been down there and couldn't get in.

Any help?

The boat ramp is a little past Harrison Rd. Its right past the Jewish temple but u have to carry the boat to the water because the road is blocked off with posts.

is there parking there?

lots of parking and no gas motors.
The whole place is very shallow and weedy.
You're better off wading there. The deepest water is 6ft sand and weeds.
