that powerplant is in boston,right on the salt.
its at the end of the reserve channel{black falcon cruise terminal}.
tough to fish,for security reasons. but i know there's a hole in the fence though.
the emilia earheart dam in somerville is a better spot.no sneaking in.plenty of parking too. its behind the home depot/curcuit city thats on rt. 93.
go way in the back past the yacht club and under the r/r bridge and your there. theres a bike path/soccer field for the kids to play arround in as well.
the bass are definitly there all winter.
i caught a 31" last march 24th.
try to catch a super dead low tide arround sunset.the bass don't have as much water to roam and they really stack up at low tide.
bring mud boots for low tide.
you can fish the fresh water side as well from the same spot.
good luck.
