As I mentioned, there MIGHT be parking on the north end in a very small parking area (it is not a lot, but spots on side of road), but I am not going hunting for a spot to be disappointed and left with no parking. There is a smaller reservoir near BC called Waban Hill Reservoir, and I saw in street view that they have signs posted there for No Parking 2 hours before BV football games.When I called the Cityside Tavern I was told you can park by the Reservoir for as long as you like. I thought she mentioned it was free. Getting a spot might be another story.
