Yes, Echo Bay is a trout stocking location along with one other marina in your neighborhood, I forget the name but it is down in the other cove. The only trout stocking in the New Milford arm is at the boat launch at the New Milford beach but that is too close to the canal for the grass carp stocking.
Those three spots plus the Danbury town beach boat launch, the Squantz Pond launch on Candlewood and up in Sherman at the Holiday Point beach where we are allowed to drive across the beach into the water, are the six primary trout stocking locations.
In past years I took a stocking truck into Sail Harbor, the New Fairfield town beach boat launch, the causeway area to Candlewood Isle and I think we did the prison beach area once. Anyway, both trout and grass carp will wander to find areas they like so distribution should not be a problem after a month or so.
