Lake Champlain grey water issue

[Marthawjb]

My husband and I would like to cruise Lake Champlain this summer on our trawler that has no grey water tank. I have read that no grey water can go overboard. Does anyone have any info/experience with this issue? Thanks!

Lake Champlain is a no discharge zone. You can not discharge black water, meaning you must have a means to lock your y-valve in the closed position to prevent accidental discharge of your holding tank. If by grey water you mean the water that flows down your galley sink drain and out a thu-hull, that is permissible.

Greetings and welcome aboard the CF, Martha.

Yeah - difference between grey water and blackwater.

Sinks, showers, and cleanish bilge water: grey water and allowed to be discharged
Poop and Pee: blackwater and no discharge

I believe the holding tank to thru-hull must be physically disconnected while in the lakes,however,I have never heard of anybody being checked. Plenty of pump outs easily available.
