Lake Kilarney is a private community lake. It would be advisable to get permission from a local landowner before trying to put in on the lake. In the previous mentioned video, we were lucky enough to have a fellow MWA boater with good connections. I’ve heard of putting in upstream of lake and paddling across, but it’s quite a bit of extra work.
One more bit of advice. The MWA is a pretty friendly lot. If you want to paddle the Saint for your first time, I would try finding some other MWA members that would be willing to paddle down with you. If you take a swim you will have extra help to gather your boat & gear. Just be sure to be frank and let people know your experience so they know what they’re getting into.
If D bridge gage is above 0″, there’s a good chance someone will be boating. Post your intent on this website and hope for some paddle partners!
