Thanks for the information. I appreciate any future updates as you hear things improve, as well. Sounds like our group should add the Mullica above Atsion L. to our list, as we love the upper Batsto. We are all using manueverable solo canoes, tight channels are a fun challenge!
To share what I've learned since posting: On Wednesday I phoned the Atsion office of Wharton State Forest. I was told, in short, that both the Batsto and Mullica rivers are designated "CLOSED" by the State Forest because they are still "too high", and because emergency vehicle access is not possible due to significant sand road damage (if a paddler should need to be rescued). I always assume I'm on my own "out there", but I guess the state has a liability concern if they can't rescue an ill, injured or stranded visitor. I didn't ask if they issue trespass citations/fines to violators of the closures.
I was told to check back weekly; the forest staff is in the woods every day evaluating and will reopen sections of the river to paddling as soon as access improves.
I just did the Oswego River on Wednesday. It was the only river open at the time and it was really moving fast (I flipped my kayak); however, the water level was receding and it should be very doable unless we get more heavy rain. I also did the Mullica above Atsion Lake about a month ago after heavy rains, putting in at Goshon Pond. It's cleared for a distance, but not all the way to Jackson Road in ATCO. Some heavy timber down so expect to do some liftovers if you take that route. Best advice is to call Micks (800-732-0793) or Bell Haven (800-445-0953) and they will give you the scoop on river conditions for the Mullica, Batsto and Oswego. Rt 542 at Basto has been closed (don't know if it's open yet) pending a bridge inspection. The bridge is intact but needs an inspection. This has prevented Bell Haven from picking up people at Pleasant Mills and Batsto Lake. In addition, I understand that the dirt road leading into the canoe launch area at Basto Lake was affected, so call Bell Haven for a status report. The Great Egg Harbor River above Lake Lenape may be another option. Call the Winding River camp ground for a status report.
