Iceman,
Personally, I haven't done much night fishing at Potholes, but have found the guys are Mardon resort to be very helpful with what's working and where the fishing is good. They can probably answer your question. If you haven't checked out their website, they have a weekly fishing report on their website that is also good (www.mardonresort.com).

I've done well using a bobber right off the dock (for trout and perch) and done well walking along the rock face of O'Sullivan dam casting for small mouth. The trout seemed to bite at all times of the day, but the small mouth fishing was best from early am until about 10:00. If you have a boat, there are lots more places in that lake that have great fishing.

I'm headed over for the 4th and will report on how it was and what worked for me.
