Steve,
I only fished it once this year back in the spring during the morning before the rush of water was released from the Fife brook dam. At that point the flow was around 125cfs which made wading perfect. When they release water the flow gets over 1000cfs which makes wading difficult but provides anglers the opportunity to float it.
It looks like the water hasn't gone much below 1000cfs for the past week or so (for the entire day). Its tough to predict the flows. I use the two following sites. The first one is the forecast flow for the day and the second one is the current flow. I use the second one to compare how accurate the forecast was. The problem with the forecast site is that its only for today - you don't know what they're planning for the weekend for example. They have a pdf link for a calendar of releases but that isn't always accurate.

Anyway, with the flows the way they've been lately, I wouldn't go there unless you have a float trip planned. Harrison Anglers can guide you on one (I haven't had experience with them though) if needed.
I would plan a wading trip only once you start seeing the flows going from 125cfs in the morning, to 1000 around noon, back to 125 late afternoon, for several days in a row. That would give you good fishing in the morning and evening.
