We were in Rana on the 16th and it was very dry after a week without rain. Only the main Fhuran Rising and the one above it were active. Half the party went and photographed the Great Northern Time machine - good results too using their LED floodlighting and time exposures - the rest of us baled the small amount of water in the dig and dug some more. That was a good weekend. The previous visit in January was one of the wettest with the Allt nan Uamh flowing the length of the valley, the dam overflowing, and no hope of passing the sumped dig. It's definitely not a recommended free dive.
Looking at the weather forecast for the NW over the last few days I'd expect it to be flooded again. It does slowly drain, but probably takes a day or two to do so. That might be improving as we dig further along the passage searching for the plug hole. Until we find it any trips into Claonaite Seven in wet weather might last a lot longer than you expect. Members have had a couple of narrow escapes when it has rained during exploratiosn in Two A's Chamber and they've returned to find the dam about to overflow - in one case after an absence of only fifteen minutes.
I'd recommend checking first with the GSG if you want to visit. Perhaps you could join one of our trips - and get in a spot of cycling! If you go by yourself first wait for a good dry day with no rain forecast after a dry day or two. You'll need a short ladder for the top of the entrance shaft (fixed ladders take you the rest of the way and cows tails could be useful) and SRT gear or 6m of ladder for the Black Rift pitch.
