    Recently there was long thread about the BCA. I can now post possible answers to some of the questions, such as "Why is the BCA still raising membership prices when there is a significant amount still left in its coffers?"

Mobile gravel slopes in sumps

I ve been thinking about the self filling gravel slope in the downstream sumps in New Goyden. This obstacle is obviuosly a major detterent to further exploration to the system. What techniques are available to us to make such a hazard acceptable?  I can not recall off hand the length of this slope in New Goyden, but a temporary measure I ve thought of may be ridged ribbed drain pipe; you know the sort blacck and ribbed on the outside(ffnarr) and blue liner on the inside. This cut into quarters lengthways and reassemled in situ with the aid of pre fixed brackets and C pins. If there is an area upstream out of the main flow the sections could be removed from the choke and anchored for future use. I appreciiate the immense power present in this system when in flood so the anchoring of the sections maybe not an option. If any suicidal bubble suckers out there have any thoughts make them know. This post may be more apt in diving, but infinate number of monkeys... LOL

That's just about the most difficult (and dangerous) kind of obstacle cave divers have to try and deal with. Remember what happened to Eric Establie at Dragonniere in Fraqnce not long ago? I'm just in the middle of something right now but I may send you a PM re your query later, in case it helps.

Steve Church (farmer) said 'whatever you guys have been doing down there it has been some good because Goyden is taking more water'. Asking him 'what makes you say that given we have more floods'. He replied that even though the flooding is worse it rarely gets on top of my track behind the farm now. My point is....(eventually!) it may be the gravel slope in New Goyden has been washed away and more water is travelling through the system. Let's hope that's the case and divers on the Big-Push (March?) can have a way open.

Very interesting Chris. If I recall correctly the gravel slope is the only major constriction in the system. Sounds very likely there has been a major change in there. Thinking about it, there is a constriction in the main streamway where the passage from Toad Hall meets the Nidd water. Think its New Goyden upstream 2 sump. This causes the water to overflow through Toad and on to Man Inlet sump in New Goyden. Any changes noticed in the lower reaches of Frog lately?
