After mainly surfing most of the summer We're still pretty much waiting up here in Scotland, though EKC did luck out on a a higer than expected trip down The Etive at the beginning of the month: http://www.edinburghkayak.com/gallery/etive03/ p.s. Whats your favourite river? The river you would choose to paddle, if you only had one choice. The Guil, before the floods. UK, The Roy (or maybe the Gloy) |

Charlie,
Really interesting to see your local rivers. Am involved in WW kayaking in Nova Scotia (Canada, eh.). They seem steep and narrow from your photos.

Scotland's geography (i.e. it isn't really a big enough country) doesn't create any serious big water runs, though The Etive is probably not representative either, being at the steep and narrow end of the spectrum. There are a few 'bigger' water runs. The Orchy, a classic collection of III-V pool drop rapids peaks at around 100m3/s. The Tay carries up to 1000m3/s on paddled sections but is greade II/III (excluding Campsie Linn maybe?). And these flows are probably peakish, not regular levels. 100m3/s == 3500cfs I think. |

I guess the flow rates through the Grey Dogs and Corryvreckan, not to mention Lora, would put them up amongst the world's big water paddles. Maybe? |

Depends on what your definitions are and what you're looking for... In terms of sheer volumes of moving water you'd be hard pushed to beat the big tidal streams, but even the small constrictions they're passing through are pretty big compared to what's common in rivers so they're relatively flat if you're thinking of size in the Z dimension (I'm thinking turbulence size rather than physical drop, which will obviously be small). I think (ICBW) you get about 12 knots through the quick ones, and that's over a front a good 100m+ wide and deeper than your typical white water, so that's *vastly* more than the Tay will ever manage and that has the highest discharge of any UK river.

Hey Charlie, where did you get that flow data? I know the Tay is wide
and deep, but 1000cumecs seems too much to me. I've paddled a lot of big volume rivers and I'm sure the tay wasn't one of them ![]() To put it in context 1000cumecs is around 38000cfs - that's the sort of volume you might see in the salmon or snake or colorado. I'm not saying it's impossible so close to the sea, just wondering where the info came from? JIM Charlie wrote: "Mike Taylor" wrote in message ... Really interesting to see your local rivers.

If you look carefully there's one spike at over 1500cumecs. To put it in context 1000cumecs is around 38000cfs - that's the sort of volume you might see in the salmon or snake or colorado. 1000cumecs is 35,300cfs but then that's peak. The Colorado in the Grand Canyon has a suggest maximum paddling flow (AWA) of 100000cfs and I guess it goes a lot higher than that, and that's with dams holding it back. And at the opposite end of the water level spectrum, a wee trib o'The Etive... http://www.urchaidh.com/gallery/madsun/ |
