Flash Flood

There was tragic news earlier in the week about 9 people killed by a flash flood in Arizona.  They were enjoying a sunny day at a popular swimming hole unaware of the torrential downpour miles upstream.  Apparently the first anyone knew of the changing conditions was a rumble like thunder and then a wall of water came down the river and was on them in seconds.  As is clear from the video in the above link it is not only the water but the debris in the water that causes such tragedies.

People say the River Dart is a ‘flashy’ river though it is not immediately obvious how that can be.  Yes there are relatively big flood waters but normally from looking at data on the Environment Agency River Level Monitoring Site it looks like the levels rise and fall relatively slowly.

Flash floods do happen here: Lynton and Lynmouth in 1952, Boscastle 2004, Coverack last week, but are thankfully uncommon.

As far as the Dart goes yesterday brought what was a borderline flash flood as recorded on the above Env. Agency website.

Wild Swimming Still Pool

On Thursday evening I swam my usual twice up and down the 300m pool near Dartington.  The river chattered over the stones and was still perhaps an inch or so higher than the typical summer low after Tuesday’s showers and just touched the last of the steps near the swing which hangs 6 feet clear of the placid, clear water of the main pool.  I swam with a girl who had stopped off on her run, 2 boys were messing about with snorkels in the shallows by the sandy beach and the 2 girls were taking turns on the swing.

The forecast was for rain.

When it came it was torrential hammering deafeningly on the tin roof at work.  I had to go and take a look at the river.

Beneath the bridge the shallows and banks of pebbles where the heron had been stalking yesterday had vanished.  However, the water might be just an inch deep, a covering and with no marker there was no knowing.

At the pool though it is obvious the level is up about 4 feet if not more.  Tree branches drag the surface and the steps have gone along with the little step from which I dive and the concrete ledge is being washed over.

Stepping into the water at the edge of the beach it is waist deep where yesterday there were dry stones and I wade out to the trees where dark brown water slooshes around the willows.  The water here is however barely flowing, dammed into a little pool by trees and bank.  Walking back along the bank it is clear that in just a few minutes the level has risen to fill the hollow under the leaning tree trunk and back at the steps the ledge has gone.

The water in the enclosed corner stirs gently, there is less flow than in the mainstream on a normal day and I bob easily in the surprisingly warm water keeping place with just gentle flicks of my hands and feet but with nowhere to go there is no point in staying in longer than to take a few pictures and watch the world quite literally pass by.

Hauling myself out using the small tree it is clear the water is rising fast.  It has now breeched the last of the rock and the oak tree roots are awash leaving just a few inches of the tallest rock poking above the surface and even that get swamped once in a while.  As I dry off I see a tennis ball whisk by and several plastic bottles and a surprising amount of potential firewood.  A long heavy length hitches on some trailing tree branches hauling them down until the log is released and the branches spring back with a crash.  The log broadsides the next branches and sticks creating a dam and a noisy gurgle of water.

The last of the rock is finally covered and at the same moment the water catches the tail of rope at the swing and sets it dodging and rocking, the water pulls one end in, flips it up and the other end is dragged in.  That is a rise of 18 inches in 30 minutes.

What looks like a honeydew melon in terms of colour and size spins past.

I’d like to stay and watch (as it turns out the level will not peak for another hour and the monitoring station upstream shows another 10 inch rise yet to come) but instead I’ll come back in a day or too and look for the tide line of debris on the all but submerged fence beyond the vanished beach on the far bank.

More heavy rain is however forecast.

 

 

The Morning Menagerie

The warm weather continues.

A single day when the temperature gets into the upper 20s Celsius here is notable but we have now had 5 or 6 on the trot and today is set to best those again.  More remarkable is the lack of a breeze.  Geographically speaking the North Atlantic is just over there and then it’s 3000 miles of open water such that weather and wind is the normal order of the day.  But again, the day has dawned breathless.

Walking down the track through the redwoods I startle a squirrel which makes off with that zig-zagging tail flicking run they do to confuse predators and then claws a tattoo staccato on soft  bark and is gone aloft.

The river level is dropping day-by-day, so there is not even the usual chatter of the water to carry through the trees and stepping carefully down the tree roots to the bank the water is even more mirror like than yesterday.  Clearer too, that and I am 15 minutes earlier today so I am catching the sunshine that has not yet swung away from the rope swing, but shafts down into the deepest part of the river, picking out the scoops of golden sand between the dark rocks.  The smooth water slides up my leg as though I am pushing my foot through some sort of membrane.  Lazy concentric circles spread until the reflections begin to bounce back from the bank, colliding and jumbling the surface.

Birds flit and dart, a wagtail skitters down to the stones I have just vacated and jitters nervously almost as if it doesn’t actually want its feet in contact with the ground.  High above a seagull heads up river with a squawk, whilst a pigeon zooms fat breasted over my head away downstream.  The shallows by the rapids are filled with flitting fish.

The gaggle of ducks upstream by the shallows corrals and keeps a distance from my slow progress against the current.  Finally they divide, the 2 males are not in the least bit concerned and seem almost to be asleep just gliding away from me at the last moment.  Meanwhile the mother duck shepherds her flock of 4 well grown young to the far bank beneath an overhanging branch, she stands erect in the water keeping both eyes on me whilst the young are penned, but are otherwise nonchalant.   Close by a dipper stands perfectly still on a stone in the shallows of the splashing river.

The current sweeps me back to the pool where a solitary duckling, younger then the others I have just seen and still with ragged downy feathers, peeps forlornly.  One duckling on its own with no mother is not a good sign but she seems able enough and forages amongst the riverside plants.

Swimming back up to the top of the pool the male ducks still don’t care and mum and ducklings are happy to watch me sweep down in the current once more, this time floating on my back in the dappled sunlight.  Of which there is a lot less now.  Half an hour and the pool is now half in shade and the water is now dark and mysterious.

I have just picked up my towel when there is a splash by the bank nearby and a kingfisher flits onto a tree branch, adjusts its breakfast in its beak and then whirls across the water and into a tree on the far bank.  I continue to drip and watch.  The bird flits down to a log resting in shallow water and then begins an aerial ‘battle’ with a second, each darting from its perch to displace the other only in turn to be displaced.  They go round and round for a few moments and then shoot away downstream.

And so the day begins, heralded in by the 8 o’clock clanging of the church bell as I walk back to the car.

À bout de souffle

It is just about 7am as I take the bridge over the River Dart at Staverton.  The low sun casts long shadows, but even so it is apparent that the river level is still high after recent rain as the shoal of pebbles is fully covered by water.  As I walk down though the trees the sound of the river seems more urgent that usual and it cannot be the sound is carried by the breeze as there is none of that.

It is rare that there is not some breeze, today is that rare moment.  The water is unruffled except where the flow that is indeed at least a hand’s span up on summer ‘normal’ surges over rocks that have been unseasonably submerged.  Not a single leaf twitches, the rope swing hangs motionless and even the sunlight reflected from the water fails to dapple the undersides of the leaves.  Totally still and almost totally silent.

Diving from the rock there is very little light in the water under the tall oak tree but out in the middle of the river there is a sudden change from shade to sunlight which reveals the sand and pebbles out of reach of my fully extended toes.

The river bed has been changing in recent years.  There used to be a beach and the sand used to slope gently out into mid-stream except when it collected a coat of sunken leaves which bubbled when disturbed.  But the floods of 4 years ago and since have set in train a reconfiguring of the profile.  Some of the bigger logs were dislodged which exposed the longer buried more rotten wood and that has put up no resistance to the river.  Now the beach is barely 1/2 the width it was and beneath the water the edge is a vertical drop off into water deeper than I am tall.  What’s more the exposed face beneath the water is just more compacted twigs, branches and sand, so I expect the erosion to continue.

The water is chilly despite the sun and each time I breathe out I leave a thin, white cloud hanging above the water.

Climbing up the bank and looking back the river has been reset to ‘still’ and there is as yet no hint of a breeze so that all there is to tell I have been there are a few splattered watery footprints.

Goldilocks and the Early Morning Swim

‘Eeek, the river is too cold’, said the winter swimmer.

‘There are too many people’, said the holiday swimmer.

‘But that’s just right’, said Goldilocks walking through the morning sun patterned woods, the air pine scented by the redwood trees and elusively heard in the distance the patter of the river over the stones in the shallows heading down to the deep pool.

The water is mirror calm without the hint of a breeze and the flow is only given away by a few petals of foam carried down from the distant weir.  No people, just the chatter of birdsong, too early yet even for the first walker to have sent their dog in to smash the magic tranquillity.  That job is mine.

I am swim ready beneath the sweatshirt and shorts and my toes curl on the edge of the stones worn down by countless other feet, many of which have been my own.

It is called Still Pool, but only for another 1/2 a second.  Take sight of a little petal of foam, lift up on tiptoes, the water rushes at me and then everything changes from bright glittering sunshine to fiery orange peat filtered sunlight.  Down, down to the rounded pebbles, across the river bed, rising on the gentle slope of the far bank where sand  cascades amongst the pebbles.

Climbing back out on the diving rocks the water at my feet is now a jumble of conflicting ripples reflecting back from the banks, but upstream, fully half the distance of the 300m pool, serried ranks of ever diminishing ripples march onward against the flow.  And then the water is rushing towards me once again.

Early morning throughout June, July and August is the time to be here.  It is the only time that the sun sweeps its path across the river downstream where the forced gap in the trees allows light into the pool.  Swim upstream then float down under the leaning beech trees into the shallows.  The hazel tree that the kingfishers used as a fishing post has been carried away by a winter storm, though its future looked tenuous last year and the sandy beach on the far shore has been further eroded, there is less than 1/2 the area of even 3 years ago.

After 25 minutes I climb out again only to take two more dives from the rock but there is a distinct chill in my toes, it’s time to go, but it is almost no diversion at all to come here on my way in to work, I will see more still water before summer is out.
