The assertion that the ' historic shift' in the way that \Wye catches have moved primarily in favour of the lower river is not of course entirely due to river flows. We all know that the Wye now rises and falls much more rapidly than it used to in the past, not totally due to abstraction but to the increase in upland drainage.
Whilst river flows are essential for fish movement to the upper river the other factor restricting upper river catches is of course the loss almost entirely of the very early spring run. \These fish took advantage of winter and spring flows which usually, but not always in the case of an extreme drought early in the year, took this major run of fish through to the beats up above Newbridge by the old opening date of 26th January. Lowest beats never usually got going until late April, May and June by which time most of the middle and upper river were well stocked and took the bulk of their catches then until they fished again in the Autumn.
Only in years of continuous high water did the upper river EVER fish well in the period after mid June. Many in fact never bothered to fish at all during these summer months. Several Erwood beats saw this effect last season!
We are now facing the scenario of the highest winter flows ever and as such there should, if there is any comparison whatsoever to the spring run of the past, be fish well up to Newbridge in considerable numbers.
There is no excuse if they are not -other than the fact that they no longer exist. Many times in the past the rod catch before the end of March/April exceeds the present whole seasons rod catch.
With river levels at least starting to settle at last anyone fishing above Hereford next week should in theory, if all the 'improvements we are told about are fact, do so with the utmost confidence. Will it happen? I'm not holding my breath quite frankly.
All the water that has been and gone this season will be for nought if we get a dry spring and summer. The lower river will clean up again under these conditions as they always have and always will.
I suspect whatever measures are promoted on the Wye by this report the effect will only be minimal until the upland sponge is restored and some of the drainage work is reversed. Some of us beleive too that some of the WUF river clearences have exacerbated faster run down of tributary levels. The Ithon has always run with heavy colour in spate and so has the main river below Hay on Wye notwithstanding the increase in poor agricultural practices. Despite saturation of the catchment for months the river levels now drop dramatically, often by several feet overnight. This has nothing to do with abstraction but it severely restricts the amount of running time available to fish entering the lower river and bound for the upper beats.
I wonder too if the EA are still having to approve abstraction and discharge licences to Farmers and to Industry on an almost weekly basis. Of course they are. We used to be able to object to the licences but we no longer know where and when they are being enacted.
Still uncertain just what conditions may be on opening day but level;s are somewhat better than they have been but a week is a long time in British weather and the question as to whether those early msw fish are still around in any numbers might yet have to wait a little longer to be answered.
