HI Guys
I have been thinking about this one for a few days now, and opinions aside
I think the advice is not such where to fish the river but how.
In the Spring the hatches are very specific both on the Don and elsewhere.
You get Large dark olives and March browns , olive uprights and iron blues, and some grannoms and stoneflies.
The hatches really are at midday for the species the trout target ,namely the upwings on the Don. So being on the river from 1100-1500 is about right to catch the hatch, but even on the best beats the hatches are localised to specific stretches of the water.
For example if you are after good trout in the spring i would look for a deepish riffle about 100-200yds downstream of a shallow fast stretch, when the hatch comes on, the March browns especially, start to hatch in the streamy water and get carried downstream, by the time they reach the riffle you are at they are either drowning,struggling to hatch, cripple or have flown away, this is where the best fish sit and pick off the flies at their leisure, This is where to fish.
Feature such as large rocks, trees,eddies will hold the fish although search the water for often the biggies come out into open water at the this time of the year.(they seldom do this in daylight for the rest of the year)
The LDO's are often found below this stretch in the glides or in among the march browns depends where you are. So the same spot will usually suit you for both species.If you find the LDO's then you will catch good fish.
Many of the Experienced trout guys on the river search the water by starting at the bottom of the beat in the morning and walking its length noting the spots like the ones i have mentioned.They will explore but rarely cast until the fish come on, and they will often wait at a spot till the hatch starts as it often only lasts for about 30min.They will fish the spot till the hatch stops and then exlore the river casting dries into likely spots or at the odd rising fish, this is a very successful technique and a must on the Don in spring when you never quite know whats round the corner.
The iron blues on the Don in spring are tiny so if the fish are rising to invisible flies this is likely to be it and a size 18 snipe and purple is great, this only seems to happpen on certain beats though, so is very localised.
The uprights start when the LDO's finish and the trout will take them out of habit but the fishing is never as good as when the LDO's are on the water.
Hopefully this helps, it will go for all the beats.
The other bits to try are Manar and Fetternear (which i think is accessible now) The river is a bit bigger here but has much perfect LDO and MB conditions and seldom gets fished for trout.
