It’s a long way to the Sea, as it’s the upper headwater system of the Yorkshire Derwent, just below the Yorkshire Moors and there’s a tidal barrier into the Ouse, as it’s sealed off for drinking water abstraction, not sure if the Salmon ladder is still operating either, so doubtful.
There are a few big Browns too, as there are some deep holes in places, a little like the New Zealand creeks where you can get 20 pounders in streams just 6 foot across, but deep in places. The only possibility is, the Derwent can be diverted into a canal then into Scalby beck, which is short and runs into the Sea. This was cut in by Victorian engineers to stop Moors flash floods overwhelming the lowland areas, Seatrout run Scalby Beck and I’ve had a couple over the years in the Dove that were bright Silver - big tail and spent most of their time airborne on the end of your line- racing up and down the stream- unlike a Brownie.
We get two or three a year like this, either banked or break you clean off.
This is the largest I’ve managed to land, but they certainly get bigger, initially when they started showing up (not banked just leaping) folks thought they were Salmon, but I’ve never seen a Salmon, only these.
