A “larinier” – a fish pass, allowing salmon, sea trout and eels to overcome the change in water level above and below Holbury Mill – has been installed where formerly there was a fish stew. It is working well. Trout have been seen swimming up the pass. Salmon parr have been seen about a mile downstream so hopefully salmon may now pass up the Dun beyond Lockerley Mill, where another fish pass has been installed, and beyond Holbury Mill. There are particularly good gravel beds just short of the blue pool, which is where the principal aquifer feeding the Dun, debouches, about ¾ mile upstream.

The scene around the fish pass still looks like the Somme battlefield but with Spring approaching the area is about to be resown. There remains one refurbished fish stew whose walls are now oak lined and we will be bringing on trout again when the adjacent ground can be accessed more easily. Do come and inspect the fish pass when its sides are no longer a mud bath. For the time being access is impracticable.
