Moorhen - Cromford Canal

In recent weeks I've walked the Cromford Canal, not in one go but in three sections. I was mainly searching for Water Vole but without any success. 
It is worrying that, at least from my records, the Water Vole has disappeared, or if not disappeared certainly declined in number at many of its local strongholds.
At least the Moorhens appear to be doing well and I counted at least 10 pairs of Little Grebe along the canal. 
Surprisingly, I've never posted Moorhen on the blog so that's now rectified.
