The Wraysbury River floods at Staines Moor

A quick visit to the patch this morning found a fair amount of flooding on Staines Moor after the recent heavy rains, and the Wraysbury River having burst it's banks and flooded much of the south-west corner. The water level of the Colne is also very high, but the artificial raised banks created from material dredging from the river bed in the last century have so far preventing the river from flooding.

4 Little Egret, 4+ Common Snipe, 49 Meadow Pipit and 100+ Black-headed Gull were on the floods and along the Colne, 80+ Fieldfare were still present in the NW corner along with 32 Redwing, 8 Linnet, 8 Skylark, 22+ Starling, 1 Reed Bunting. Some movement noted overhead: 85 Woodpigeon SSW in small groups, 5 Gadwall SE, 1 Common Buzzard W, 9 Pied Wagtail (mainly NW). Also noted were 2 Grey Wagtail, 1m Stonechat, 3 Little Grebe on the Colne and a distant possible Woodcock at dawn in the NW corner.

Found a Mottled Umber Erannis defoliaria floating on one of the pools. It was still alive so I rescued it by placing it in a tree, then slapped it on the Moor's moth list!

The artificial raised banks of the Colne at Staines Moor, created from material dredged from the river bed, usually prevents the river
from flooding nowadays - a major reason why the Moor no longer supports large numbers of wintering waders and wildfowl.

Pools on Staines Moor viewed from The Butts. With the banks of the Colne raised, the pools on Staines Moor form only after heavy
rain and are only able to persist with a high water table.

  1. The Staines Moor is still on my wishlist to visit one day. Your blogs only make that wish stronger. Thanks for sharing. What is the best way to get to the Moor, I wonder, Lee. But I will wait until the heavy storms have cleared.

  2. I too love STAINES MOOR and have bee there many times. I took some time and made some videos of it becasus it is so unique just nestling there between the M25 and Heathrow T5.
