Stream flooding

This section of the track gets flooded after heavy rain.  It's because the culvert pipe under the track gets blocked with leaves and debris.  Then all the silt carried down by the stream piles up and we effectively hava a dam.
You can see in the picture above that nothing is coming through the pipe.  The water is just flowing over the track.

After a bit of poking with a long stick to release the blockage, the water gets through again and the flood level drops on the track.

 So if you are passing after heavy rain, and you see the water level rising . . . . . . . . . . . . . .
Culvert blocked with debris
Grab a long pole and try to poke it clear.  This would be really helpful.  I have left one pole by the willow tree on the left of picture 1-5 above, and another in front of the new tool store.
Unblocked again - but see the puddles on the track

It's quite satisfying when it gurgles and the water level goes down in a vortex like the water in your bath.
