stickleback rescue

Off to French Tuesday evening through the park to discover that the same gigantic thunderstorm had caused a flash flood down in the Wash area, leaving two foot high banks of water weed in the woodland by the cascade. Stopped on the bridge to have a look and suddenly realised that there were dozens of sticklebacks on the ground all over the bridge where they'd been washed up by the flood and 2 huge goldfish that normally live in the pond by the road. I thought they were all dead then suddenly saw one flap and then another. Spent the next 10 minuntes searching and scooping up as many as I could that showed any sign of life and flinging them back. Must have got about 20 back in. The 2 goldfish were both injured but one was still breathing so I tossed that back too. I was amazed that so many were still alive - I suppose the dampness must have helped - but sad to think of all their nests that must have been destroyed.
Weds morning - the stream back to normal and plenty of sticklebacks in the water by the bridge, maybe they'll have another go. Trouble is now I'll feel obliged to go to the park and mount a fish rescue everytime there's a flood!
