East Anglia Mountain Rescue Team

This is a "drain" not a river. It was built to drain water away from the fens. Which as you can see is very flat. We have our own Mountain rescue team here. But it's a joke, our mountain rescue team raises money for Charity because there aren't any mountains to rescue people from. There aren't even any hills. It's just mile upon mile of flat. The land is not much above sea level so the water is drained into a tidal river with the aid of locks that stop salt water getting back onto the land at high tide.
