Dam a stream

A teenage boy and girl paddling in the river at Wasdale, Cumbria

Turn a stream into a pond, with your very own dam. Collect twigs, branches, stones and rocks to stop the flow of the water.

You can also make a dam on the beach, if there is water running into the sea. Godrevy beach in Cornwall is perfect for this. Can you plug one of the little streams that runs from the red river out to the sea? There’s plenty of seaweed and sand about for you to use.
Top tip: what goes up must come down – have fun smashing down the dam once you’ve made it, but don’t go in too deep.
