Engineers have bypassed a dam at the head of the Grand Canyon to release hundreds of thousands of tons of sediment into the Colorado river. The move was made in a bid to restore the sandbanks, which have been eroded but not replenished since the Glen Canyon dam was built. Sandbanks are vital to stabilise declining fish and plant populations. The £2M project involves four giant steel pipes passing 1,160m 3/s of water.
