The Environment Agency says people shouldn't be "alarmed" by the changing water levels along the River Derwent in Belper, because they have been altered deliberately.
The levels are being dropped to remove a tree which is blocking the sluice gates. The agency says the river could end up looking like these scenes from a similar incident in 2015.
