For anglers and canoeists

A river in spate is no place for beginners. Weirs form strong towbacks, and trees in the water become strainers.

Many angling and canoe clubs check gauges like this one before heading out.

About the River Blackwater

River Blackwater, Essex

The River Blackwater is a river in Essex, England. It rises as the River Pant in the northwest of the county, just east of Saffron Walden, and flows in a generally southeast direction to Bocking, near Braintree, via Great Sampford and Great Bardfield. At Bocking, it becomes the River Blackwater, and veers east to flow past Bradwell Juxta Coggeshall and Coggeshall. It then veers south, flowing past Kelvedon and Witham, before reaching Maldon. There, it veers east again and empties into the Blackwater Estuary, which in turn meets the North Sea at Mersea Island. The river is connected to Domsey Brook in Essex.
