This Drainage Board was formed in 1962 for two former Districts to create greater efficiency. The Board is a Statutory Body Authority governed by the Land District Act 1991.
The District is located on a peninsula of former marshland situated at the confluence of the River Ouse, River Aire and River Don (Dutch River). The area is very low lying below the mean water mark.
The protection for the Rivers is affected by flood banks maintained by the Environment Agency and are capable of withstanding a 1 in 200 year storm.
