The River Rother, once one of the most polluted rivers in Europe, runs through Catcliffe and is one of the hidden gems of the village. There are walks which take you along it's banks and the section under the stewardship of The Brinsworth, Catcliffe and Treeton Angling Alliance (CBTAA) provides some great fishing, with platforms out over the water at regular intervals. Day and Season Tickets are available and are well worth the few pounds cost when you can catch specimens in excess of 10 lbs on a regular basis.
The CBTAA is responsible for all things to do with fishing and operate outside the remit of the parish council. Interested parties should contact them direct.
In August 2016, the Wildlife Trust upgraded the river facilities to improve matters for wildlife and the local environment.
On the eastern bank of the river lies Catcliffe Flash which was created by overspill from the river and submergence caused by mining. This is a haven for water based wild life. The whole area around the river has been designated a Local Nature Reserve (LNR) and is managed by the Wildlife Trust.
