Our open days are on the second Saturday and second Tuesday of each month from April until October. We will also open on the early may bank holiday.

The pump will be run on the Saturday open days. On Tuesdays the pumphouse will be open but the pump may not be running.

Running of the pump is subject to river conditions, ageing machinery, and ageing volunteers!
