Hanningfield Reservoir is an artificial body of water located close to Chelmsford, and is owned by Essex and Suffolk Water. The reservoir was formed by flooding an area of South Hanningfield covering the ancient hamlet of Peasdown although contrary to popular belief, no buildings survive under the water, however, an earth removal machine was left 'in situ' and concreted over prior to filling. The reservoir was built in an area formerly known as Sandon Valley and large parts of the reservoir and surrounding countryside have been developed as a nature reserve. This part of the estate is leased by Essex Wildlife Trust and is home to vast numbers of wildlife. There are many footpaths in the woodland around the water where wildlife can be seen and hides have been erected to afford excellent views of the visiting and resident bird population. Members of the public are able to use the reservoir for seasonal fly fishing from both bank and from boats providing a fishing permit is bought in advance. The water is regularly stocked with rainbow trout, the heaviest fish ever caught to date weighing in at 24lb 1oz in 1998. There are two cafes at each end of the reservoir, the newest situated next to the fishing lodge being opened in 2007 with a deck overlooking the water, and the other located at the Essex Wildlife Trust visitors' centre. According to researchers, when full the reservoir can provide 1 bucket of water (each) for everyone in the world - This was devised from the fact that when completely full the reservoir will store the water for 200 continuous days (approx. 7 months.) although the reservoir currently only supplies water to the Southend, Thurrock, Dagenham, Barking and Redbridge areas.
