As reported in our February magazine, South Gloucestershire Council has agreed to allocate £250,000 from its Highways Maintenance programme to fund enhancement works to the Three Brooks Lake in Bradley Stoke.

Streams flowing from Patchway, Hortham, Little Stoke and Stoke Gifford all feed into the lake, which was constructed in 1993 to create an amenity pond for local residents. The lake was last desilted in 2005 and is now in need of desilting again.

During the summer of 2019, low water flow exposed large areas of silt, exposing wildfowl nesting on the islands to predators including foxes and cats. This winter the high rainfall experienced across the country has led to the lake flooding twice.

The timing of the desilting works is restricted to being carried out between November and February due to the protected wildlife which uses the wetland area, including water voles and otters. Between now and next autumn, the council will appoint a contractor and work with the Environment Agency to obtain a bespoke licence.

The plan will be to reduce the water level in the lake by opening up the penstock (sluice gate). At the same time, a professional fishery will catch all the fish, store them safely and then release the fish after the works have been completed. The lake will then be desilted by machine and the silt moved using dumper trucks to a spoil area (see map) which has recently been cleared in preparation for the main scheme starting in the autumn.

As part of this project and following requests, a 300-metre stretch of pathway along the northern edge of the lake will be surfaced, linking the northern end of Juniper Way with the reserve and making the lake more accessible to visitors.

With the Three Brooks Local Nature Reserve becoming increasingly popular, the council says public safety will be a high priority. Updates will be provided in the form of on-site notices and through posts on the StreetCare Facebook page www.facebook.com/sglosstreetcare
