Lake Restoration Southampton

Kingcombe were recently commissioned to restore a lake for a private client in Southampton. The lake and the surrounding area had been neglected for the last 30 years, becoming highly vegetated and accumulating a large amount of silt build-up. Working with the client, Kingcombe designed a scheme to stabilise the surrounding banks and island, while restoring the lake back to its natural beauty. The project involved removing overgrown vegetation and desilting the main body of the lake. Once the silt was removed, a 2m high x 24 m long gabion wall was constructed to stabilise the bank as a summer house is planned to be built next year. A Timber post crescent was erected to provide a sunken seating area overlooking the estate. The island was also found in disrepair, with overgrown vegetation and requiring stabilisation. Existing trees and shrubs were removed, allowing the island and the adjacent bank to be re-established with close-butted timber posts. Once desilting and stabilising works were complete, a new stone outlet structure was constructed with timber stop logs set in galvanised steel frames, allowing the client to adjust the lake level accordingly. A stone-faced slipway was constructed to allow access underneath one of the bridges and new stone weir to enhance the inlet area. To complete the restoration project, two bespoke handcrafted bridges and jetty’s were installed for easier access to the island, linked by a new curvy stone path. Once the lake has been refilled, our team will return to the site and install the aquatic planting.

Desilting and Lake Restoration

Regular maintenance to a lake is vital to preserve its natural beauty, otherwise, the lake will quickly end up in a poor condition. Kingcombe Stonbury have extensive experience in the restoration of historical lakes and a good example of this can be seen throughout a recent lake desilting and restoration project that was undertaken for a private client in Oxfordshire. The formal Water Gardens on the Estate were originally built by John Harborne in 1615 and further cleared and restored by the then proprietor Sir Harald Peake in the 1960’s. Since then, the main spring fed lake had fallen into disrepair, accumulating a large amount of silt and becoming significantly overgrown, blocking light and wind and causing the water to become stagnant. The land owner entrusted Kingcombe Stonbury with the contract to restore this historic lake back to its former 16th century glory. Working closely with Natural England, the project involved the removal of several thousand cubic metres of silt from the main body of the lake, cutting back perimeter vegetation and installation of a new drain down penstock.  A fleet of dumpers transported and spread the removed silt onto adjoining farmland, in accordance with our permit for mobile plant for land spreading. The silt was also used for re-profiling and landscaping the lake perimeter and margins. On completion of the desilting works, the existing penstock was replaced with timber stop logs set in steel frames and fixed to the existing structures. Reconstruction works were also carried out on the overflow channel, in keeping with the cobbled design of the original structure. Control of over-shading marginal vegetation and the removal of excessive silt accumulation has enabled the re-growth of oxygenating aquatic plants and helped restore the ecological balance of this historic lake.   The client and Natural England were delighted with the restoration of this historic landscape feature.
