Earlswood Lakes - major repairs

From April 2021 we're carrying out some major repairs to Earlswood Lakes. As this is likely to have some impact on residents and visitors we wanted to share our plans and explain why this work is important.

Earlswood Lakes Works Update 28 October 2021

We are close to completing our £1.6 million programme of improvements to the reservoirs at Earlswood. The works, which are required to ensure the reservoirs are compliant with reservoir legislation, have included strengthening the core of the main dam along Valley Road to improve its resilience during flood events.

  • A new culvert and headwall have been installed at the bottom of Mason Lane, between Terry’s Pool and the Canal Feeder Channel.
  • The Canal Feeder Channel has been dredged, and coir roll soft bank protection has been installed and planted with native plant species. Concrete bag erosion protection has been added to the pathway alongside the feeder channel, and the pathway has been widened and resurfaced.
  • New angling platforms have been installed in Engine Pool, next to the pathway alongside the Canal Feeder Channel and next to the footpath on the Malthouse Lane side of Engine Pool.
  • New rock armour protection has been installed along the main dam face and in the River Blythe.
  • In Engine Pool voids have been filled with concrete bags for erosion protection.
  • Trenches have been dug along the dam embankment and new drainage installed. The grass embankment has been re-seeded and re-enforcement mesh added.
  • To strengthen the main dam, a new concrete wall has been installed in the dam beneath the Crest Road, alongside Valley Road.
  • Using soil from the main dam works, the footpath along the top of the River Blythe embankment, alongside Windmill Pool, has been raised. Work continues to re-profile and resurface the pathway, making it accessible all year round. This footpath is due to reopen by mid-November.
  • The waste wood generated by the work here has been secured in Windmill Pool to provide habitat for invertebrates and fish within the water, and a step up over the metal piles for wildlife.
  • With the stone used to create a temporary access track across Engine Pool, we’ve created a new island ridge for water birds to safely perch on.
  • The main Valley Road reopened on 20 August and the Malthouse Lane Causeway Road and Crest Road above the dam (alongside Valley Road) reopened 15 October.
  • The lakes are now refilling with rainwater, allowing sailing to resume, and the temporary works compound in Malthouse Lane Car Park is being dismantled.
  • Wood Lane car park will remain closed until mid-November, when the Trust’s final inspections are complete.
  • The Trust is looking at ways to fund further footpath improvements at the lakes in the future.
