Denny Lake Pit 2
A section of the south bank adjacent the public footpath showed signs of iminent collapse. This lead to appraisal of the whole bank which resulted in a significant priority project to remove the overburden weight on the bank from overgrown gorse hedging and place full length planting along the base of the bank to help stabilise it.
As a result of the above appraisal attension was also given to the condition and stability of the northen bank. Gradual bank erosion is a natural occurance in lakes but due to the depth of water and steep incline of the sandy bank it is showing signes of sideways movement below the water line. Previously it had been considered that the tree/hedgeline along the bank was providing sufficient bank support however it is now clear that this is not the case as the sand in the bank is slipping and washing out between the roots.
Potentially there are several options which could help stabilise the bank and all will require significant work and cost. After lengthy consideration the committee decided to carry out a test section of bank stabilisation.
Works undertaken
Extensive hedge trimming to remove destabilising weight from banks
Costs significantly reduced thanks to the substantial works undertaken by the volunteer Saturday works teams, Expenditure limited to circa £500 for purchase of a seconhand transport boat and additional tools and another £500 for volunteer membership contributions.
Status - Delivered during April and May 2024
Provision of large scale planting to stabilise banks undertaken in two phases
Cost - £4680
Status - Delivered in June 2024
A test area part way along the north bank of Pit 2 has been created to test the effectiveness of replacing bankside trees/hedging with faggots and planting to help stabilise the bank.
Cost - £830
Status - Test area almost complete subject to limited top up of bank material to the rear of the faggots/planting and surface planting. - Awaiting appraisal of test area performance before undertaking similar works to the remaining sections along the same bank. An initial sum of £5000 has been allocated to the remaining works.
Provision of recessess opposite two swims to support the steep bund at the rear of the access path to enable anglers to sit away from thier rods and allow clear access past the rear of the adjoining platforms.
