Cringle Spillway Refurbishment
Manx Utilities will be undertaking a significant refurbishment of the spillway channel at Cringle Impounding Reservoir. This spillway, which has served the reservoir for the past 80 years, requires essential maintenance as identified in a statutory inspection, to ensure the safety and longevity of the reservoir and its dam. These works will enable this popular site to continue being a valuable amenity for the Island.
Key Points:
No Impact on Water Supply: Cringle Reservoir was retired as a raw water supply in 2008. Manx Utilities is required to maintain the reservoirs under the Water Act.
Proposed Works Include:
- Installation of a reinforced cast concrete structure lining the existing walls and bed of the spillway.
- Installation of a drainage system to collect and dispose of water from around and under the new structure.
- Clearing of the stilling basin downstream of the spillway.
Work Schedule:
22 April – 1 October 2025
The site, including the car park off Corlea Road, will remain open to the public. Occasionally, access to the dam crest may be restricted, but never for extended periods.
Information for Anglers:
The water level will be maintained around 1 metre below the top water level, as in previous year, as a safety measure.
Preliminary Works:
Manx Utilities is committed to protecting the species-rich grassland surrounding the Cringle Spillway. A landscape contractor will be on-site between 7 and 21 April to relocate species, particularly orchids and turf, away from the construction area to prevent damage. These works will not impact public use of the site, but visitors should be mindful of ongoing activities and supervise children and dogs.
