As our regular reader(s) will be aware, we have been closely following the water level in Crowdy Reservoir since the locked down spring of 2020. We also started following the water level of Colliford Lake very closely in the early summer of 2022 and during the subsequent drought. Cornwall is still subject to a “hosepipe ban“, officially termed a “temporary use ban”.
More recently we have been astonished to watch the graph of Colliford water storage on South West Water’s web site as the water level in by far the largest of Cornwall’s reservoirs failed to reach even 50% of total net capacity so far this year. By last weekend it had even started to fall:
This morning we went to see for ourselves what a half full reservoir looks like. Here is some of what we discovered, starting with evidence of previous human activity in the vicinity of what used to be Menniridden, recently uncovered for an extended period by the currently abnormally low water level in the reservoir:
Here’s the first in a series of videos we recorded. This one starts with Kasia wandering across the vast exposed “beach”, shot from on top of Colliford Dam:
As part of South West Water’s continued investment in water resilience across the region, the company is today applying for a permit to unlock supplies from a new source in Cornwall.
Hawks Tor was a redundant china clay pit on Bodmin Moor purchased by South West Water in March 2022, the brownfield site has been converted into a water source and should be supplying customers this month.
This will be the first reservoir brought online by any water company in the country during the ongoing drought, using the latest technology to secure supplies in the short term and provide greater longer term resilience.
Susan Davy, CEO of Pennon Group which owns South West Water, said: “We continue to deliver on our long-standing commitment to investing in our region’s water resources, building capacity where it is needed most and ensuring long-term water resilience across the region. Having only acquired the site a matter of months ago, Hawks Tor should be supplying customers in November. We Continue to take early and proactive actions to ensure the security of water supply for our region during the current drought and into the future.”
