With the ongoing repair works at Toddbrook Reservoir meaning this key source of water for the canals isn't available, together with works to reinstate the feeder channel at Combs Reservoir, the summer boating season on this part of the canal network started with a much-reduced supply of water than normal.
The water in Bosley and Sutton reservoirs, other water sources for the two canals, has been used sparingly and has successfully prolonged the water supply to maintain navigation into mid-July. This has included implementing restricted opening times at lock flights since April.
However, continued hot, dry weather means that reservoir holdings are now very low even taking the recent rainfall into account, and so a navigation closure, which will reduce the call of water that the canals need, will be put in place along the Marple and Bosley lock flights. The remaining reservoir holdings are required to supply a continued reduced feed to keep the canal topped up to protect the canal infrastructure, keep boats afloat, and meet our responsibilities to protect the ecology along the waterways.
We're working to reinstate a feed of water from Combs Reservoir, with ongoing works to the feeder channel. Trials are due to commence on Monday 26 June to convey water along the feeder channel. If these are unsuccessful, we plan to reinstate a supply of water from the reservoir by pumping it into the River Goyt and then back into the canal network at Whaley Bridge. If a feed from Combs can be reinstated, then the planned closure of the lock flights will come into effect on Monday 10 July, however, if Combs cannot be brought back into use, the closure could take effect sooner. We will be confirming details with boaters and local businesses as soon as we possibly can.
Whilst the closures will prevent the use of the lock flights, it will still be possible for boats to cruise between them. The towpath will remain open as normal. Water holdings will be monitored carefully throughout the summer and if there is adequate rainfall it will be possible to reopen the canals to full navigation.
During the planned closure of the lock flights, we're looking into bringing forward essential maintenance along the Marple Flight, which had originally been scheduled for this winter. To conserve as much water as possible whilst these closures are in place, both lock flights will be padlocked closed and the gates sealed with ash to reduce leakage.
We understand what an impact this has on boaters and boating businesses and apologises for the inconvenience and uncertainty that the closure brings.
