The HS2 Railway (phase 1) which is due to be complete in 2026 will cross the Colne Valley
on a viaduct dissecting Harefield No2. The Harrow Angling Society has actively campaigned
against the viaduct in favour of a tunnel. Unfortunately despite a coordinated campaign the
tunnel option was turned down. The Society has therefore been talking to HS2 Ltd to obtain
agreements on access to their Harefield No1 and No2 lakes, both during and after
construction of the viaduct.
In November 2016 the Society petitioned the House of Lords Select Committee and obtained
the following assurances:-
- HS2 Ltd will allow, were reasonably practicable, pedestrian and vehicular access to
No1 and No2 Lakes during construction of the Colne Valley Viaduct.
- HS2 Ltd will require the nominated undertaker to work with the Harrow Angling
Society, as far as is reasonably practicable, on the details of the appropriate
ecological mitigation plan for the reed beds within the Harefield No 2 lake.
The Society was also very concerned about the potential for pollution in and around No 2
during construction of the viaduct. HS2 Ltd have said the code of construction practice
covers all the necessary safety measures required to be put in place by the contractors
during construction to ensure the potential for pollution is kept to a minimum. The
Environmental Agency (EA) will also be responsible for conducting regular water quality
checks during construction to ensure water quality is maintained.
The construction of the viaduct will take approximately four years to complete. HS2 Ltd has
said construction is not likely to start before April 2019. During the construction of the HS2
viaduct No2 Lake will subject to significant building activity, however the Harrow Angling
Society Committee will work with HS2 Ltd to ensure Fish welfare and angling access is
maintained during this period.
