For the purposes of this FRA, “The Site” is defined as the 3.5km linear connecting
route, including all temporary access roads and compounds associated with the
working area. The proposed new overhead line will comprise 9 new pylons, including
one replacement pylon on an existing overhead line.
The site is located approximately 3km south of King’s Lynn town centre. The Puny drain
is located beyond the eastern site boundary of the site with the village of West Winch
located further to the east. The Great Ouse Relief/Cut Off Channel is located to the
west of the site with the Great Ouse River located further west.
The surrounding area is predominantly flat with much of the land comprising large-scale
arable farmland. Built development in the area surrounding the site generally comprises
small villages, individual properties and farms. With the exception of King’s Lynn, the
most significant area of development is West Winch.

5.2 Hydrology
5.2.1 Area Hydrology
The site area and surrounding area is characterised by low-lying farmland, which is
drained by a series of controlled waterways. The majority of the watercourses and
drains in the area are managed and maintained by the East of Ouse, Polver & Nar
Internal Drainage Board (IDB) and flow in a south to north direction. The drainage
network eventually discharge into The Wash via the Great Ouse River, which lies
approximately 7km to the north of King’s Lynn and is a nature conservation site of
international importance.

The principal watercourse is River Nar, which flows south to north, with the site area
crossing the Nar twice.
The site and the area immediately surrounding the site is crossed by several smaller
drainage ditches, with named drains such as The Puny Drain (fluvial) located
approximately 500m to the east of the site, the North Sea Bank drain flows adjacent to
the High Road to the north of the site and the Thiefgate drain is located between the
River Nar and the Thiefgate Lane to the south of the site. These drainage features are
all managed and maintained by the IDB.
The Great Ouse Relief Channel is located approximately 500m to the west of the site
with the River Great Ouse (tidal), 1km -1.5km further west.
The River Nar, The Great Ouse Relief Channel and the River Great Ouse are all
classified as Main Rivers.
