Purpose

Fishlake is a village within Doncaster that
lies on the left bank of the River Don. During November 2019,
within the Fishlake area, 173 properties were recorded as having
flooded. Flooding has previously occurred during 2007.
During November 2019 a combination of two major rainfall events on
subsequent weeks produced a major flood on the River Don that first
exceeded the design standard of the left Riverside Bank and then
subsequently overtopped the secondary Barrier Bank. Significant
overtopping of the Riverside Bank occurred upstream and just
downstream of Stainforth Bridge (Fishlake Nab). The flood extent
was initially contained by the secondary level of defence, the
Barrier Bank, until this was overtopped, allowing the flood water
to quickly spread east, north and west across the village filling
up lower-lying areas and flooding many properties until most of the
village was submerged.Following the November 2019 flood event, the
highway had incurred damage and the drainage system needed to be
cleansed and the majority of the watercourses had to be de-silted
and regraded due to slippages, this cost was incurred by City of
Doncaster Council and the Internal Drainage Board. It is possible
that the findings of this report will identify a solution to limit
the financial impact of future flood events. A study has been
completed using £***** from Local Levy funding. The
information from the study will be used to inform the business case
to secure delivery the preferred solution/s identified. The purpose
of the additional funding, is to complete a detailed design and
construction of the preferred schemes. The preferred options
identified from the study are the installation of a penstock on
Sour Lane Drain in Fishlake and the construction of a pump pad for
temporary pumps adjacent to Taining Drain pumping station in
Fishlake.
