In June and July 2007 there was extensive flooding of land in our Thoresby Bridge Pumping Station Catchment. The<br />
water level reached approximately +2.05m ODN at the Pumping Station. There was also flooding in North Cotes in<br />
2007 and 1979. There is a syphon under the Louth Canal connecting the east and west parts of the catchment to the<br />
PS.<br />
Prior to the installation of the Pumping Station at Thorsby Bridge in 1969 all water from the catchment flowed east<br />
down the old fleet to outfall approximately 100m u/s of the Louth canal outfall sluice. The old fleet was blocked off<br />
in North Cotes when the PS was built.<br />
The system has been modelled by Aecom using ISIS and the 100 year level at the PS is +1.87. However the model did<br />
not include any overtopping from the EA main rivers and I believe underestimated the flow from blow holes which<br />
are prevalent in the catchment. We have recently carried out a flood defence scheme <strong>for</strong> North Cotes – a flood<br />
defence bank to a 100 year design water level of +2.1m ODN. We have also raised all equipment at our Thoresby<br />
Bridge PS by 500mm to approximately +2.6m ODN .<br />

Dear Sir/Madam,<br />
Arup are currently involved in a Flood Risk Assessment on behalf of <strong>Partnerships</strong> <strong>for</strong> Renewables at a site adjacent to<br />
Louth Canal, Thoresby Dike and Old Fleet Drain at approximate grid reference E532974, N400135 (please see<br />
attached plans).<br />
It is believed that this area falls under the jurisdiction of the Lindsey Marsh Internal Drainage Board with regards to<br />
the management of local water levels and land drainage. The Flood Risk Assessment of the site is based upon readily<br />
available in<strong>for</strong>mation, and so we are hoping to collate any in<strong>for</strong>mation and/or local knowledge that may be shared<br />
relating to the local drainage system and known flooding issues at and around the site.<br />
Accordingly, any of the following in<strong>for</strong>mation that you may be able to provide to assist the FRA of this would be<br />
much appreciated:<br />
? any known local flooding issues and /or any flood mechanisms associated with the local drainage system<br />
? any photographs, accounts or anecdotal in<strong>for</strong>mation concerning historical flooding at or near the site<br />
? any extreme event water level data that may be available <strong>for</strong> the local drainage system<br />
? any in<strong>for</strong>mation concerning existing high flow maintenance regimes / responsibilities / flood management<br />
measures <strong>for</strong> the local drain networks<br />
? any specific requirements <strong>for</strong> this site relating to management of flood levels and surface water drainage<br />
I would be grateful <strong>for</strong> any in<strong>for</strong>mation that you may be able to provide us, or if you may be able to provide a relevant<br />
contact with whom it may be possible to discuss these issues with further.<br />
Please do not hesitate to contact me concerning the above request. Many thanks in advance <strong>for</strong> your time and I look<br />
<strong>for</strong>ward to hearing back from you,<br />
Kind Regards,<br />
Sarah<br />
