Dear Mr Batsworth,

I am writing further to my acknowledgement of 9th July and your request
for information under the Freedom of Information Act. For your
information due to the nature of your request it has been handled in
accordance within the Environmental Information Regulations 2004.

You have requested the following information regarding the operation of
the Lea Bridge Sluices at the junction of the Lee Navigation and Old River
Lea, London E5-

`Any technical documentation, such as diagrams, maps, manuals and
operating instructions, describing the control systems, parameters and
functioning of the sluices. This should include details of the monitoring
of depth and flow of the Lea Navigation and Old River Lea, and how this
data and any other factors determine the operation of the sluices. Please
also supply copies of any communications or documents relating to any
modification in the operating parameters of the sluices as a consequence
of the construction of the Prescott Channel Water Control Structure and
associated river impounding.'

Following careful consideration, I regret to inform you that we have
decided not to disclose the detailed information that you have requested.

The information you requested is being withheld as it falls under the
exception in Regulation 12(5)(a) that its disclosure would adversely
affect international relations, defence, national security or public

I can though tell you in response to your request that the operation of
the River Lea sluices is unchanged following construction of the Three
Mills Lock and is in accordance with the land drainage consent issued by
the Environment Agency
