Reservoirs: Maps

Volume 493: debated on Monday 1 June 2009

To ask the Secretary of State for Environment, Food and Rural Affairs (1) what recent progress has been made in mapping large reservoirs; (277651)

(2) how many reservoirs have been mapped since December 2008;

(3) what progress the Environment Agency has made towards the objective of providing inundation maps to local resilience forums by the end of 2009.

Between May 2008 and February 2009 the Environment Agency undertook trial and pilot studies on 49 reservoirs. Based on the results of these, it is undertaking two phases of work:

Phase 1 (March to September 2009): low resolution assessment of downstream risk to life for all reservoirs covered by the Reservoirs Act 1975 (i.e. those over 25,000 cubic metres capacity). As at the end of May, 57 reservoirs had been mapped under this Phase.

Phase 2 (June 2009 to January 2010): higher resolution assessment on the higher risk reservoirs identified in Phase 1.

The handover process to Local Resilience Forums is still to be finalised.
