Monthly water situation report Midlands Region Summary – December 2015 Rainfall – Most Midlands hydrological areas received ‘notably high/above normal’ amounts of rainfall. Soil Moisture Deficit – Normal soil moisture deficit for December. Soils are saturated across much of the Midlands. Deficits are limited to eastern parts of the region. River Flows – River flows across the Midland are ‘normal’ or greater than normal. Groundwater Levels – Most groundwater monitoring sites were ‘normal’ with the exception of Hodhill and Four Crosses (‘below normal’) and Ram Hall (‘notably high’). Reservoir Storage – At the end of December all reservoir levels were above average storage, with the exception of Charnwood (59.6%), Dove (66.5%). Carsington is also near its average storage. Our former Midlands region is split into three areas: Midlands West is now Shropshire, Herefordshire, Worcestershire and Gloucestershire (SHWG) Area, Midlands Central is now Staffordshire, Warwickshire and West Midlands (SWWM) Area and Midlands East is now Derbyshire, Nottinghamshire and Leicestershire (DNL) Area. Rainfall In December rainfall totals ranged from 112% to 209% of long term average. The greatest rainfall totals were over western parts of the region (Welsh Mountains (298mm), Middle/lower Severn main channel (115.3- 126.1mm), Wye (164.9mm)) and on the high ground of the Derwent (139.7mm). Relative to long term average (LTA) most hydrological areas received greater than average rainfall. The only exceptions were the Dove (100.1mm) and Soar (72.6mm) catchments which had ‘normal’ amounts of rain. ‘Notably high’ rainfall amounts fell in southern parts of the Midlands (Wye (164.9mm), Lower Severn (115.3mm) and Avon (93.2mm)). ‘Exceptional high’ rainfall amounts occurred in the Welsh mountains (298.7mm) with twice the LTA. Rainfalls over the last 3 and 6 months periods were ‘normal’ or greater than normal across the Midlands. The wettest areas occurring over the Welsh mountains, Lower Severn, Avon, Wye and Derwent. Please refer to Midlands Rainfall Map and Midlands Rainfall Charts Soil Moisture Deficit Soil moisture deficit across the Midlands is currently minimal. This saturation of soil is typical of December. Only the eastern parts of the region are shown to be non-saturated, the maximum deficit (11-40mm) occurring in the Trent lowlands. Please refer to the SMD Map and the Midlands SMD Charts River Flows Most of the River Severn catchment had flows which were ‘above normal’ or greater. Exceptional flows occurred on the Tanat at Llanyblodwel, Severn at Bewdley and also on the Wye at Redbrook. The Trent catchment had mostly ‘normal flows’ with the exception of ‘above normal’ flows on the Derwent at Derby St Mary’s.

Water abstraction licence restrictions as of 07-01-2016. Please note: The No. of thresholds crossed does not refer to the individual numbers of abstraction licences restricted. It instead relates to the number of Hands off flow thresholds that are currently in force at time of print (i.e. Primary, Secondary etc.). River Severn Operations (as of 08-10-2015) The River Severn is regulated to maintain a minimum flow at Bewdley gauging station. This ensures sufficient water flows along the river to support environmental and water supply requirements. Flows at Bewdley are monitored between April and mid-October and regulation instigated when flows drop below a specific threshold at Bewdley. The end of the regulation season was confirmed on 17th November 2015 following 63 days of regulation. River Wye Operations (as of 08-10-2015) Flows in the River Wye at Redbrook were below the regulation threshold at the beginning of November and so regulation releases were made from the Elan reservoir up until 1 November 2015. The River Wye Regulation ceased on 2 November 2015 as the river returned above the 1209 Ml/d threshold under the winter operating conditions. Groundwater Levels Most groundwater monitoring sites were ‘normal’, with the exception of ‘Below normal’ levels at Hodhill (Magnesian Limestone), Four crosses (Sherwood Sandstone) and ‘notably high’ level at Ram Hall. During December winter recharge occurred at Anthony’s Cross, Hodhill Farm, Ram Hall, Rider Point and more minor increases in level at Four Crosses and Heathlanes. Please refer to Midlands Groundwater Map and Midlands Groundwater Charts Reservoir Storage At the end of December all reservoirs levels were above average storage, with the exception of Charnwood (59.6%) and Dove (66.5%). Carsington & Ogston (76%) is also near (<1%) its average storage. Clywedog, Vyrnwy, Derwent system, Tittesworth and Elan are at/or near 100% full. All other reservoirs increased in storage during December except Carsington & Ogston which had little change.
