March was mild overall with changeable conditions, alternating between unsettled spells and drier interludes in early and mid-month. As a whole, UK rainfall was average with a strong regional contrast marking a return to the usual rainfall gradient of the UK: northwest Britain recorded above average totals while eastern Scotland and central southern England saw below average rainfall. River flows were in the normal range to above in northwestern areas with some groundwater-dominated catchments in central southern England remaining notably high. Elsewhere, flows were generally in the normal range, with some rivers above normal in south Wales and southwest England. Groundwater levels generally decreased or remained stable during March, reflecting relatively drier conditions, but high to exceptionally high levels dominate across England. Soils remained wet in northwestern areas but began to dry across central and southern England. Reservoir stocks were stable and above average at the national scale, although a few impoundments showed residual deficits (e.g. levels rose at Grafham but remained 7% below average). The UK Hydrological Outlook indicates normal to above normal flows in western Scotland and southern England over the next three months, combined with the passage of storm ‘Dave’ in early April, the risk of localised flooding is elevated. With above average reservoir stocks due to a notably wet winter half-year, the water resources situation is healthy entering the summer half-year.
