The River Parrett flows through the counties of Dorset and Somerset in South West England, from its source in the Thorney Mills springs in the hills around Chedington in Dorset. Flowing northwest through Somerset and the Somerset Levels to its mouth at Burnham-on-Sea, into the Bridgwater Bay nature reserve on the Bristol Channel, the Parrett and its tributaries drain an area of – about 50 per cent of Somerset's land area, with a population of 300,000. The Parrett's main tributaries include the Rivers Tone, Isle, and Yeo, and the River Cary via the King's Sedgemoor Drain. The long river is tidal for up to Oath. The fall of the river between Langport and Bridgwater is only, so it is prone to frequent flooding in winter and during high tides. Many approaches have been tried since at least the medieval period to reduce the incidence and effect of floods and to drain the surrounding fields. In Anglo-Saxon times the r
El río Parrett fluye a través de los condados de Dorset y Somerset en el suroeste de Inglaterra, desde su fuente en las fuentes de Thorney Mills en las colinas alrededor de Chedington en Dorset. Fluyendo al noroeste a través de Somerset y los niveles de Somerset a su boca en Burnham-on-Sea, en la reserva natural de Bridgwater Bay en el canal de Bristol, el Parrett y sus afluentes drenan una área de – alrededor del 50 por ciento de la superficie terrestre de Somerset, con una población de 300.000. Los principales afluentes del Parrett incluyen los ríos Tone, Isle, y Yeo, y el río Cary a través del río King's Sedgemoor Drain largo. El río es tormentoso hasta Oath. La caída del río entre Langport y Bridgwater es sólo, por lo que es propenso a inundaciones frecuentes en inviernos y tormentas altas.
