Abstract:
Otters have been increasing in numbers and distribution across Devon, however their movement into East Devon has been slow. One of the reasons for this is thought to be a lack of suitable sites for otter holts. In general, the otter population of the River Otter and its tributaries is promising and a further sign of the improving health of the catchment. The Wimbleball Pumped Storage Scheme was instigated by South West Water Services Ltd to augment the natural flow of water to Wimbleball Reservoir. Wimbleball Reservoir is used by both South West Water and Wessex Water, providing supplies for Wimbleball Supply Zone which includes the Sid an Otter catchment. Water is abstracted from the River Exe at Exebridge and pumped via an underground pipeline to Wimbleball where it discharges to the reservoir. The pumping operation is permitted to take place during the period November to March. It was first used between 4 February and 20 March 1997, pumping 384,886 cubic metres of water to the reservoir. This new issue combines actions previously included under the issues of siltation of spawning gravels and changes to bankside flora. It also includes new actions. Erosion is a natural process. Rivers and coastlines change as the forces of water shape the land. However, there is growing concern over the rapid erosion which is occurring in certain catchments. The Sid and Otter catchment is particularly vulnerable as its' soils are very easily eroded. In addition the increase of some agricultural practices in the catchment, such as outdoor pig farming and the growing of maize has greatly increased soil erosion in certain parts of the catchment.
