Title: Impact of sediment regime on salmonids
Author: P.A. Carling
Document Type: Monograph
Abstract:
Sedimentation in the River Wolf and other tributaries of the Tamar, affected by construction of Roadford dam and operation of the future Roadford reservoir, is of importance to salmonid fish. Similarly salmonids in rivers receiving future transfers of Roadford water to the Torridge catchment will be affected by new sediment regimes. Data which have been collected on suspended and bed sediments in these rivers need interpretation, in terms of their effect on salmonid migration and breeding success. The objectives of the work reported here are: a) To evaluate data obtained in the January and September 1987 surveys of river gravels downstream of Roadford Reservoir, in terms of the needs of spawning salmonids. b) To recommend future sediment survey strategies to be used in the Tamar and Torridge catchments, to assess the impact of sediment regimes on salmonid fisheries, having regard to the construction and operation of Roadford Reservoir.
