    Description: This is the Fish communities in rivers to be affected by Roadford Reservoir report produced by South West Water Authority in 1978. Surveys were carried, out on the Rivers Wolf, Thrushel, Lew and Lumburn, which are likely to be affected directly and indirectly by the construction and use of Roadford Reservoir. Of the upper reaches of three rivers to be affected directly by water releases, two were found to support abundant stocks of salmon and trout, and the third was found to contain abundant stocks of trout and eels. The River Thrushel will be affected indirectly and in this river salmon and trout stocks were present in slightly lower abundance than in others. Population estimates, densities, mean lengths and approximate biomass values were calculated. Other species were present in all rivers, usually in great abundance.

    Description: This is the River Bray fisheries survey 1978-80 report produced by South West Water Authority in 1981. This report aims to assess the possible effects of new abstraction conditions at Leahamford on the fish communities of the River Bray, surveys have been carried out in 1978, 197S and 1980. Field work was done in August and September each; year. Abstraction began in summer 1979. On the River Bray one site upstream and three downstream of Leahamford were chosen. One site on the River Mole was surveyed and is considered as a control site, being not directly affected by abstraction. The sketch map shows these sites in relation to Leahamford.

    Description: This is the Fisheries survey of the River Taw 1977 report produced by South West Water Authority in 1978. The upper reaches of the River Taw were severely polluted in October 1975 and there was widespread fish mortality. A survey was carried out to assess the recovery of salmonid stocks in the affected areas. Salmon showed a rapid recovery and trout have also recovered well. Both species have been assisted by widespread stocking. Several other species were present. Salmonid and total fish biomass was high. Further stocking of salmon is not recommended and it is also suggested that stocking with trout should be discontinued.

    Description: This is the Fisheries survey of the River Otter report produced by South West Water Authority in 1979. This report focuses on the trout fishery in the River Otter and the possible effects of abstraction and/or pollution. A survey was carried out to describe the fish stocks. Trout and eels were the dominant species. The population structure of trout was peculiar, there being relatively few juveniles. Growth was good and there were numerous trout of take able size in the river at the end of the fishing season. Variations in the parameters measured are explained and nothing can be attributed to abstraction or pollution.

    Description: This is the River Bovey (main Teign tributary) fisheries survey 1978 report produced by South West Water Authority in 1978. The aim of this report is to confirm or disprove the presence of alien coarse fish species thought present in the Bovey system. A chosen site was electro fished using D.C. methods wading upstream. All fish taken were measured and identified. Since it was not possible to distinguish between the young parr stages of migratory and non migratory trout, all parr taken have been included under the heading of Brown trout whereas in fact some of these parr may become migratory later in their life cycle.

    Description: This is the River Avon (including Glazebrook) fisheries survey 1978 report produced by South West Water Authority in 1978. This report aims to determine the penetration of Salmon into the River Avon system and to a lesser degree estimate the population of resident salmonids and other indigenous species. Six sections were electro fished at accessible points as detailed below. All fish were identified and measured. Each section was fished through three times to take the majority of the resident species. Small specimens of salmonid fry, eels and lamprey were common in almost all River Avon sections with the exception of Shipley bridge and Avon Dam but due to the mesh size of the standard dip nets used, many slipped through making accurate number estimation impossible.

    Description: This is the River Dart Fisheries Survey 1974 report produced by the South West Water Authority. The survey was carried out between July and October 1974 to assess the extent of the 0+ and 1+ Salmo salar L. population in the Dart catchment and thereby assess directly the success of the 1973/74 and 1972/73 spawning season. The survey showed that there were large numbers of salmon parr distributed throughout the upper reaches of the Dart, reflecting the successful spawning of the 1973/74 and 1972/73 season. It contains tables with survey sections locations, presence/absence for each section and location maps with spawning grounds and sampling stations.

    Description: This is the River Teign Fisheries Survey from August 1979 by the South West Water Authority.The River Teign was sampled by electrofishing at fifteen sites and population estimates, average lengths, weights and biomass were calculated for each species present, and where possible for individual age classes of those species. Results indicated that a stable community structure existed, and little had changed from 1963. Salmonids accounted for the majority of the biomass, and within this group trout were the most abundant in the headwater, and salmon in the lower reaches. All tributaries sampled had higher densities and biomass than the main river.The results were compared with other data collected from similar surveys of other rivers in Devon by the South West Water Authority. Both the average length of each age class, and the biomass in the main River Teign appeared to be lower than in most other rivers, although in the Rivers Wray and Lemon these values were particularly high.
