The Irwell. Story of an industrial river

This is the Irwell: Story of an industrial river document produced by the North West Water in 1979. This report is a leaflet format document. It focuses on the historical evolution of River Irwell, since it was “born” the river Irwell, about three hundred million years ago when shallow seas covered most of south east Lancashire and Europe to present years. It looks at Irwell’s pollution, highlighting the Irwell’s lower stretches were some of the region was the most polluted due to the population growth and establishment of industrial activities i.e. Lancashire’s great cotton industry, breach and dye works, paper mills, tanneries, chemical and gas works. Wastes from these industries were discharged directly to the river, together with crude sewage from an ever increasing population. However over the years the condition of the Irwell was gradually improved.

Effects of water quality in Bassenthwaite Lake on anglers' catches of salmon and sea-trout in the River Derwent

This is the report on the Effects of Water Quality in the Bassenthwaite Lake on Anglers Catches of Salmon and Sea-trout in the River Derwent April 1993 by the Institute of Freshwater Ecology. An analysis of the catch statistics for salmon and sea-trout in the Rivers Derwent and Cocker was undertaken in relation to available information on the algal water quality in Bassenthwaite Lake to test the hypothesis that poor catch returns were associated with a deterioration of water quality within the lake. Analysis of the catch statistics failed to reveal any correlation between water quality and catch returns for either species of fish and it is concluded that any water deterioration in Bassenthwaite Lake has not caused any major damage to the salmon and sea trout fisheries of the Derwent/Cocker system. This conclusion is supported by the analysis of the Windermere/Leven and Crake system, where no correlation could be found between lake water quality and downstream catches of migratory salmonid fish. However, the possibility still exists and such an effect might be detected by further field work on the macroinvertebrates and on the composition of potential salmonid spawning in the area.

River habitat survey and geomorphological evaluation of the Glaze Brook Catchment

This is the River habitat survey and geomorphological evaluation of the Glaze Brook Catchment report produced by the Environmental Research and Consultancy of the University of Liverpool in 2002. The major aims of the project were to provide baseline information on river habitats in the Glaze catchment using standard River Habitat Survey (RHS) methods (sampling 25% of the catchment length) and, through the geomorphological audit, to assess the distribution and intensity of geomorphological processes, notably sediment transfer, sources and sinks. This information was then used to develop informed management recommendations. The Glaze catchment is a heavily modified watercourse of generally poor habitat quality. The most important factors contributing to the low quality of the sites are poor bank and channel features; low diversity/absence of channel vegetation; paucity of bankside trees and, to a lesser extent, a lack of channel substrate diversity. The high degree of modification relates principally to extensively resectioned banks and channels plus extensive culverting in the urban parts of the catchment.

River Gowy rapid corridor survey July 1995. Ecology South Mersey

This is the River Gowy rapid corridor survey July 1995: Ecology South Mersey report produced by the National Rivers Authority North West Region in 1995. This report looks at the survey carried out by the South Mersey Ecology Team prior to routine deweeding operations on the main River Gowy at the end of July, 1995. The survey covered Flood Defence Stretch References RGOW03 to RGOW16. These stretches were further divided into a series of 43 stretches, each one being approximately 500m in length for ease o f mapping by Ecology. Recommendations for each length have been cross-referenced with the Bill of Quantities where possible, e.g. retention o f margins. In Flood Defence stretch RGOW03, the South West Winter Wetland forms an important habitat for birds. In stretches RGOW04 to RGOW05, the Gowy Meadows and Ditches have been designated a Grade A, Site of Biological Importance, by Cheshire County Council due to the nature of the acidic grassland and diverse ditches. In stretches RGOWIO to RGOW11 the left bank forms Hockenhull Platts, Grade A Site of Biological Importance and County Trust Reserve. In stretches RGOW15 to RGOW16, the area from Mill Farm to the Shropshire Union Canal is a Grade A Site of Biological Importance. These sites are very sensitive and detailed recommendations for working practices can be found in the relevant sections o f the survey.

River Gowy and Thornton Brook improvements. Environmental Action Plan March 2000

This is the River Gowy and Thornton Brook improvements: Environmental Action Plan report produced by the Environment Agency in 2000. This Environmental Action Plan relates to the proposals by the Environment Agency to improve the flood defences of land adjacent to the River Gowy, about 3 km east of Ellesmere Port, Cheshire. The purpose of the Environmental Action Plan (EAP) is to provide details of how the issues addressed in the Environmental Statement (ES) will be carried through to the completion of the project. The EAP represents a commitment to the environmental recommendations formulated during the environmental assessment process and should be closely adhered to during the design, construction and post project monitoring o f the works. For any matters that cannot be finalised until during construction the constraints will be detailed in the plan so they are implemented in the contracts.
