Reallocation of compensation release to restore river flows and improve instream habitat availability in the Upper Derwent catchment, Derbyshire, UKMaddock, I. P. ...The Upper Derwent catchment is situated in the Peak District National Park in North Derbyshire, England and includes the Derwent Valley Reservoir System. The natural inflows to the reservoir system ... are boosted by flow diversion schemes from the River Ashop and River Noe, leaving almost dry stretches in these rivers for long periods of time. Compensation releases are made into Jaggers Clough and the River Derwent. This study examined the possibility of altering the operation of the diversion scheme and compensation flow releases,both temporally and spatially to restore flows within these dry reaches. The overall intention was to minimize the ecological impacts of regulation in the four rivers whilst protecting the yield of this critical public water supply. The study utilized the Physical Habitat Simulation System(PHABSIM) to identify and compare feasible operational changes. This technique enables quantitative comparisons of the suitable habitat available under different flow regime scenarios. Brown Trout is the most abundant fish species in the Upper Derwent streams, with Grayling, Brook Lamprey and Bullhead also present. The invertebrate fauna is typical of upland streams with neutral to acid waters. The ecological data were assessed to identify suitable target species/life stages for use with PHABSIM. Brown Trout, Grayling and four invertebrate families (Rhyacophilidae, Leuctridae, Chloroperlidae and Heptageniidae) were selected.
