Environmental effects of drought and abstractions of River Ouse fisheries, summer 1997

This survey was the second year of a three year study to examine fish populations in relation to low flows, drought and abstraction in the River Ouse. To fully evaluate the possible effects on fisheries the study set out to encompass fish population surveys from fry to adult stock, analysis of angler catch data, reports from anglers and river reports from Environment Agency Fisheries staff.
