Report on Water Resource Development in East Devon
Abstract:
Studies have already been made of the relation between fish catches and river flow in the R. Axe and these provide essential information relevant to the present study, particularly in describing in detail the data-base, the statistical methods of analysis, the results obtained, and the caveats to be borne in mind in drawing conclusions.
The present report deals with a further analysis of daily catches of salmon and sea trout in relation to daily flows, as required by Dr. J. E. Cochrane of the National Rivers Authority, South West Region (NRA), in order to confirm the existence of a relationship between fish movement and small spates in the River Axe, using flow data for a number of years, including 1959 and 1976, which were particularly dry years.
Sea trout, as well as salmon, have been considered because of the fear expressed that low prescribed flows might not be adequate for the movement of the fish into the river. Data on rates-of migration are not considered further in this report.
