FISH MOVEMENT RECORDED AT AUTHORITY FISH COUNTERS - \°&S" 4.1 River Lune Forge Weir counter: prolonged periods of breakdown in 1985 due mainly to failures in the power supply. The figures obtained are therefore well below the true figures and interpretation should therefore, be cautious. A new supply cable is currently being laid. ** Skerton Weir counter monitors movement of fish at low flows only; the count is ••. incomplete. -28 - 4.2 RIVER KENT Basinghyll Counter, Sedgwick This counter was destroyed by a flood on 21st December 1985 and plans are in hand to re-build it at a different location. - 29 - 4.3 RIVER LEVEN Haverthwaite Counter (Eels dam) - 30 - 4.4 RIVER DUDDON Duddon Hall Counter 31 - MONTHLY TOTAL 4.5 RIVER RIBBLE CATCHMENT - 32 4.6 RIVER WYRE Garstang Counter 4.7 RIVER DERWENT Yearl Counter. Because of various operational problems, no reliable data from this counter are available for 1985. 33 5. COUNTS OP SALMON AND SEA TROUT SPAWNING REDDS 5.1 North Cumbria Note In all these years, high and turbid river conditions during the autumn made redd counting difficult or impossible, and the figures given above are undoubtedly incomplete. - 34 - 5.2 West and South Cumbria Note High river levels for much of the spawning season resulted in incomplete counts on many rivers in 1983, and it is thought that many more fish spawned in the Rivers Cocker and Derwent than the bailiffs were able to record.
