Abstract:
This Report is intended to provide a short but fully referenced account of available information on the environment and ecology of Haweswater. Deductions are made regarding the susceptibility of the lake to change, either from natural or man-made influences. Haweswater is now one of the larger and deeper Cumbrian lakes, and its drainage basin one of the least populated. These features are not original, but result from a reservoir-darn construction that subsequently deepened the earlier lake by 29 m and flooded the adjacent valley floor. Water storage in the much-enlarged lake is exploited through an aquaduct to the south. Inputs from the immediate catchment are selectively augmented by aquaducts from the water-bodies of Wet Sleddale and (since 1971) Ullswater. Nevertheless very extensive draw-downs still occur in dry summers, and occasion public interest from the exposure of old relics. Although the lake has not received intensive scientific study, a considerable amount of ecological information exists - chiefly from the records of the Freshwater Biological Association. Such information is summarised in this Report. Particular attention is given to susceptibility to change, that might arise from altered usage of land (e.g. afforestation) or water (e.g. fish-farming), and affect both water supply and conservation interests.
