The temperatures of four Pennine streams
Four streams in Teesdale (UK) were studied over a period of two years. The biological implications were studied by using the stream temperatures to predict both the times of brown trout eggs to hatching. Intragravel and stream water temperatures were compared for a spawning riffle in Great Eggleshope Beck. The effect of vegetation shading on water temperature was studied at Thorsgill Beck, which runs through deciduous woodland. An analysis was made of the time of day at which the maximum and minimum temperatures occurred in Carl Beck. Methods of calculating mean daily temperatures were examined. Estimations using the mid-point of the maximum/minimum range were usually higher than those from hourly temperature readings. (PDF contains 34 pages)
