Although the reservoir is now used as a trout fishery and as a supplementary water supply for the Thirlmere Aqueduct, Dubbs Reservoir was originally built to supply water to Windermere. I could be totally wrong here, but I suspect that prior to the intrusive looking dam being built, there may have been an obviously smaller, but much more attractive little tarn at this spot.
Each time I've visited, the weather has been somewhat less than perfect, so you could say that I haven't actually experienced the place at its best. As I've approached the tarn there's always been an underlying feeling that I'm going to be let down as far as looks go, when I get there however, I begin to think, "perhaps it isn't that bad after all". I know it doesn't begin to compare to many of the other tarns in the district, but, if you consider that the tarn is in effect 'practical rather than pretty' then the initial disappointment is soon forgotten.
The easiest way to reach the tarn is to park at the point where Dubbs Road (track) joins Moorhowe Road. From there simply follow Dubbs Road up to the tarn. Alternatively the tarn can be included in a much longer walk taking in some of the lovely countryside in the area.
