Survey of Life in Allestree Park Lake, 4th June 2011


water quality survey 2010.06It was beautifully sunny and warm, just as well as Pat Sear had an OPAL Water Survey to carry out to check the quality of the water in the lake and to get some idea of life in the lake. Pat asked if Bill Grange could be present to identify as much of the nature retrieved by dipping, as possible, myself to try and get some photo's. As one of the rangers, Mike Day came to help having a good knowledge of the park and lake. John Menzies in his capacity of the new chairman of FOAP came along to see what we turned up and I suspect enjoyed it more than he had anticipated ! The results of the dipping were rather mixed. There were Daphnia by the thousands, which is good, and there were quite good numbers of immature water boatmen. There were also two species of water snail. But species we could have expected were absent. Although I have found the odd adult Mayfly we didn't find any larvae and only one Caddis Fly larvae. Neither did we net any water beetle species.The biggest and most entertaining species we saw was a male Broad Bodied Chaser. The speed and agility of this spectacular and wonderful dragonfly dwarfs any of man kinds achievements.We await the results of the metals test from the sample of mud Pat has sent to the lab. Hopefully, given the location of the lake etc., this will be good. Steve Plant
