With the warming trend and melting snow of late, I resumed making water level measurements yesterday but with the snow storm due in this weekend I suspect I’ll knock off again for a while. I had to remind myself the other day why I’m making water level measurements: primarily I am interested in modeling the complex hydrological system that is Clary lake. With its variable inflows from runoff and ground water and variable outflows depending on the status of the dam’s gate, how the lake rises and falls at any given time is anything but obvious. There’s a lot to ponder and a lot to learn.
Jane Chase has given me some more pictures that I will scan and add to the Chase Family Archive when I get a chance. Also, Colin Caissie has given me a CD full of photographs he took last week while cross country skiing down the channel to the dam. He is particularly concerned about the impact that ice flows are having on the shoreline: as result of the historically low water levels, ice flows are plowing up soil, sediments, and sensitive wetland vegetation around the lake. This has already resulted in erosion and sedimentation of the waters of Clary lake as well as the Sheepscot river, a serious condition that will accelerate this spring when ice and snow melts and outflows increase. If you will recall, I expressed similar concerns in a recent post with accompanying photographs in the Winter 2013 album. I’ll post some of Colin’s pictures soon.
