Twice a year, members of the Cutthroat Chapter of Trout Unlimited walk through parts of the South Platte River to access submerged data loggers, bring them to the surface and download the last 12 months of data. We have three submerged data loggers and one ambient air logger that have to be found. Accessing the data loggers in the river requires remembering where they are, finding the rebar post and then unscrewing old hose clamps. Ray leads the group just upstream of Deckers. Below Jim and Bill are using a “hydroscope”, aka a clear piece of Tupperware, to see into the river so Bill can open the hose clamps and bring the data logger to the surface. The group pulled the last data logger that, unfortunately, would not communicate with our App. After the work was done everyone spent a few extra hours fishing the canyon. A few of us will have to return shortly to install a new data logger.
