RESPONSE TEMPERATURE MODELING AND ITS POTENTIAL ROLE IN TMDL DEVELOPMENT
Abstract:A simple, spreadsheet-based, time series response temperature model (RTM) was developed as part of a thermal mixing zone study performed at FirstEnergy Corp's Toledo Edison Bay Shore Station, located on a peninsula between the Maumee River and Maumee Bay in the western basin of Lake Erie, near Toledo, Ohio. The RTM was calibrated to a short intake temperature record (83 days spanning the summer of 2002) and the resulting model was then applied to the 48-year record of meteorological observations for the local National Weather Service station. The calibrated time series model suggests that natural water temperatures in Maumee Bay occasionally exceed water quality standards (WQS), even in the absence of anthropogenic heat sources. The RTM has potential value in the development and evaluation of temperature TMDLs where long-term water temperature data are not available.
