Year 2019, 2020 and 2021 continuous measurements, every 15 minutes, were made of depth and stream temperature in a small headwater stream, Saw Mill Brook, Burlington, MA, draining a highly suburban catchment (72% residential) in the Ipswich River watershed. Discharge is determined from stage using discharge vs stage regressions.
HOBO data loggers were used exclusively these 3 years to monitor stage height and water temperature.
HOBO: Depth and water temperature are recorded by the HOBO data logger. Depths are corrected for barometric pressure changes using readings in an additional HOBO datalogger deployed at Marshview Farm. The HOBO is deployed in a a PVC tube, which was attached to ree-bar driven into the stream bed. The PVC tube has holes drilled to allow adequate water circulation.
NOTES AND COMMENTS:
Beaver activity has been continuous since 2010, and so no rating curve information is available. However stage continues to be monitored, so changes due to storms, and/or beaver activity, relative to the channelized state are useful information
1-- Discharge will be calculated when a new rating curve is developed.
2-- Beaver activity
