Installation and Calibration of Level Loggers to Assess Stream BMP Effectiveness

Description
Urbanization and development have degraded stream health and increased pollutant flux. Recent efforts have included stream restoration to stabilize the channel. Additionally, channel restoration qualifies for BMP pollutant reduction credits. However, the effectiveness of channel restoration in achieving flow and pollutant reductions is uncertain. To assess flow and flux impacts, we installed level loggers at three sites for which channel restoration is to be conducted within the next two years. Level is being monitored to collect baseline data prior to BMP installation. Discharge rating curves are being developed for all three sites using the salt dilution and flow-weighted methods to determine the best calibration approach for the streams selected.
