Water temperature and streamflow intermittency are critical parameters influencing aquatic ecosystem health. Low-cost temperature loggers have made continuous water temperature monitoring relatively simple, but determining streamflow timing and intermittency using temperature data alone requires significant and subjective data interpretation. Electrical resistance (ER) sensors have recently been developed to overcome the major limitations of temperature-based methods for the assessment of streamflow intermittency. This technical note introduces the STIC (Stream Temperature, Intermittency, and Conductivity logger); a robust, low-cost, simple to build instrument that provides long-duration, high-resolution monitoring of both relative conductivity (RC) and temperature. Simultaneously collected temperature and RC data provide unambiguous water temperature and streamflow intermittency information that is crucial for monitoring aquatic ecosystem health and assessing regulatory compliance.

Goal: Reduce the impact of urban runoff and aseasonal flow on the highest priority MSP species and riparian habitat so that species can presist over the long term (>100 years) in areas upstream and downstream of urban land uses.
Management units: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
Continue USGS research study using STIC sensors to measure water temperature and presence in chosen stream channels. The final report should include an analysis investigating the relationship between upstream urban land uses and the number of days with water present. The data should be available in a format that will aid the creation of a hydrologic management plan.
