  • Hi Elle,
    Vented pressure sensors going to a logger box out of range of flow is one option, Ultra sonic distance measure is another, which avoids problem of freezing etc. Both could easily give you continuous, real-time measures which you may find much more valuable than peak stage only. Not sure about your budget, but driving to all the stations…[Read more]

  • Hi Kevin,
    I can’t answer you electronics questions, but will comment on your sensor deployment. Placing stream sensors in an enclosure may cause some issues. First, an enclosure with small holes will tend to fill with sediment when the speed of the water slows going through the case. Depending on the types of sensors, they need more open space…[Read more]

    What is a good way to gage a stream without using a weir or an engineered flume?  How about this stone control structure / flume?

    Having a stable control  is invaluable for developing a good stream flow r […]

    • Nice job Dave! I really like the aesthetics of this one, and the narrow throat will definitely give it the low end sensitivity that you’re looking for.
