BcCZOII member, Nate Rock, was able to access Lower Gordon Gulch via Golden Gate on 17 September 2013 only to find that the GGL gauge had been destroyed by the epic Boulder County floods. Fortunately the ISCO did collect 24 samples every 2 hours beginning on 11 September and the time lapse camera (see below) was also still functioning. These measurements will provide useful information to the BcCZOII as they begin to piece together data collected during the storm.
The ISCO has a new battery and is sampling every 4 hours. Nate was also able to get a pretty good manual discharge measurement and marked the high flow points around the gauge.
Nate is planning to head to Upper Gordon Gulch in the morning (Sept 18th) and will update when he is back in Boulder.
Gordon Gulch is a relatively small basin (3.7617 km^2) in the mountains above Boulder, Colorado at an elevation of 2588 m. The CZO camera captures the influx of the water at the stream gauge and then cover and wash the gauge away (frames from Sept 9-17 2013).
