10 degree surging flow
Wetted width 18cm
Depth 1.3cm. Chlorine 0.0
Flow 6L 1.95 sec capture 90% of flow.
With testers Susan G. and Finn A.
Water had slight cloudiness, but secchi disk clearly visible in tube, turbidity <14 NTU.
Very high energy flow. Grab sample collected ~10m from concrete slab discharge point - unable to approach pipe due to safety. Lower conductivity due to increased water volume. This location more turbid than other locations sampled in same time period. 6PPD-Q sample collected.
Grab sample collected in a cup from discharge point at bottom of concrete slab in the plunge pool.
Conductivity 326 uS at 18.1 deg C.
Water column completely clear - 14 NTU (unable to enter "<" symbol).
YSI probe sampled the east side of plunge pool. YSI readings: Water temp: 16.8 deg C; DO: 10mg/l; Spec Cond: 345; Cond: 305; ph: 7.29; TSS: 124; Turbidity: 5797 NTU
Turbid water. Gray foam on water. Slight smell of sewage.
Water is gray, high turbidity. Visibility is about half a metre foam accumulating. Suspended sediments. Slight smell of soap. BC metre has water temp reading of 8.6°C TDS 250 ppm.
Good volume of water. Slightly cloudy water column.
For comparison, measurement also taken in mainstem. Conducivity: 538, TDS: 267/
At the time the sample was taken, it had just started to rain in the past hour after approx 2 days of no rain.
High turbidity; water appeared gray/black; visibility <1 cm
water relatively clear, .75m visibility. currently only a light drizzle but water still discharging forcefully, splashing about .5 m height when it hits riprap
Water is murky with brownish green cast, very turbid
