    Center Deep Spot by Mike Grinnell

    Nephelometer voltage 4.38 equals approx 0 NTU. THIS IS A CHANGE FROM 4.46 volts which corresponds to slightly more turbid water. But for this freshwater lake, I will accept virtually non turbid water. Surface pH was 7.62 and surface TDS was 68. Bromine and chlorine test slightly present with Taylor strips. Doesn’t make a lot of sense but chlorides are in the lake and have been slightly increasing yr/yr. Likely due to winter salting. No real concerns at this time.

    DO was 9.07 mg/L at 5 meters and 7.62 mg/L at 16 meters depth. Used the MOECP YSI dissolved oxygen meter.

    Rafferty Dam by Danica Milatz-Donnelly

    Beautiful, sunny day. Lots of minnows in the water. Also saw dragonflies and seagulls.

    Slocan Lake by Cei Sullivan

    Was not able to get the water depth measurement due to wind

    Nitrate by titration between 2.5 and 5 ppm. Increase from previous reading. Not a trustworthy reading because of difficulty reading colour card. Will monitor. Hydrogen Sulphide reading was 0.0. Noted was slightly more algae suspended in the water. Turbidity not electronically measured at this time due to continued development of the home made Nephelometer. I have developed a cubic quadratic equation for relating sensor output voltage to % of sensor detection range. The units in that range relate linearly to the actual NTU.
