Loon Lake
Ontario, Canada
Open lake approximately 5 meters from shoreline at 3 meters depth. Sand bottom.
Lake flow direction at this point is very low toward NE.

Phosphate 0.25 mg/L; ORP 151mV; chloride 6.0 mg/L (titration); Water drawn from lakewater pump at a depth of 2.0 meters.
Would prefer a higher ORP value.
Chloride concentration measured with TAYLOR K- 1598 drop test kit (NEW). This is titration, not by any calculation.
Kit is very easy to use, with good instructions.
For a senior individual, who gets no funding for the hobby of water testing, this kit, while apparently very satisfactory, is somewhat expensive.
Chloride derived from product of salinity and percentage ionic concentration of chloride (6%)
Awaiting chloride drop test kit from Lowry & Associates
This records the start of measuring Salinity with a new AZ 8372 Salinity pen.
Water filtered through 5 micron filter.
ORP = 185 mv. This is a bit lower than normal. DO is higher than normal. This bears watching.
Hydrogen Sulphide 0.0
Nitrite and nitrate = 0.0
Chloride is higher than last reading. Bears watching.
New EC METER BEING USED. COULD ACCOUNT FOR ANY DISCREPANCY IN TDS AND HENCE IN Chloride at 19% of TDS.
Ice out April 3/24. These readings following a 4 day Colorado low with winds of 90 mph creating 5 ft waves crest to crest .. adding oxygen to the water. A substantial drop in Chlorides to 10.83 from 12 mg/l due to somewhat milder winter and the MTO using pre-wetted salt and checking periodic spreader calibrations.
ADDED MEASUREMENT: ORP = 261 mv.
Readings taken at equivalent location of Patterson’s dock for purposes of recording any decline or stability in chlorides. Result that chlorides seem to have stabilized and not decreased further.
Any dissolved oxygen level is measured in mg/L using titration.
REDOX (ORP) remains good at 275 mV. I regularly now test for ORP.
Chloride is calculated from TDS, using a linear mathematical developed relationship. As an approximation, for quick reference, chloride is about 19% of TDS.
ORP was 305 mv.
Dissolved Oxygen measured by titration.
Hydrogen Sulphide was 0.0 mg./L
Chloride by test strip was approximately 25 mg/L
Chloride by percentage of TDS was 12.1 mg/L (acceptable accuracy) .
