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) .
REDOX was 262 mv. This is the beginning of REDOX/ORP being taken in Loon Lake.
Lake sampling taken today, all similar characteristics, demonstrated that this location is a good location that is representative of other locations in the lake.
It will be the prime location for testing on Loon Lake.
