Yesterday August 11th, during our regularly scheduled water quality monitoring session I obtained a secchi disk reading of 5.45 meters (17.88 feet) which is a new transparency record for Clary Lake. The previous record was 5.30 meters observed on September 14, 1994. You can see today’s data point sitting all by it’s lonesome, high on the right side of the above chart, and noticeably higher than any other dot on the chart. Kelsie French who normally accompanies me wasn’t able to join me today so my wife Margaret came out to help. She tried her hand at taking a secchi disk reading and got 5.25 meters, only 4 inches shallower than my reading.

We also took a 4 meter core water sample for Total Phosphorus testing, our third TP test of the summer so far, We’ll take another one in mid-September. Not surprisingly given our clear water this summer, the first 2 TP tests came back at 0.012 mg/L which is exceptionally low for Clary Lake.

Our water quality data is available on our Clary Lake Water Monitoring Data page.
