The lake was mostly frozen over, but by moving about 100 yards away from my usual site, the ice was thinner, and I could get water. There was significantly less chloride than any other time I've tested this lake.

I did two tests today to check accuracy of the test strips. It rained pretty hard for about 30 minutes just after I started the first test. I waited until that was over to do the second test. The second test came out a little higher, and with rounding up, I reported it .2 Quantab Units higher (14 ppms). The first test was at 154 and the second was 168, so I averaged these and reported 160 in my results above.
Please let me know if I need to do this another way. I wasn't able to do two separate observations.
