Notes

Another big snow ending yesterday. Lots of salt spread on our local streets near the river. So chlorine should be increasing, and up 100 since last week!
Now very cold. Ice crystals forming on the river and condensing to slush. The banks are starting to freeze. Whole river should freeze over next couple of days
