    North Branch Chicago River at Edgebrook Woods by Alan Matson

    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

    Terrace View Park Pond in Lombard, IL by Tony Ream

    Had a lot of snow the last couple days with the snow plows and salters out in force. Had a lot of snow and caught the back part of the storm with a very slushy mix. This is the first time I have seen the water actually flowing. The pond is frozen with the water moving underneath toward the outlet.
