    Timber Trails Park pond by Michelle Besch

    Beginning to drizzle. Top inch or two was liquid, however, underneath is still has some ice. Areas with more ice on top around collection site. Hard to tell if what I collected was just from rain as I couldn’t get deeper underneath from my typical access point.

    Lippold Park - West Entrance by Far Syed

    Every time I tried to take a sample, the water was icy, so now I managed to get a water sample, since there was some open cracks! The chlorine levels were either high or low, depending on the weather, and it was around 45 degrees, which was higher.
