    Veteran Acres - Sterne Woods (Oakwoods Lodge) by Far Syed

    The weather was great around 75 degrees. There were geese on the other side, and the water was calming, but high chloride levels were still an issue!

    Lippold Park - West Entrance by Far Syed

    The weather was so great at 74 degrees. The water was sparkling, and the geese were enjoying the nice breeze and water. It was a calming site, but the chloride was high as the geese were far away from it!

    West DuPage Woods by Ruth Gauss

    I finally created a water gathering device so that I didn't need to step into the river to collect the water and then fight my way back up with mud on my boots making it difficult to not slide back in. I went to American Science and Surplus and found a telescoping alligator clip ($3.25) and a plastic test tube ($.40) and used the alligator clip to hold onto the top edge of the test tube - the hardest part was getting the tube to submerge and fill with water since it was light enough to float on top of the water. It was a lightweight and easy to carry solution that I've been thinking about trying to create since I started monitoring in 2023.
