    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.
