    Creek Bend Pond by Lisa O'Brien

    Warm temperatures have had frogs breeding and seeing tadpoles early. Water is clear and seem healthy from the macroinvertebrates we have pulled from the water. Cl values trended high beginning in March after falling from Nov-Feb. Did not see a decrease in levels yet. We have had quite a bit of rain, wonder if culvert to pond has caused higher levels of Cl to enter.

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

    After it rained, I took this sampling toward the far corner and it seemed to have more chloride levels compared to the nearest area, around the 50s weather!

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

    There was so much green stuff due to the rain? After the rain, it was around the 50s and I took sampling near the parking lot which showed least amounts of chloride.

    Bayou Path Dr Stream in Atwater Subdivision by Lisa Hjorth

    Stream was free of any debris or litter. The stream was flowing fast. You could not see the bottom. The chloride reading was rather faint compared to earlier tests, so I included a close-up picture to show the peak better.

    Although 28 was enter as the value for chloride, the actual value is slightly less but the conversion chart only goes as low as 28.
