The quantab results are below the scale so the lowest value of ppm was recorded.

Timber Ridge Forest Preserve by Andy Culbertson
The trail was mostly dry. I could hear the water rushing as I approached the bridge. The noise was partly from a short waterfall at the point the creek disappeared from sight upstream from the bridge. I hadn't noticed it before, so it might be new. The gravel lot I usually park in now has "not a parking lot" signs, so I parked at Kline Creek Farm up the trail.

Bayou Path Dr Stream in Atwater Subdivision by Lisa Hjorth
Water levels in the pond (inflow) were higher than previous test dates. Although plant vegetation blocked some of the flow at the yellow strainers (inflow), there still was a fast water flow (outflow) at the test site. The increased water level was due to normal seasonal rainfall.

Lake Killarney outlet dam (Cary, IL, 60013) by Eberhard Veit
Chlorides are very constant. Mainly stemming from groundwater load entering the lake. All side streams entering the lake are higher than the lake. Even my drinking water well is around 300 PPM CL- . The creek entering from the Hollows in around 200 PPM and other inflows are between 200 and 330 PPM

Creek Bend Pond by Lisa O'Brien
Typical spring weather, warm/cold/windy with some rain or snow. Even with rain, the pond doesn't appear to have increased water levels. The exit to the creek does, however, look to provide easier flow into the creek from previous years. Have seen turtles, ducks, geese and other birds at the site.

Big Hollow Creek in Iris Park by Robert Rowe
The stream where I sample is now the site of some major modifications, what appears to be plans to install concrete and gravel-cage bank stabilization. Heavy equipment has been driving in the stream bed.
