Snapshot Day Results: Transparency
See Full Monitoring Results and Maps Below
Transparency tells us a lot about water quality.
When rain falls, water drains off the land, collecting loose soil (sediment) and other pollutants as it goes, carrying it into the nearest creek or river and eventually into our lakes. Sediment collects on the bottom of lakes and streams, reducing their depth and affecting their overall health. Transparency reflects how deep down we can see through the water. The deeper we can see, the less particles of sediment and/or algae are present. Poorer transparency indicates more particles, and the water may appear cloudy instead of clear.
On Snapshot Water Monitoring Day, volunteers measure transparency at sites across our watershed. While there have been areas of moderate to critical concern over the last several years, transparency levels across the watershed are generally within a normal, healthy range.

2020 Transparency Results
In 2020, transparency across the watershed was generally good, with a few small areas of low to moderate transparency.
2019 Transparency Results
2019 monitoring found just two areas of critically low transparency, but slightly more moderate levels than the previous year.
2018 Transparency Results
In 2018, we found several areas of moderate to critically poor transparency across the watershed.
2017 Transparency Results
2017 monitoring showed a few areas of critically low transparency, with the greatest concentration just northeast of Warsaw and Winona Lake.
