Over the last 100 years our modern society has learned a lot about how rivers and riparian systems function and why it is important to keep natural systems healthy. We now know that introducing non-native species can harm native species, that straightening a river channel can have damaging impacts for downstream landowners, and that removing riparian vegetation can cause serious erosion problems. But because it took many decades to learn these things (and because we are still learning), a lot of damage has been done to the river. To learn about the various human activities that have changed the river over the last 100 years and the consequences of those changes, click on the buttons below.
