‘First Flush’ Water Quality Monitoring Results Are In

The storm that swept through Nevada County between the 23rd and 25th of October dropped between seven and twelve inches of much needed precipitation. This rainfall has led to, among other things, increased flows in the Yuba River and SYRCL’s ‘first flush’ event.

We sat down with our resident hydrologist, Karl Ronning, to learn more about this ‘first flush’ event and to discuss the results of our water quality monitoring.
