Yesterday was coooold, but it was time for our quarterly stream monitoring! This time, we had a great group of volunteers, led by Dan Schwartz of the Northern Virginia Water and Soil Conservation District. The results were typical -- Difficult Run in this area isn't dead, but it's not totally healthy either. We still need to pay attention to urban stormwater runoff, both quantity and quality.
What did we find? LOTS of netspinners, (photo credit: Aquatic Insect of Central VA website)
