Water is on everyone’s mind these days, and it doesn’t do us much good if it’s polluted! Come help with a creek survey and find out how clean the water is in the Arroyo del Valle. We will take scientific measurements and then do a benthic macroinvertebrate survey (also known as a waterbug hunt). Good for ages 8 and up. RSVP required by calling (925) 960-2400.
Join Ranger Darren Segur at Sycamore Grove Park, Arroyo Road Entrance (5049 Arroyo Road).
