SUMMARY:Explorations with Your Riverkeeper: Shenandoah Snorkeling Paddle w/ Shenandoah Riverkeeper
DESCRIPTION:Friday\, \n\n\n\n\n\n\n\n\n\n\n\nPhoto Credit: Alan Lehman\n\n\n\n\n\n\n\n\n*RESCHEDULED FOR AUGUST 21\, 2026* \n\n\n\nReady to see the Shenandoah River from a whole new perspective? Join Shenandoah Riverkeeper Mark Frondorf for an unforgettable paddle-and-snorkel adventure on the beautiful South Fork of the Shenandoah River. \n\n\n\nThis isn’t your typical float trip. We’ll paddle a scenic stretch of river with plenty of stops to slip into the water\, mask up\, and explore what’s happening beneath the surface. The Shenandoah is full of surprises\, and snorkeling reveals an entire hidden world of fish\, aquatic life\, and river-bottom habitats that most people never get to see. \n\n\n\n\n\n\nAdding to the adventure\, we’ll be joined by Mike Selckmann\, Associate Director for Aquatic Habitats at the Interstate Commission on the Potomac River Basin (ICPRB). Mike will help us uncover the fascinating story of freshwater mussels—one of the river’s most important and most overlooked creatures.  \n\n\n\nThese remarkable animals are natural water filters\, with a single mussel capable of filtering 5-15 gallons of water every day. Historically\, healthy mussel beds helped keep the Shenandoah and Potomac rivers clean and thriving. Today\, however\, robust mussel populations on the Shenandoah are rare. But efforts are underway to turn that around. \n\n\n\nWhere did all the mussels go? Mercury contamination? Increased sediment? Rising water temperatures? \n\n\n\n\n\n\n\n\n\n\nMike Selckmann of ICPRB talks about the mighty mussel to snorkeling attendees while SRK Mark Frondorf listens intently in the background. Photo Credit: Alan Lehman\n\n\n\n\n\n\n\nThose are exactly the kinds of questions we’ll explore together as we snorkel\, observe\, and learn about the challenges—and hope—for restoring this critical part of the river ecosystem. \n\n\n\nBecause this trip has a strong community science and exploration component\, we ask that participants feel comfortable swimming and spending time in the water so we can focus on discovering mussels and learning about the river’s underwater world. \n\n\n\nIf you’ve ever wondered what lies beneath the surface of the Shenandoah\, this is your chance to find out. \n\n\n\nSpace is limited\, grab your snorkel gear (or use ours) and reserve your spot early. Come join your Riverkeeper for a day of paddling\, snorkeling\, and river discovery. \n\n\n\nWe can’t wait to see what we find down there. \n\n\n\n\nREGISTER HERE\n\n\n\n\n\n\n\n\n\n\nTRIP DETAILS\n\n\n\n \n\n\n\n\nArrival Location:Downriver Canoe Company884 Indian Hollow RoadBentonville\, VA 22610\n\n\n\n\n\nArrival & Check in Time: 10:00 am\n\n\n\nShuttle Departs to Put-In: 11:00 am\n\n\n\nEstimated End Time: 3:00 pm\n\n\n\nPaddle Level: Intermediate\n\n\n\n\nIncluded with each registration: \n\n\n\n\nRiverkeeper Leader\n\n\n\nRental canoe or kayak\n\n\n\nPaddle insurance\n\n\n\nPersonal flotation device for the day (with rental)\n\n\n\nSnorkel equipment\n\n\n\nShuttle Service (if applicable)\n\n\n\nSRK Swag Bag\n\n\n\n\n\n\nWHAT TO BRING:\n\n\n\n \n\n\n\n\nPacked lunch\n\n\n\nReusable water bottle (please no single-use plastic bottles or glass) \n\n\n\nWear proper footwear.

Join Hispanic Access Foundation and Waterkeeper Alliance for an accessible\, community-focused webinar designed to make PFAS testing easier to understand\, no scientific background required. \n\n\n\n\nThey will explain what PFAS testing is\, how it works\, what you need to know before testing\, and how to make sense of the results. You’ll learn about the testing process in plain language\, from collecting a sample to receiving your laboratory report. \n\n\n\nPotomac Riverkeeper Network’s own Upper Potomac Riverkeeper\, Brent Walls will join the conversation as a panelist to discuss how we incorporate Cyclopure test kits into our work. 🧪 \n\n\n\nWhether you’re a community member\, local organizer\, environmental advocate\, or simply want to know more about the water or environment where you live\, this webinar will give you the information and confidence to take the next step. \n\n\n\n\nYou’ll learn: \n\n\n\n\nWhat PFAS are and why communities may want to test\n\n\n\nHow to collect samples for PFAS testing\n\n\n\nHow PFAS are detected and measured\n\n\n\nHow to understand your test results\n\n\n\nPractical tips for communities conducting their own testing\n\n\n\n\nNo scientific experience is necessary. This webinar is designed to make PFAS testing understandable and accessible to everyone. \n\n\n\nThis webinar will be bilingual (English/Spanish)\, with live Spanish interpretation provided. \n\n\n\n \n\n\n\n \n\n\n\nWednesday\, September 9\, 202612 p.m. – 1:00 p.m. \n\n\n\nFREE Zoom Webinar \n\n\n\n\nREGISTER HERE

SUMMARY:Mussels in the Mainstream
DESCRIPTION:Photo Credit: Ashley Flores\n\n\n\n\n \n\n\n\nOysters get a lot of buzz in the Chesapeake Bay region\, but freshwater mussels provide many of the same ecosystem services in the 64\,000-square-mile watershed that feeds into the Bay. These unsung water quality and habitat heroes are finally getting some mainstream recognition\, with their inclusion in the 2025 Chesapeake Bay Watershed Agreement and restoration efforts ongoing in streambeds across the watershed. \n\n\n\nJoin the Chesapeake Research Consortium on Wednesday\, September 23rd from 12-1pm to hear how science\, innovative approaches\, and watershed policy are converging to support populations of native freshwater mussels. \n\n\n\nPotomac Riverkeeper Network’s own Staff Scientist\, Evan Quinter will join the conversation as a panelist to discuss our 50 Million Mussels Project and our work to repopulate the Potomac and Shenandoah with these small but mighty creatures! \n\n\n\nSpeakers: \n\n\n\nEvan Quinter\, Staff Scientist\, Potomac Riverkeeper NetworkJamie Brunkow\, Director of Advocacy and River Ecology\, James River Association \n\n\n\n \n\n\n\nWednesday\, September 23\, 202612 p.m. – 1:00 p.m. \n\n\n\nFREE Zoom Webinar \n\n\n\n\nREGISTER HERE
