Synoptic Monitoring Event on May 28, 2025
for Direct Streams under Base Flow conditions
Notes: Dean's Creek Dublin Hill (DCDH)- Near record monthly rainfall preceding sample date. Ag fields very wet. Flow = about 1.5 ft3/s; Dean's Creek at 34B (DC34B)- Near record monthly rainfall preceding sample date. Very wet farm soils. Flow at about 1 ft3/s; Paines Creek Rafferty Road (PCR)- Near record monthly rainfall prior to sample date. Very wet Ag fields. Flow = about 1.7 ft3/s. Despite rainfall prior to the event, all volunteers reported that water appearance was "clear" and flow conditions were either "base flow" or "moderate".
