Stream sampling stations for watershed study, Chesapeake Bay

Stream sites sampled by automated sampler or spot sampling in the NSF watershed study. The sites are grouped in 17 regional clusters throughout the Chesapeake Bay watershed. Sites were mapped in the field onto USGS 7.5' topographic maps, then digitized from those maps into a series of ARC/INFO point coverages (one for each cluster).
