Hydrologic and water-quality data for two small watersheds on Catoctin Mountain, North-Central Maryland, 1987-93

Abstract

Hydrologic and water-quality data were collected during 1987-93 from a precipitation-collection station and from two small watersheds on Catoctin Mountain, north-central Maryland, as part of investigations of acidic deposition and episodic acidification and their effects on streamwater quality. Detailed descriptions of the site instrumentation in the two watersheds, field data-collection techniques, and laboratory methods used to conduct the studies are included and the information is summarized in tables. Data were collected on precipitation, throughfall, soil water, ground water, streamwater, and other surface and ground waters that were sampled during biannual synoptic surveys.
