This data package was created 2025-01-14 13:47:36 by NPSTORET and includes selected project, ___location, and result data.

Data were collected in response to recommendations in a Water Resources Scoping Report, to provide essential information for revision of the park's General Management Plan, and to develop and implement its GPRA goals. The goal of the project was to expand the water resource inventory and monitoring programs in Shenandoah National Park from the lower stream reaches of the park to include headwaters and springs and examine the newly identified threat from mercury deposition.

Data contained in Shenandoah National Park - University of Virginia NPSTORET back-end file (NPS_UVA_NPSTORET_BE_20250108.ACCDB) were filtered to include:
