Long-Term Ecological Research (LTER)/AND005: H.J. Andrews Watershed Streamflow Summaries
Listed in NASA Earthdata CMR
LTER - Long-Term Ecological Research Program/H.J. Andrews Forest (AND) LTER/AND005 [Summary adapted from the LTER Core Data Set Catalog]: Streamflow from selected small watersheds has been continuously monitored at the Andrews since 1953.
Description
The objective of these studies have been several-fold: to evaluate long-term changes in hydrology associated with various management treatments, notably clearcut logging; to provide baseline data for affiliated nutrient, water chemistry, and sediment transport studies; and to characterize the hydrologic regime of old-growth forests at different elevations.
The nine sites consist of three sets of paired watershed experiments (WS 1, 2, 3; 6, 7, 8; and 9, 10) and Mack Creek, a larger (6.0 km2), old-growth watershed. Drainage areas for the paired watersheds range from 9 to 100 ha and elevations range from 460 to 960 m. Watersheds 2, 8, and 9 are forested controls.

Treatments include 100% clearcut (WS 1, 6, and 10), patch cut with roads (WS 3), and shelterwood cut (WS 7). All treated sites were calibrated against controls for at least 8 years prior to treatment. Streamflow is measured continuously with Leopold-Stevens A-35 recorders.
The master stream for the H.J. Andrews, Lookout Creek, has a U.S. Geological Survey stream gauging station with a drainage area of approximately 63 km2; records for this site are maintained by the U.S.G.S. The Andrews Forest is in the western Cascade Range of Oregon in the 15,800-acre drainage basin of the Lookout Creek, a tributary of Blue River and the McKenzie River. The area elevation ranges from 1350 feet to 5340 feet and contains excellent examples of Pacific Northwest conifer forests, wildlife, and ecosystems.
