Long-Term Ecological Research (LTER)/CDR030: Groundwater Dynamics and Chemistry at Cedar Creek Natural History Area

LTER - Long-Term Ecological Research Program/Cedar Creek Natural History Area (CDR) LTER/CDR030 [Summary adapted from the LTER Core Data Set Catalog]: Eighty-seven piezometers (cased bore holes) were installed along topographic transects within the Cedar Creek Natural History Area. Depth to water table is measured at each well at a monthly to quarterly interval. Water samples are collected periodically and analyzed for pH and major cations and anions. The Cedar Creek Natural History Area (CCNHA) is a 2200 hectare experimental ecological reserve operated by the University of Minnesota in cooperation with the Minnesota Academy of Sciences. CCNHA is located in Anoka and Isanti Counties north of Minneapolis/St. Paul. The site was established in 1940, was designated a National Natural Landmark by the National Park Service in 1975. In 1977 it was included as an Experimental Ecology Reserve in a proposed network, and in 1982 it was one of 11 sites in the U.S. selected by the National Science Foundation for funding of LTER.
