Lake Water Chemistry

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Lake water chemistry measured at the outflow of Tamarack Lake.

This datatable is part of the Water Chemistry in Streams, Lakes Wetlands and Groundwater near the KBS LTER dataset. Water chemistry is measured in diverse surface waters and in two water supply wells in the vicinity of the KBS LTER. This dataset includes sites sampled over time (streams, wells, some wetlands) as well as wetland sites sampled once or a few times. A separate dataset includes soil water chemistry sampled from the LTER treatments.
