ABSTRACT:
	Water samples have been collected for analysis of water stable isotopes (O18/16 and H2/H1) at different locations in the HJ Andrews Experimental Forest and over different periods since 2014 in the HJ Andrews Experimental Forest. The database includes: 1) grab samples collected over the stream network of the Andrews Forest on multiple sampling campaigns during various flow conditions. In each of the campaigns, the samples were collected at approximately 50–100-meter intervals in 1st–5th order streams across the network; 2) water samples collected in the Andrews Forest every 1–3 weeks between 2014 and 2018 in streams (Lookout Creek, Mack Creek, McRae Creek, WS01, WS02, WS07, and WS08) and bulk precipitation from benchmark meteorological stations (PRIMET, MACK, and H15MET) between 2014 and 2023; 3) stream and precipitation samples collected in the Andrews Forest at high temporal resolution during discrete storm events at Mack Creek in 2015; and 4) weekly grab samples from Lookout Creek and selected tributaries.
