Montana groundwater trends

These data are derived from groundwater wells in western Montana, and daily runoff data summarized for their corresponding huc8 watershed. The datasets are described in Holden et al. (in press) in the journal Scientific Reports.mt_runoff_huc8_1981-2024.csv contains daily mean huc8 runoff values extracted for each huc8 watershed in western Montana. mt_wells_topo_huc.csv contains well locations with extracted terrain covariates.The file lmer-well-prediction-recharge-lme4.rmd contains R code for fitting mixed effects models described in the study.
