Assessment of Long‐Term and Recent Trends from USGS Groundwater Level Records in Wisconsin from 1947 to 2017

Abstract

Over the past century, average temperature, precipitation, and storm intensity have increased, ultimately changing the nature of Wisconsin’s seasons, and altering the hydrologic cycle. These trends are predicted to continue over the next several decades. Several studies have investigated the role of changing climate on surface water, but there is a lack of quantitative assessment with regards to the impact on groundwater resources. This study examines long-term and recent 15-year groundwater level records in WI, and investigates potential relationships between regional groundwater trends and climate variability.
