Effects of groundwater fluctuations on the distribution and population structure of two cyprinid fishes in a desert spring complex

The data in this dataset are Excel files containing multiple spreadsheets of raw data collected during a study on relationships between groundwater levels, surface water levels, and the distribution and population structure of Least Chub (Iotichthys phlegethontis) and Utah Chub (Gila atraria) in a spring complex in Snake Valley in the eastern Great Basin (Utah, USA). The files include UTM coordinates and measurements of water and sediment depths obtained during a 2013 bathymetric survey of the spring complex (BathymetryPointDepths.xlsx), daily averages of groundwater levels from a nearby monitoring well during 2012-2014 (GroundwaterSG25D_2012-2014.xlsx), monthly averages of groundwater levels during 2009-2017 (GroundwaterSG25D_Monthly.xlsx), daily averages of groundwater levels at four nearby monitoring wells on dates when surface water monitoring surveys were also conducted (LelandWellsGWL_WaterMonitoringDays.xlsx), corresponding data on precipitation and evapotranspiration rates from a weather station near the spring complex (PartounClimateData.xlsx), measurements of surface water depths at monitoring points within the spring complex (SurfaceWaterMonitoringData.xlsx), visual survey data pertaining to monthly changes in the distribution of juvenile and adult Least Chub and Utah Chub with changing water depths (VisualSurvey_AdJuv_WaterDepth.xlsx), and data from passive sampling of fish populations, including water depths of minnow traps and total length measurements of fish captured. A short narrated video explaining the major findings of the study is also included with the dataset.
