Hydraulic conductivity estimates for near-surface alluvium, derived from slug tests in 27 monitoring wells surrounding the Cattlemans detention basin in South Lake Tahoe, California. The data was collected to assess groundwater flow and subsurface nutrient transport as part of a five-year study on the basin's effectiveness in reducing urban runoff pollutants. Summary information was provided by the USGS.
Use Cases
- Model subsurface nutrient transport rates using the estimated hydraulic conductivity values ranging from 0.5 to 70 feet per day.
- Analyze spatial variability of aquifer properties by comparing conductivity results from the 27 distinct monitoring well locations.
- Assess measurement reliability by examining the test repetition data, where 24 wells were tested multiple times with results typically within 10 percent of the average.
- Calibrate groundwater flow models for the Cold Creek and Trout Creek watersheds using the site-specific conductivity average of 17.8 feet per day.
Strengths
- Data includes repeated slug tests at 24 out of 27 monitoring wells, allowing for reliability assessment.
- Provides a concrete range (0.5 to 70 ft/day) and average (17.8 ft/day) for hydraulic conductivity in the study area.
Limitations
- The exact sample size (number of individual test records) is not specified, only the number of wells (27).
- Data is geographically limited to the immediate vicinity of a single detention basin in South Lake Tahoe.
