Gilcrest/LaSalle Pilot Project Hydrogeologic Characterization,

Landowners and municipalities in the Gilcrest/LaSalle area have reported high groundwater conditions and resulting property damage. In response, the Colorado Water Conservation Board (CWCB) funded the Division of Water Resources (DWR) to conduct an independent pilot study to identify relationships between the climate, geology, hydrology, and water management practices and groundwater levels in the area. As part of the study the Colorado Geological Survey (CGS) completed a detailed assessment of the pilot study area geology and historic water level conditions. The CGS acquired existing groundwater level data, identified groundwater level data gaps, compiled geologic and aquifer property data, and characterized the alluvial aquifer hydrogeology. New findings include refined alluvial aquifer and bedrock surface mapping and revised surface geologic mapping. Additionally, the CGS refined the aquifer lithologic and depositional conceptual model, providing insights into near-surface layers impeding downward groundwater flow. The outcome presents a holistic, three-dimensional view of the aquifer providing a sound conceptual model foundation as the pilot study moves forward.
Andy Horn develops, designs, and implements scientifically valid and legally defensible water resource and environmental investigations for private, industrial, and governmental clients.
