Davids Engineering was subcontracted under Larry Walker Associates in an effort for the Shasta Valley Resource Conservation District, funded by DWR, to collect additional data to better understand hydrological and hydrogeological processes in the Shasta Valley and support groundwater resource management under the Sustainable Groundwater Management Act. This includes the installation and monitoring of piezometer transects at select locations along surface water features in the Shasta Valley to evaluate surface water-groundwater interactions.
Monitoring shallow groundwater elevations adjacent to surface water features can help identify the direction and gradient of groundwater flow near the stream-aquifer boundary. Davids Engineering led the study design (including transect location recommendations; equipment specifications and setup; and development of data management protocols), equipment installations and site commissioning, and initiation of data collection. This study is currently ongoing and recording continuous water surface elevation and temperature data with Davids Engineering supporting the SVRCD to maintain the piezometers and equipment.
Once the study concludes, Davids Engineering will lead development of a technical report summarizing the study findings. It is anticipated that the study will provide insight into stream-aquifer interactions that will be valuable to local stakeholders and water managers and support sustainable groundwater management in the Shasta Valley.
