Donnells Dam

ClientTri-Dam Project
LocationTuolumne County, CA
DisciplinesLand Surveying

This project required comprehensive as-built documentation of Donnells Dam in Tuolumne County, including the upstream and downstream faces, thrust block, outfall and spillway gate structures. The firm’s completed work product would be used to further analyze the existing condition of the dam and associated structures and to meet the requirements of the Federal Energy Regulatory Commission. O’Dell Engineering utilized a combination of advanced measurement instruments, foremost among these was the Leica Geosystems ScanStation C10 3D Laser Scanner. Additionally, control and monitoring surveys were completed using one of the firm’s five fully robotic total station surveying instruments. In only three days’ time, the entirety of Donnells Dam was completely measured in the field. Over the next several weeks, the O’Dell Engineering team began producing high quality deliverables in the office. The final result was comprehensive as-built documentation of the dam, on time and on budget.
