State engineers assess Barker Dam condition and recommend monitoring before costly repairs

The Boulder City Water Resources Advisory Board meeting on June 18, 2025, focused on the ongoing assessment and potential upgrades to the Barker Dam. Key discussions centered around the structural integrity of the dam and the implications of new state engineering requirements.

During the meeting, experts highlighted the need for a thorough evaluation of the dam's anchors, which were installed in the 1980s. These anchors, large rods drilled into the dam and its rock foundation, are crucial for the dam's stability. Due to the age of the installation, there is uncertainty regarding their current condition. To address this, test anchors have been placed outside the dam to assess the metal's integrity.

Additionally, the board discussed the importance of hydrologic monitoring. This involves drilling small holes in the dam to measure water levels and understand how fluctuations might affect stability. The experts emphasized that while a significant capital project could cost around $100 million, it is prudent to first monitor the dam's conditions before committing to such an extensive undertaking.

The meeting also touched on evolving scientific methods for assessing seismic stability. The state engineer's updated data suggests changes in how earthquake risks are calculated, prompting the board to consider how these new insights might influence the dam's safety protocols.

In conclusion, the advisory board is prioritizing careful monitoring and assessment of the Barker Dam before proceeding with any major projects, ensuring that decisions are based on the latest scientific data and engineering practices.
