The future of Virginia City’s water

Virginia City is in the process of the required review and update to its existing Source Water Protection Plan (SWPP). An SWPP investigates the quantity and quality of municipal water supplies, and helps guide management and planning efforts for a municipality to ensure adequate, potable water for its residents and visitors.

As the Western writer Wallace Stegner once noted, “aridity makes the various Wests one.” Given the current severe drought and concerns regarding climate in the coming decades, it’s important to note that Virginia City is perhaps more sensitive than most other municipalities given the underlying geology of these rocky hills, our significant uptick in seasonal visitation and increased water demand, and the potential for land development in areas that we depend upon for water. Currently, the entirety of the town’s water supply originates from two springs northeast of town.

Virginia City rely on the Montana Bureau of Mines and Geology (MBMG) to provide the science necessary to make informed water management decisions for our town. Initial efforts of data collection began in 1970, but the first SWPP wasn’t finalized until 2000. Following years of public input  and review, an updated document was finalized in 2016. Notably, a major MBMG investigation of our town’s water supply using a number of modern-day methods (LiDAR, Electrical Resistivity Tomography Surveys, VLF Electromagnetic and Seismic Surveys) is nearing completion.

Preliminary results indicate a few important land development and planning considerations:

• Spring 1 provides the vast majority of the town’s water and meets the current water demand for the Town of VC

• Spring source areas (Lower graghic) are highly sensitive to surface activity, wells and/or septic systems given the local geology near springs (Above graphic)

• Alder Gulch represents the next best opportunities for water development but would be expensive and have risks associated with historic mining practices and water rights

• Additional wells in the area indicate significant arsenic concerns

These investigations clarify that the town’s best option is to preserve the integrity of the spring source areas. All other options include significant caveats and uncertainty of water quantity and quality.

Thanks for reading and considering the current state of this old mining town’s water prospects. As always, anyone selling or purchasing land or property should conduct due diligence and become informed about potential regulations or considerations regarding land development. Please stay tuned for a public presentation of the MBMG study in the coming months and visit the Virginia City website for more information.
