Researchers with the Long Term Ecological Research station at the University of Colorado’s Mountain Research Station on the Niwot Ridge of Colorado’s Indian Peak work on the 2019 snow survey in the Green Lakes Valley, which includes the Arikaree Glacier and provides a substantial portion of Boulder, Colorado’s water supply. The LTER runs a snow survey in the valley every year.

Boulder’s winter landscape is not just a scenic wonder but also a critical factor in the region’s water supply and ecological research. Researchers from the Long-Term Ecological Research (LTER) station at the University of Colorado’s Mountain Research Station conduct annual snow surveys to monitor snowfall and its impact on Boulder’s water resources.

Located on Niwot Ridge in Colorado’s Indian Peaks, the Green Lakes Valley is home to the Arikaree Glacier and serves as a vital water source for Boulder. The LTER team studies the snowfall patterns in this valley to track long-term climate trends and their effects on the hydrology of the area. By collecting data each year, researchers can analyze how much water the region can expect from snowmelt and how these levels fluctuate over time.

The snow survey process involves measuring snow depth, density, and water content at various locations across the valley. These measurements help scientists understand how changing climate conditions influence the timing and quantity of water released into Boulder’s reservoirs and waterways. With climate change causing shifts in precipitation patterns, such research is essential in predicting and preparing for future water availability.

Beyond the scientific importance, the survey highlights the deep connection between Boulder and its surrounding environment. The city relies on these snow-fed water sources for drinking water, agriculture, and recreation. Without a consistent and sustainable supply, Boulder’s residents and natural landscapes could face significant challenges in the coming years.

Each winter, as snow blankets the mountains, the work of the LTER team becomes even more vital. Their findings contribute to a greater understanding of how Boulder’s ecosystem responds to climate shifts and help inform local water management policies. The combination of rigorous research and natural beauty showcases Boulder as a place where science and nature intersect, ensuring that future generations can continue to benefit from the region’s abundant natural resources.

This ongoing research not only supports Boulder’s water security but also serves as a model for other communities facing similar environmental concerns. As snow continues to shape the landscape, the dedication of these researchers remains crucial in preserving both the beauty and functionality of Boulder’s natural resources.
