Is snowpack enhancement safe?

One of the most common questions about snowpack enhancement is safety.

The amount of silver iodide used is extremely small and is dispersed over a very large area. Scientific studies have found resulting concentrations are well below naturally occurring levels found in many soils and water sources.

Does snowpack enhancement really make a difference?

Studies show snowpack enhancement can increase snowfall from individual storms by about 5 to 10%.

That may sound modest, but across an entire watershed and an entire winter, those additional inches translate into meaningful water for communities, agriculture, and the environment.

How does snowpack enhancement work?

Snowpack enhancement uses tiny amounts of silver iodide released from ground-based generators during the right storm conditions.

The particles help water droplets form ice crystals, which can increase snowfall naturally within existing storms.

Can we help make more snow?

❄️ It sounds surprising, but snowpack enhancement has been used across the western United States for decades to increase snowfall during winter storms.

In 2022, the St. Vrain and Left Hand Water Conservancy District launched the Front Range's first snowpack enhancement program to help strengthen long-term water supplies.

Mission Accomplished! 250 fish returned to St. Vrain Creek 🐟

When irrigation season ends and diversion structures shut down, fish can get stranded in standing pools below ditch headgates with nowhere to go as the water disappears.

This fall, the District and Highland Ditch Company collaborated to change that. In August, our teams worked quickly to rescue fish trapped in the Highland Ditch and return them to the creek. We salvaged a variety of native and sport fish species, giving over 250 fish a second chance.

A huge thank you to Highland Ditch Company for their partnership on this. We're also grateful to Colorado Parks and Wildlife staff for their expertise and thoughtful collaboration throughout the process.

Colorado farmers constantly adjust to changing water conditions.

They coordinate with ditch companies, work with neighboring producers, and make difficult decisions about which crops and fields receive limited water.

Their resilience helps keep food on our tables, even during challenging years. Thank you to our Colorado ag industry!

Less water doesn't just mean less irrigation.

Many irrigation ditches are unlined, which means water naturally seeps into the ground as it travels. During drought, lower flows make it even harder to deliver enough water to farms at the end of the system.

Every drop matters. Share with someone interested in Colorado water.

Did you know Colorado water is distributed by water rights?

During drought, farms with more senior water rights generally receive water first. Those with more junior rights may receive less, or none at all.

Understanding how water is allocated helps explain why drought impacts every farm differently.
