Protecting and restoring watersheds since 2005

Science + Community

Left Hand Watershed Center protects and restores watersheds for people and the environment using a collaborative and science-based approach.

We are a stakeholder driven, non-profit organization located in Boulder County, Colorado that values science and community. We used sound science to monitor, assess, and manage our watersheds. We use data to plan and implement on-the-ground forest and river restoration projects. We strive to build a strong stewardship ethic in our community through place-based and participatory learning.

From a global pandemic to devastating local wildfires, support for local watershed protection has never been more important.

and Left Hand Creek’s Legacy of Mining

Following the discovery of gold in Denver in 1859, it did not take long for miners to work their way up the creeks into the mountains, panning for gold and searching for the veins from which the nuggets came.

Standing rather proudly in the shadow of the Rocky Mountains along the front range of Northern Colorado is a very unique little mountain affectionately known as Haystack Mountain, earning its name by the early dairy farmers who settled on its flanks.
