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.

We are building a community-wide stewardship ethic rooted in watershed science through place-based and participatory learning.
We are leading a diverse partnership to address post-fire recovery and restoration, as well as landscape-scale forest health planning.
Lefthand Watershed in History
Colorado’s First Inter-basin Water Transfer and the Coffin versus Left Hand Ditch Water Case
How did an 1879 water conflict in the Left Hand Creek headwaters come to influence water law in nine western states?
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.
is it a Volcano?
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.
