Protecting and restoring watershed health since 2005
Left Hand Watershed Center
Left Hand Watershed Center protects and restores watersheds for people and the environment using a science-based approach.
As a stakeholder driven, non-profit organization located in Boulder County, Colorado, the Watershed Center serves the community by monitoring and protecting water quality and important water sources for over 20,000 residential and agricultural water users, implementing restoration projects, and striving to build a strong stewardship ethic within the community.

This guide introduces the concept of adaptive management and describes how Lefthand Watershed Oversight Group developed an adaptive management plan for watershed resilience in Left Hand Creek Watershed.
Read about our new research project! We are working with CU Boulder researchers to study the ecological benefits of a stage zero restoration project. Our management actions to improve watershed health today must continue to benefit the future. Thank you to all our partners!
Lefthand Watershed Oversight Group would like to thank Garney Construction and Left Hand Water District for helping us restore the banks of Left Hand Creek. The crew planted 1,000 trees on our 41st Street project site which will help stabilize the banks of Left Hand Creek and reduce sediment runoff downstream.
September 12, 2018 marks five years since the beginning of the floods. This multi-day storm resulted in 17 cumulative inches of rain in Jamestown, CO and a state of emergency throughout Boulder County. Left Hand Water District Manager, Chris Smith, and our Executive Director, Jessie Olson, share a common vision for Left Hand Creek: to move forward in a positive direction and ensure restoration and resilience in the watershed!
Our newest project involves stream restoration in Left Hand Canyon. This project includes nine sub-areas (indicated on the map linked below) and work will start soon! Check back for the Request for Proposal to be posted later this spring.

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.
