Protecting and restoring
Left Hand Creek since 2005

Lefthand Watershed Oversight Group 

Since 2005, Lefthand Watershed Oversight Group (LWOG) has encouraged the community to protect and restore Lefthand Creek Watershed for generations to come.

As a stakeholder driven, non-profit organization located in Boulder County, Colorado, LWOG 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.

Adaptive Management Guide

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.

Left Hand Stewards Work Days

Tuesday mornings are dedicated to creek stewardship along Left Hand Creek. Join us as we water native plants and remove invasive plants from our project sites. This will help native plants take back their natural habitat!

Volunteer Event

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. 

Stream Stewardship & Recovery Handbook

LWOG lead the development of a Regional Stream Stewardship & Recovery Handbook designed to provide support for landowners who are implementing stewardship practices on their creek-side properties. Email Meg Parker to reserve a copy of the Handbook.

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.
