Barnes Lake Management District

The Tumwater City Council created the Barnes Lake Management District (BLMD) by ordinance on December 7, 2004, following the approval of a citizen petition of lake property owners to the Tumwater City Council to help improve aquatic conditions around the lake. On August 2, 2005, the Tumwater City Council appointed a steering committee, which serves to advise the Council on planning, project implementation, and the allocation of assessed funds.

The Steering Committee represents the interests of ALL property owners and residents within the BLMD. The selected citizens represent varied interests, are spatially distributed around the lake and all share a common concern for the health of Barnes Lake.

Some of the current issues and opportunities the Steering Committee addresses include management of aquatic plants, noxious weed prevention and eradication and vegetative debris removal; environmental education; and wetland habitat management and preservation.


Please contact your neighborhood representative for most current meeting information and lake updates, or sign up for the City of Tumwater's Barnes Lake District email list.

For immediate assistance, email Dan Smith, Water Resources Program Manager, or call (360) 754-4140.

NEW FOR 2020!  Private Lake Treatments

2020 Private Property Lake Treatment ApplicationPDF file

The Barnes LMD Steering Committee recently approved a process where private property owners around the lake can hire the City's consultant, Northwest Aquatic Eco-Systems, to conduct aquatic vegetation treatments.

This application is intended for use by members of the Barnes Lake Management District (BLMD) to request treatment of aquatic vegetation on private property utilizing the City of Tumwater’s Aquatic Plant and Algae Management Permit.

 ** Please note, depending on the scope of work, additional permits may be required from local, state or federal agencies.  This application is for the management and removal of aquatic vegetation up to and including the high water mark. **

What does this application cover?

This application covers the management, treatment, and removal of any aquatic vegetation species covered by the Aquatic Plant and Algae Management General Permit.  However, only treatments approved by the City for use in Barnes Lake are authorized.  The City authorizes use of treatment materials that have been approved for use in Thurston County. The list of approved treatment materials is found here:

Who is eligible to apply?

Any active member in good standing (no BLMD assessments outstanding) is eligible to seek coverage under the City’s Aquatic Plant and Algae Management General Permit.  Treatments may only be applied water ward of the ordinary high water mark.

How much does it cost?

There is currently no cost to apply; however, all costs pertaining to the treatment defined by the scope of work with Northwest Aquatic Eco-Systems are the responsibility of the property owner.  Neither the City, nor the BLMD, will be liable for work completed on behalf of a private property owner.

Who is responsible for the work?

The property owner and Northwest Aquatic Eco-Systems are the responsible parties to apply for the project, complete the work and pay for all costs associated with the scope of work.  The City is not financially or legally responsible for the project.
