Long Lake has been suffering for years with significant water quality issues that have promoted the growth of invasive aquatic plants and toxic algae blooms. These issues come from past land use practices on shoreline and upland lots, surrounding soil conditions and natural lake processes. These issues have impacted use of the lake for recreation and created frequent public health hazards. These issues have been addressed in the past through state-funded management activities to reduce the accessibility of phosphorous and other nutrients within Long Lake.
To fund current management activities, private funding was necessary. To this end, the community and Kitsap County proposed a lake management district for properties surrounding Long Lake. Through annual assessments of $450, properties within the proposed District boundary fund specific lake management activities established by an Integrated/Adaptive Lake Management Plan. More information regarding maintenance activities, district boundary and assessments can be found in the documents linked under project documents.

Aquatic weed control activities will begin soon in Long Lake. Kitsap County has contracted with AquaTechnex, LLC, a company out of Centralia, to treat the pond weed (Potamogeton spp.) that unexpectedly took over large parts of the shoreline last spring and summer. The hatched areas on the map below will be targeted. Lakefront property owners were mailed a notice on April 30 with further details.
AquaTechnex will be applying fluridone pesticide to the pondweed three times, starting in mid to late May. If necessary, a fourth treatment using Diquat will be applied after the fluridone treatments. Notices will be posted along the waterfront, at the boat launch and at Long Lake Park 24-48 hours before each treatment.

Summer 2019 Lake Management Update
Following an alum treatment in April, nutrients in the lake have been significantly reduced greatly improving lake clarity. This should have a substantial effect of any algae blooms in the future removing last year's public health hazard.
However, this lake clarity and remaining nutrients from upland land uses and soils in the lake bottom have led to additional vegetation growth in the lake. A plant survey was conducted on July 1st to document the breadth of this growth. Two new native plant species (sago pondweed and slender-leaved pondweed) have established themselves in the lake. Although native, the densities exceed those that would be found in a healthy lake. Plans are underway to combat this growth through a fall vegetation treatment.
Citizen volunteers have continued lake monitoring on a monthly basis. They are measuring transparency, phosphorus concentrations and chlorophyll. The monitoring, plus plant surveys and observations of conditions will help the scientific team adjust treatment based on what they are finding.
There will be a meeting on July 30, 2019 at 6:00 PM at the Long Lake Community Center to update residents about the efforts of the Lake Management District and to discuss next steps. Click here to see more details in the "Long Lake Mid-summer Update 2019" or the document is in the project documents column.

As part of our ongoing lake management activities, the
Management District has planned an extensive alum treatment to be applied this
month. Lakefront property owners will be receiving a Business and Residential
Notice in the mail this week for this treatment beginning the week of April 22,
Consultants will be using a modified boat with spray nozzles
to apply alum over the entire surface of the lake. They will be using the Long
Lake boat ramp as their staging area, but thiswill not affect the public’s use
of the ramp.
As part of the Washington Department of Ecology’s permitting
requirements, the management district must also install temporary signs at
least every hundred feet along the shoreline, no more than 48 hours before the
treatment begins. Lakefront owners may notice people placing these 8 ½ x
11-inch signs along your shorelines or docks. We will make this as unobtrusive
as possible while still meeting the state notice requirement.
We apologize for any inconvenience and if you have any
questions, please contact Jennifer Haro or Eric Baker at (360) 337-7080.

Lakefront property owners should receive a notice the week of March 11 regarding upcoming alum treatment of Long Lake. The treatment will take place in late April or early May. Another notice will go out later this Spring when the specific date range is known. The alum will limit nutrients (phosphorus) in the lake, reducing invasive vegetation growth and limiting the potential for toxic algae blooms.
Some logistics for the treatment: Our contractor will be applying alum to the lake using a modified pontoon boat with a tank and spray nozzles. They will be using the boat launch as a staging area, so visitors to the launch may notice storage tanks for the alum and a thick hose out to the end of the dock. There will also be several tanker trucks delivering the alum to the site during the treatment. However, the boat launch will remain open to the public during the treatment window.

The following is a brief outline of Long Lake management activities for the spring through fall of 2018.
Aquatic plant management activities restarted with the late growth season treatment of 25% of the shallow littoral area targeting the invasive non-native (AIS-aquatic invasive species) white lily, Brazilian elodea, and Eurasian water milfoil. Also, included in this treatment was excessively dense beds of native pond weed that also include some AIS targeted above. Every year going forward 15-25% of the lake shallow littoral area will be treated based on a rotational 4-year coverage adaptive program to ensure the re-establishment of native plant communities for aquatic ecosystem recovery, while maximizing the direct beneficial uses of the lake. In the late spring of 2019 the treatment effectiveness will be assessed and new as well as re-treatment areas will be identified for a summer control.
This was an interesting year for lake water quality. The volunteer monitoring team have monitored the lake starting in May through September. The last data set is not yet available from the laboratory. However, here is what the data from May through August informed us about the lake:
To limit the phosphorus and thereby limit the phytoplankton potential for an algal bloom production a phosphorus inactivation and water column stripping treatment is planned for the late spring of 2019. This will help limit the potential for a algal bloom and improve overall lake water quality.

Specifically, aquatic plant treatment will be conducted as described below:

After tabulation of the ballots submitted by property owners through February 10 2017, the proposal to form Long Lake Management District No. 3 has passed with a 55.5% yes vote (simple majority was required).
With Board of Commissioner approval of the District on June 12, 2017 and the assessment roll on August 14, 2017, Kitsap County has put the maintenance activities out to competitive bid. Through a request for proposal process, members of Kitsap County Stormwater, Kitsap Public Health, the Noxious Weed Board and Commissioners Office, will review submittals and select a consultant to begin lake activities in the near future.
To ensure good coordination between the residents within the District and the contractor, Kitsap will be forming an advisory committee made up of local residents, the departments listed above and the contractor. This will allow a quarterly assessment of any issues that may arise during the maintenance activities. If you reside within the district and have interest in serving on such a committee, please contact Eric Baker, Policy Manager, at the information below.
If you have any questions regarding the proposal, the ballot tabulation or next steps. Please contact Eric Baker at (360) 337-4495 or email@example.com.
The consultants that
are treating the lake with alum have created a website with more details about
the treatment. It can be viewed at
