October 3, 2017 Lakeland Elementary School Chris Knutson King County Water and Land Resources Division
Lake Management Plan Action items
Activities undertaken, planned and changed
Budget Timeline Questions
Goal 1: Maintain Lake Outlet
King County- clear obstructing sediment and vegetation
at culvert
Removing vegetation along channel may not be helpful
Contact KC when channel just starts to flow
survey for obstructions return during a storm for high flow obstructions
Permit requirements for debris in channel
Manmade objects/debris vs large wood
Goal 2: Preserve Current Lake Water Quality
Participate in Lake Stewardship Program
Thanks to the Gallands, time to pass the torch to
new volunteer monitor
Presentations by experts at public meetings Email existing educational materials to residents
Will also be posting materials on new website: http://www.kingcounty.gov/services/environment/wa
ter-and-land/lakes/lakes-of-king-county/lake- geneva/lmd-advisory-board.aspx
Goal 3: Preserve Public Health Status
Prevent toxic algae blooms
Educate residents on nutrient reduction techniques
Distribute and post educational materials
Have experts attend public meetings
Manage Canada Geese
Educate residents on barrier installation and yard deterrent methods
Contract with USDA to implement scare tactics and lethal methods as necessary
Still developing a comprehensive plan for geese control
Goal 4: Prevent Future Invasive Aquatic Plant
Infestations
Annual Survey of Aquatic Plants once per year
(completed Aug 2017)
Educate public to identify invasive species and prevent
the spread
Email residents and post to website Have expert attend public meetings
Abundant native plants
nymph (on permit)
Noxious/invasive plants
water lily (on permit)
(on permit)
loosestrife (on permit)
(not on permit)
cattail (not on permit)
Goal 5: Manage Current Invasive Aquatic Plant Infestations (and Debris)
Purple loosestrife and yellow flag iris- starting herbicide in 2018 (years 2,4,6,9)
Narrow leaf cattail- herbicide 0.1 acres per year starting in 2018(years 2,4,6,9)
Will be added to permit Do we delay treatment to attempt to get grant?
Fragrant water lily- eradication through herbicide starting 2018, 2 treatments per year (then 2,4,6,9 or as needed)
Curly leaf pondweed will be added to permit and depending on costs may be treated along with native najas/pusillus
Manage dense stands of native pondweeds in high use areas-
Add small pondweed to permit volunteers use weed rakes to reduce plant populations Herbicide 0.35 acres per year (2,4,6,9) Maybe larger area depending on costs
littoral zone can be treated annually
pondweed may be treated as well (cost dependent)
treated in 2018
Goal 6: Manage Aquatic Debris
Removal of one large Lily mat by contractor (approx.
9,000sq ft)
Still working on appropriate method for removal Cut up? Barge and excavator? Water jet?
“cookie cutter”?
May exceed budgeted cost depending on permits
and method of removal
$6325 Grant opportunity? Grants typically have 25% match
Goal 7: Educate and Involve the Lake Geneva Community
Annual public meetings Expert presentation during public meetings Distribute educational material to residents Email and website
