6. OLD BUSINESS
6.1 Illicit Discharge follow up: Action: Sue Polka will try to find some appropriate stencils/marking systems
for the storm drains.
6.2. Removal of Silt around storm drain exits: Discussion/Planning: (Gary Gerding, Sue Polka) Reference:
Minutes of last meeting, October 9, 2018. We agreed that the lake should first be protected from additional silt
by grit chambers before trying to remove existing silt.
6.2.1 Next steps towards removing accumulated silt from Karth Lake: Action Requested: (Sue Polka,
Shawn Tracy) Using the diagram below presented by Shawn in our last meeting, and considering the
watershed area and node numbers drawn in by Gary, identify: 1. Which inlets are connected to which
outflows and draw in connections; 2. Where additional grit chambers should be installed before we
consider removing silt from the lake. Are there any plans to add these grit chambers? What events/road
conditions/etc. would trigger the installation of these grit chambers?
6.3 Art Larsen Memorial Garden update: Discussion/Planning: Maintenance and/or improvement plans?
Action Requested: Kathy: Sources of labor for mulching and edging? Sue: What is the length of the garden
perimeter? Does the city have brick supplies for edging? How much?
7. NEW BUSINESS
7.1 Results of 2018 CAMP monitoring of Karth Lake (Gary will report summary data if it is completed in
time by the Met Council and RCWD).
7.2 Street Cleaning Concerns: Susan Johnson will report her observations and recommendations.
7.3 Removal of Excess Weeds and Debris from Karth Lake in 2019. (Discussion/Planning led by Gary) Gary
plans to arrange for weed removal, etc. again this year if there are neighbors that want it done. Gary invites
suggestions regarding the process.

7.4. Explore: Use of Fountains/Aerator to improve lake water quality. Gary invites comments and
information on the installation of these devices to improve Karth Lake water quality. They will cool and
oxygenate the water and burn off some nutrients. Does Sue or Shawn have any information on their benefits,
or installation and maintenance costs? Is a permit required? Do we need approvals from all/some of the
residents on the lake?
7.5 Information: Seven Metro area cities filed separate lawsuits last year in U.S. District Court against a
group of seven companies that refine coal-tar sealants. They're asking for help to pay for cleaning up and
removing contaminated material from their stormwater ponds. (Gary will share information that may apply to
us if and when we remove silt from Karth Lake.) Related link:
