RE: 2018 Aquatic Vegetation Survey and Treatment Options for Kalamazoo
Harbor, Saugatuck and Douglas, MI
This memorandum presents the results of the Kalamazoo Harbor aquatic vegetation
survey conducted by Kieser & Associates, LLC (K&A) on June 28, 2018. The survey
followed the protocols set forth in the Michigan Department of Environmental Quality
(MDEQ) Procedures for Aquatic Vegetation Surveys (2005). This involves visual
observations combined with rake tow surveys to identify species present, locations
observed and relative densities of each species. Relative densities are recorded as “a” (1-
2%), “b” (3-20%), “c” (21-60%) or “d” (>61%). These percentage values represent
cumulative coverage within each surveyed aquatic vegetation assessment site (AVAS).
The AVAS are selected to include the littoral zone where submergent aquatic plants are
growing. Each species observed and its relative density over the monitored AVAS is
entered into a calculation to determine percent cumulative cover (MDEQ, 2005) for each
species across the surveyed areas of the lake. Each survey location was recorded with a
handheld GPS unit. Survey data and maps of aquatic vegetation assessment sites
(AVAS) are provided in the Attachment. K&A surveyed a total of 107 aquatic
vegetation assessment sites (AVAS) during the June 28, 2018 survey.
During the survey, K&A collected data with a Lowrance Elite Ti sonar to input into
CiBiobaseTM for bathymetric mapping of Kalamazoo Harbor. The bathymetric contour
map is presented in Figure 1.

2018 Survey
The survey data are presented separately for the northwest and southeast lobes of
Kalamazoo Harbor to differentiate the two areas for management options.
Northwest Lobe:
This portion of Kalamazoo Harbor is bordered by Blue Star Highway to the south and the
Kalamazoo River outlet to the north. Seventeen species were observed in the 59 AVAS
surveyed with coontail (Ceratophyllum demersum), Eurasian watermilfoil (Myriophyllum
spicatum), Nostoc algae, duckweed (Lemna sp.) and filamentous algae being the five
most dominant at 12.2, 7.3, 5.9, 4.9, and 4.4 percent cumulative cover, respectively.
Other species observed during the survey include the aquatic and shoreline species: water
stargrass, Elodea, thinleaf pondweed, arrowhead, Phragmites, white water lily, yellow
water lily, purple loosestrife, cattail, bladderwort, arrow arum, and curly leaf pondweed.
Invasive species detected during survey include: Eurasian watermilfoil, Phragmites,
purple loosestrife and curly leaf pondweed. There was overall, very little aquatic
vegetation present in the northwest lobe of the lake. The areas where the vegetation was
surfacing and creating potential nuisance conditions were near the City of Douglas Union
Street public boat launch (AVASs 46 and 47), and in the shallow (4’ depth) area in the
east part of the lake (AVAS 107). The majority of the lake had sparse vegetation likely
due to poor water clarity. The cumulative coverage data for all species identified in the
northwest lobe during the 2018 survey are shown in Table 1.

(Heteranthera dubia) at 36.6, 22.6, 18.7, 17.0, and 15.1 percent cumulative cover,
respectively. Other species observed during this survey include the aquatic and shoreline
species: Phragmites, thinleaf pondweed, arrowhead, cattail, Nostoc, white water lily,
Elodea, floating leaf pondweed, pickerel weed, yellow water lily, naiad, purple
loosestrife, arrow arum, curly leaf pondweed, bulrush, water smartweed, and
bladderwort. Invasive species detected during this survey include: Phragmites, purple
loosestrife and curly leaf pondweed. The densest aquatic submerged aquatic vegetation
was present along the east and south shorelines. Navigation was impeded by surfacing
vegetation near AVASs 71 to 75. Dense stands of Phragmites were observed along the
shoreline adjacent to AVASs 49 through 62. The cumulative coverage data for all
species identified in the southeast lobe during the 2018 survey are shown in Table 2.

Management Options:
Options for managing aquatic vegetation vary depending on the species present, project
budgets and goals of the stakeholders. The following management options are provided
to the Cities of Saugatuck and Douglas for consideration.
Northwest Lobe:
The northwest lobe of Kalamazoo Harbor has very little submerged aquatic vegetation
with the exception of the area near the Union Street boat launch and a shallow offshore
Kieser & Associates, LLC 536 E. Mich igan Ave. , Su i t e 300 , Kalamazoo , MI 49007
page 5
area along in the east part of the Harbor. Phragmites was detected along the shoreline
near AVASs 1, 2, 3, 37, 44 and 47. Purple loosestrife was observed along the shoreline
near AVASs 1, 4 and 5.
• The vegetated area near the Union Street boat launch does not appear to be
inhibiting navigation or recreation and is therefore not recommended for
treatment at this time. Given the limited amount of submersed aquatic vegetation
in the northwest lobe, encouraging plant growth in areas where recreation will not
be impacted is recommended.
• The offshore patch of vegetation (AVAS 107) could be chemically treated with an
herbicide targeted for milfoil. Eurasian watermilfoil was observed surfacing at
this AVAS. The other species present at this site were not creating nuisance
conditions at the time of the survey. If the Cities are interested in pursuing
aquatic herbicide treatment, coordination with an aquatic herbicide applicator is
recommended. A Michigan Department of Environmental Quality (MDEQ)
Aquatic Nuisance Control (ANC) permit is required for any chemical
application to Kalamazoo Harbor.

management.

• Phragmites observed was brown and appeared to have been previously-treated.
Continued follow-up monitoring and management is recommended to help
control the spread along the shoreline.
• Purple loosestrife was fairly isolated and observed in low densities during the
survey. Hand digging of the plants to remove the roots is recommended for this
small infestation. If digging is not feasible, at minimum, the flowers should be
cut and removed prior to seed set to inhibit spread. All plant fragments should be
placed in a plastic bag, removed from the site, and sent to a landfill. Spot
treatment with a glyphosate-based herbicide is another management option.
For larger purple loosestrife infestations, the biocontrol purple loosestrife beetle,
Galerucella sp., has been shown to be an effective management tool given time
(multiple years) and a sufficient population of beetles. K&A has been rearing the
beetles for several years and could assist the Cities with a management plan if the
purple loosestrife becomes more widespread.

• Curly leaf pondweed was observed in very low densities in isolated areas during
the survey. No treatment is recommended at this time.
• K&A staff noted water clarity of less than about two feet during the June 28, 2018
survey. Light can typically penetrate two times the Secchi depth (water clarity)
which equates to the depth where plants can grow in a lake. This means that
plants will likely not grow below four feet in Kalamazoo Harbor. Measures to
address water clarity issues are recommended by K&A to increase the diversity
and abundance of native aquatic plants in the lake. Watershed loading to
Kalamazoo Harbor should be investigated to better understand the sources and
impacts on the water quality, aquatic vegetation and biota.
Southeast Lobe:
The southeast lobe of Kalamazoo Harbor has significantly more submersed and shoreline
vegetation than that observed in the northwest lobe. Navigation is impeded on the
east/southeast shoreline (AVASs 70-76) and Phragmites is dominant along the north
shore from AVASs 49-62.
• Chemical treatment of the area near AVASs 69 through 76 to create navigation
lanes is recommended to increase recreational use of that area. Broad-spectrum
contact herbicides would impact the vegetation present in this area to provide
pathways for navigation. One chemical treatment/year would likely be sufficient
to maintain access for the season. An MDEQ ANC permit is also required
here for any chemical application.
• Physical cutting and harvesting of vegetation in the area near AVASs 69 through
76 could also be used as an alternative to chemical treatment to create navigation
lanes. Harvesting would likely be needed every few weeks through the boating
season to maintain the navigation lanes for recreation.
• Phragmites was observed in healthy, dense stands along the north shore.
Management incorporating a combination of chemical treatment and physical
removal is recommended to control the spread. Continued, multi-year follow-up
monitoring and management will be required to effectively manage this species.
• Purple loosestrife was fairly isolated and observed in low densities during the
survey. Controls similar to those recommended for the Northwest Lobe are
recommended here.
• Curly leaf pondweed was observed in very low densities in isolated areas during
the survey. No treatment is recommended at this time.
Kalamazoo Harbor Flushing Rate:
The water flushing rates of each of the two lobes of the Kalamazoo Harbor were
estimated using the volume of each area and the flow at the US Geological Survey
gauging station upstream on the Kalamazoo River at New Richmond Bridge. While this
Kieser & Associates, LLC 536 E. Mich igan Ave. , Su i t e 300 , Kalamazoo , MI 49007
page 7
gauging station does not account for some small downstream tributaries entering the
Kalamazoo River, it is considered a representative estimation of flushing rates. Estimates
of flushing between April and September were considered since those would be the
typical months when chemical treatment would occur. The flushing rate will influence
what chemical treatment options may be viable. Required contact time between the
target plant and the prescribed herbicide vary, so understanding the flushing rates is
important in determining appropriate treatment strategies.
Northwest Lobe:
The average flushing rate for the northwest lobe ranged from five hours in April to over
11 hours in September. It should be noted that this flow is not uniform across the harbor.
Highest flushing rates would be assumed in the center of the channel with longer flushing
rates in the embayment areas.
Southeast Lobe:
The average flushing rate for the southeast lobe ranged from one hour in April to three
hours in September. As noted above, this flow is not uniform across the harbor. Highest
flushing rates would be assumed in the center of the channel with longer flushing rates in
the embayment areas.
Consulting assistance for advancing various treatment recommendations was beyond the
scope of these survey efforts, but can however, be provided upon request and additional
authorization.

RE: Proposal for Aquatic Vegetation Management for Kalamazoo Lake,
Saugatuck/Douglas, MI
Dear Mr. Harrier:
Per the City of Saugatuck’s request, Kieser & Associates, LLC (K&A) is providing this
proposal for professional services to assist the Cities of Saugatuck and Douglas with
ongoing aquatic vegetation management to minimize nuisance conditions in Kalamazoo
Lake located in Saugatuck and Douglas, Michigan. Our proposal contains six tasks that
we believe are important to the success of this project:
• Task 1: Stakeholder meetings to discuss aquatic vegetation management options
and the necessary steps to pursue these;
• Task 2: Assistance with: a) obtaining bids from State of Michigan-licensed
chemical applicators and, b) Michigan Department of Environmental Quality
(MDEQ) permitting;
• Task 3: Early-season aquatic vegetation survey;
• Task 4: Chemical applicator correspondence and treatment oversight;
• Task 5: Late-season aquatic vegetation survey, and
• Task 6: Reporting
The total estimated not-to-exceed cost for these proposed tasks is $8,615, not including
chemical applicator costs and MDEQ permitting fees that may be required. Each task is
discussed in more detail as follows.
TASKS:
Task 1. Stakeholder Meetings (2)
K&A staff will meet with City Council members to discuss findings and
recommendations from the K&A aquatic vegetation survey conducted on June 28, 2018.
K&A will provide details on aquatic vegetation management options and necessary steps
to proceed with management agreed upon by the city councils. An initial meeting is
expected to occur during Fall 2018 to allow adequate time to obtain the necessary permits

permits and applicator contracts in advance assures that timely management can occur to
help minimize nuisance conditions during 2019 peak recreation season. Should the cities
determine that no aquatic vegetation management is desired for 2019, K&A would not
proceed to Tasks 2 through 6. The second meeting would be scheduled at a strategic time
in 2019 to discuss proposed activities and/or vegetation survey results.
Task 2. Chemical Applicator Bids and MDEQ Permitting Assistance
K&A will assist in soliciting and reviewing competitive bids for aquatic herbicide
application services with a State of Michigan-licensed pesticide applicator. The
application will be expected to prepare an MDEQ Aquatic Nuisance Control (ANC)
permit for herbicide application for 2019. The cost of the MDEQ permit is an additional
fee that is not included in this quote for services. This fee varies depending on size of
treatment area, and typical costs range from $400 to $800 annually. It can be incorporated
in the bid costs.
Task 3. Early-Season Aquatic Vegetation Survey
K&A will conduct an early-season aquatic vegetation survey in late-May following
MDEQ aquatic vegetation assessment site (AVAS) protocol. The shoreline will be
surveyed, concurrently, to identify and map areas where invasive shoreline species are
present. These data will be communicated to the selected chemical applicator for
targeted treatment of nuisance areas. Data on aquatic vegetation species presence,
distribution, and density will be collected and analyzed using MDEQ procedures. In
addition, CiBioBase™ will be used during the early-season survey. This technology uses
sonar and digital mapping tools to efficiently create accurate, detailed, interactive maps
of collected data to provide a refined assessment of treatment options. Recorded data
will include bathymetry and plant biovolume (based on the height and area of aquatic
plants in the water column).
Task 4. Chemical Applicator Correspondence and Treatment Oversight
K&A will communicate with city councils and the contracted chemical applicator to
ensure appropriate and timely public notifications and treatment(s) are made. K&A staff
will accompany the applicator during the first treatment to ensure the appropriate areas
are being treated. Treatment would likely occur in early to mid-June to allow for optimal
conditions for the summer recreation season. Costs for chemical applicator fees and
chemicals are not included in this quote for K&A services.
Task 5. Late-Season Aquatic Vegetation Survey
K&A will conduct a late-season aquatic vegetation survey during the period of late July
to early August to assess treatment effectiveness. This survey will follow the same
procedures as in Task 3.
Task 6. Reporting
K&A will prepare a written report detailing 2019 aquatic vegetation management efforts
and recommendations to guide future management of Kalamazoo Lake.
