Preliminary 2012 Annual Aquatic Invasive Species Report
September 2012
Voluntary Watercraft Inspections Program
Trained inspectors will be employed to help educate watercraft users about AIS and inspect watercraft
at city -owned public water accesses. Inspection hours will be distributed over peak use times.
During a 20 -week period in 2012, approximately 2,740 education and inspection hours will primarily be
funded with contributions totaling $48,971 received from four sources:
Riley Purgatory Bluff Creek Watershed District $25,000
City of Chanhassen 10,000
MN Department of Natural Resources 7,750
Lotus Lake Conservation Alliance 6,221
Sub -Total $48,971
City Administration $13,700
Total 2012 Program $62,671
The city contracted with Volt Workforce Solutions to provide aquatic invasive species (AIS) education and
voluntary watercraft inspections at a rate of $15.75 per hour. The cost of AIS policy review, program
administration, and administrative support services is estimated at $5.00 per inspection hour, for a total
of $13,700.
Of the $48,971 specifically programmed for this project, $41,816 was used for education and voluntary
inspection employment hours and $7,155 was invested in Volt Workforce Solution employee supervision,
training, uniforms, materials and equipment.
This education and voluntary inspection program took place at three city -owned public water access
points —Lake Ann, Lake Susan and Lotus Lake —at peak use times, generally from 6 a.m. to 10 a.m. and
again from 4 p.m. to 8 or 9 p.m., Monday thru Thursday; and from 6 a.m. to 8 p.m. on Friday, Saturday
and Sunday.
Through September 3, 2012, 2,761 watercraft inspections have been tallied at the three public water
access sites.
Lotus Lake
2,010
Lake Susan

Lake Ann*

*Lake Ann is a non - motorized water body.

The average per hour inspection rate for the three locations during the time period May 12 to
August 10, 2012 is:
Lotus Lake
1.64 watercraft per hour
Lake Susan
0.57 watercraft per hour
Lake Ann
0.48 watercraft per hour
Of the 2,761 inspections recorded between May 12 and September 3, 2012, a total of 2,663 watercraft
(96.5 %) arrived at the public access in compliance with state laws pertaining to aquatic invasive species. A
total of 98 watercraft (3.5%) were noted as having a violation upon arrival at the access. The violations
noted at arrival include:
Aquatic plants on watercraft /trailer 49
Bilge Plug in place 45
Water on -board or in motor 4
Upon exit from a public water access ramp, aquatic plants were cleaned from 64 watercraft /trailers and
water was noted as still remaining on board in 2 watercraft.
In addition to dozens of Volt Workforce Solutions employees, all Carver County Sheriff's deputies have
been trained in AIS enforcement.
Best Management Practices for Water Access
Minnesota Department of Natural Resource's "Best Management Practices for Water Accesses" will be
implemented at city -owned public water accesses.
On February 27, 2012, staff reviewed proposed action steps for a 2012 Aquatic Invasive Species Program,
including proposed best management practices (BMP) for city -owned boat access sites with the City
Council. The goal is to educate the public about the presence of aquatic invasive species (AIS) in our
environment and how best to avoid spreading these species.
Existing BMPs were inventoried and proposed BMPs were evaluated for both entering and exiting
watercraft. The Minnesota Department of Natural Resources delivered a variety of AIS education signage
to the city for installation at public water locations. Signage kiosks were manufactured and installed at all
three city -owned public water access locations and a "clean in /clean out" street stencil was purchased to
facilitate painting this message on the in -bound and out -bound approaches to each access. In total,
$4,900 was invested in materials and supplies for Best Management Practices for water access
improvements. The largest portion of the 2012 BMP proposal, $11,400 for additional asphalt, was not
completed to minimize additional hard surface areas at the landings. The city will continue to procure and
install AIS educational signs as they become available and implement any new BMPs that are identified
and approved.
Grants and Collaborate with Other Project Partners
City Council and staff have worked with numerous agencies and organizations in an effort to protect area
lakes from infestation by aquatic invasive species. Discussions between the Minnehaha Creek Watershed
Districts and officials from area municipalities were initiated on March 10, 2011. Subsequent to this
meeting, additional organizations became involved in seeking a solution including the MN Department of
Natural Resources, Carver County Parks, Riley- Purgatory -Bluff Creek Watershed District (RPBCWD) and
lakeshore associations and homeowners from Minnewashta, Christmas and Lotus Lake.
As a result of this collaboration, the City of Chanhassen, RPBCWD, and the Lotus Lake Clean Water Alliance
participated in a program to inspect watercraft entering and exiting Chanhassen area lakes with a city -
owned access point. In addition, the Department of Natural Resources offered training for inspections
and funds to help defray the costs of the inspection program. The cost of the program was divided
between the participants as follows:
• Riley- Purgatory-Bluff Creek Watershed District $25,000
• City of Chanhassen $10,000
• MN Dept. of Natural Resources $7,500
• Lotus Lake Conservation Alliance $6,221
The City of Chanhassen administered the program and performed all database management and reporting
and other tasks necessary to comply with grant requirements. The city also was responsible for
installation and maintenance of signage.
The Minnehaha Creek Watershed District collaborated with the Christmas Lake Association, the Lake
Minnewashta Association and Carver County Parks to administer similar programs on Christmas Lake and
Lake Minnewashta. The city was not involved beyond planning level because of the unique character of
these lakes. The boat launch for Lake Minnewashta is owned by Carver County Parks and the Christmas
Lake boat launch is in Shorewood.
Public Awareness and Education on AIS
The City of Chanhassen sponsored a public meeting on aquatic invasive species at the Chanhassen
Recreation Center on October 29, 2011. This meeting is available on -line on the City's website, as are
numerous links to other educational resources concerning aquatic invasive species, as well as general lake
management information. Staff from the MN Department of Natural Resources, the Lotus Lake Clean
Water Alliance, the Christmas Lake Association as well as staff members from the City of Chanhassen and
other concerned community members provided input at this meeting.
During the 2011 boating season, the city received signs from the Minnesota Department of Natural
Resources that were placed at the Lotus Lake boat launch. In 2012, additional signage was added at Lake
Susan and Lake Ann. Other methods to disseminate information included literature and pamphlets
available at city offices and collaborating with Minnehaha Creek Watershed District and Carver County
Environment and Natural Resources on drafting articles for the Connection, the Villager and other
publications.
