Re: Lake Lucy Oxygen Levels
Dear Resident:
The City of Chanhassen routinely checks the winter oxygen levels in Lake Susan
(see enclosed February 7,2008 Chanhassen Villager article). The oxygen levels
in Lake Susan currently range from 2.1 mg/l at 12-foot depths to 3.8 mg/l near the
surface. These levels are beginning to enter a range where fish populations will
experience stress. Oxygen levels below 2 mg/l throughout the water column can
be lethal, depending on the species of fish present.
On February 4, 2008 a member of our staff visited Lake Lucy to take an oxygen
reading. Oxygen levels in Lake Lucy currently range from 1.57 mg/l at 14-foot
depths to 4.1 mg/l near the surface. As a comparison we also took a reading on
Lake Ann the following day and found oxygen levels from 10.1 mg/l to 14.1 mg/I.
Many factors enter into the equation that determine if a lake will experience
winterkill. The current oxygen levels in Lake Lucy are low; however, this fact
alone is not an absolute predictor that the lake will experience either a partial or
complete winterkill.
Weather conditions including snow depths, duration of sunlight and te:gIperature
all playa role, as does the photosynthesis capacity of plants in the lake. .
Respiration ofba~teria present in the lake that break down organic ,matter
significantly lowers the level of available oxygen., The infusion ofgr()Ui)dwater,
especially in shallow lakes, Can help to raise oxygen levels. In the evenHhat Lake
Lucy does experience some level of winterkill, all is pot lost. ,Acomplete,', "
winterkill would rid the lake of carp, bullhead and other undesirable fi.sh spedes;, ' ,
In addition, any level of winterkill alters thepredator/prey relationship and can. '

The City of Chanhassen · A growing community with clean lakes, quality schools, a channing downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.
Maintaining
the fishery
Snow and ice cover on the
lake blocks sunlight from pen-
etrating to the water, which in
turn limits oxygen production
through photosynthesis, and
the lake's oxygen levels drop,
creating a stressful situation
for many species of fish.
This leads to problems in
shallovv, weedy lakes, which
are more susceptible to win-
terkill than are deep-water
lakes.
Chanhassen's Lake Su-
san was often susceptible to
this until the city obtained
a water aerator through a
grant that was approved from
the fisheries section of the
Minnesota Department of
Natural Resources in 1993.
Up until that time, records for
the past 20 years indicate that
winter-kill occurred about
every other year.
The aerator works through
a pump that's put into the wa-
ter through a three-foot hole in
the ice. It's attached to floats,
which support it when the
ice eventually melts from the
churning water underneath
it. The pump draws lake wa-
ter out and sends it through
a tube up to the shore where
the water enters an artificial
cascade (bame). As the water
cascades down the ladder of
bames, oxygen is mixed with
it. Then, a plate at the base of the
baftledirects the water out onto
the ice, where it re-enters the
lake through holes. Eventually,
the churning water will create
a large area of open water. The
oxygenated water then spreads
through the lake, creating a ret
uge area that creates a healthy
environment for fish.
Chanhassen city employee
Dean Schmieg is in charge of
inspecting the lake aeration
system. In addition to inspecting
the unit daily to ensure that it's
running, he'll use an oxygen me-
ter at various times throughout
the remainder of the winter to
take readings of the lake water's
oxygen content.
City and DNR staff began to
actively manage Lake Susan's
fishery in the early 19908 after
a public access became avail-
able. The DNR started to stock
the lake with fish, and they
proposed that aeration would
solve the period winterkills
that were wiping out the lake's
fishery. Lethal water for fish has
oxygen levels below two parts
oxygen per million gallons of
water. When the bame shoots
oxygenated water under the
ice, the water is about seven or
eight part per million.
City staff spent Wednesday
morning placing fencing and
"thin ice" signs around the area
where the aerator is.
A lake
aeration
system
installed at
Lake Susan
is desIgned
to keep the
lake healthy
for fish
during the
course of
the winter.

To Director of Public Works
City of Chanhassen
In view of increasingly widespread environmental concerns, may I suggest a small
action that might have some merit. As you prepare for the spring and summer
maintenance programs, plan wherever you can to mow less. That's all.
Along roads and walkways where the mowed areas are up against unmowed areas,
reduce the mowed area by a few feet, even one foot less would be an advantage. Find
areas in parks and other public land that can be left natural, only a few square feet
perhaps, anything. There will be many places here and there where less mowing will be
acceptable to the public. In fact, there will be places where less mowing will likely not be
noticed at all by those who think everything should be mowed flat. One possible area to
mow less would be the right-of-way on the west side of Kerber Blvd. There are a few
unmowed areas now. Homeowners might be open to leaving more unmowed.
Further, encourage private landowners to mow less when that is possible. For example,
one such place is the hill north of Office Depot and TCF but south of the apartments.
Letting that area grow natural would inhibit rainfall runoff as well as improve growing
conditions for the plantings there.
There will be many advantages to mowing less: reduced maintenance costs, less runoff
into sewers, more habitat for birds and wildlife, healthier trees and shrubs, more
attractive natural areas, etc. I encourage you to do (or not do) whatever you can.
Sincerely,
~~'rL~

Dear Todd:
Thank you for your 2008 Minnesota Recreation and Park Association (MRPA) professional membership.
Since 1937, MRPA members have dedicated their time and energies to enhancing the parks and
recreation field in their communities and in the state of Minnesota.
MRPA communicates with members in a variety of ways, including web, print, and electronic media.
MRPA's website - mnrpa.org - has been updated with the new membership directory. The files are
located within the members' only section of the website, which requires a one-time member registration.
The directory is divided into the following groups: agency, board/commission, corporate, professional,
student, and retiree. Each group has been formatted into a PDF document which is available to download
and print. The website also lists MRPA's calendar of events within the Upcoming Events section.
The MRPA member magazine is mailed on a quarterly basis, with the next issue arriving in March.
Informational updates are emailed to the membership to provide us with the communication link regarding
the most current MRPA happenings.
There are several ways for you to become involved in MRPA: sections, committees, workshops, special
events, and conferences. Contact information is listed online at mnrpa.org for each section and
committee chairperson if you're interested in becoming further involved.
Members are the heart of our organization. Members are the reason MRPA exists. We strive to meet
members' needs as we work to further the role of parks and recreation throughout Minnesota's
communities. If you have any questions or comments, please contact me at 763.571.1305 x100 or
snider@mnrecpark.org. Again, thank you for your involvement with MRPA!
