Dakota County and Goodhue County Lake Byllesby Regional Park Master Plan
Byllesby Reservoir and Public Motorized Watercraft
October 27, 2017
The Minnesota Department of Natural Resources (MnDNR) manages surface water usage and motorized
boating in Minnesota and has implemented a guideline for the number of parking places available at
public launching facilities. The MnDNR guideline is one public boat parking space per twenty acres of
surface water on any given waterbody. The guideline accounts for boat access from private docks in
addition to access at public launching facilities.

The guideline for public boat parking is based upon the nature of lake use. For example, should a
specific lake have surface use restrictions on speed, additional parking capacity could be warranted.
The guideline is referenced in Design Handbook for Recreational Boating and Fishing Facilities – Second
Edition published by the States Organization for Boating Access, 2006. For more information, contact
Kent Skaar, Senior Project Manager, MnDNR Parks and Trails Division.

The Byllesby Reservoir is 1,368 surface water acres. Surface water acreage of a Public Waters basin
corresponds to the Ordinary High Water Level (OHWL). Using the guideline of one public boat parking
space per 20 acres of surface water, the guideline number of public boat parking spaces for the
Reservoir would be 68 (1368 surface water acres/20). The Draft 2017 Master Plan recommends
maintaining the same number of public motorized boat craft on the Reservoir as today, summarized in
the table below. For more information on the Draft Master Plan recommendations, contact Lil Leatham,
Dakota County Senior Planner ( or Greg Isakson, Goodhue
County Public Works Director (

Carp on carp crime: Let’s use koi to clean up Minnesota Waters

Not long ago, the Free Press, as well as many other news outlets, reported on the Lake Elysian
carp koi kill, the result of a koi herpes virus (KHV).

Minnesota Department of Natural Resources officials speculate the virus was present in the
Waseca County lake due to someone releasing a goldfish or koi from a home aquarium or

As the news of the fish kill made the rounds, many articles focused on why the carp died, but
never stated how amazing it is that this disease had no effect on the other fish species in the

Most people recognize the common carp as a nuisance or rough fish. They leave them on the
shores with the belief the practice will eliminate one more rough fish from their favorite fishing
hole. According to the University of Minnesota’s Aquatic Invasive Species Research Center, a
single female can carry 3 million eggs in a lifetime-basically the catch and kill practice is as
effective as “using paper towels to catch water”.

Another fun fact about carp-the invasive species destroy ecosystems. MASRC research shows
that the common carp are more damaging to water quality than human watershed
development. How?

Researchers analyzed data from over 2,000 Minnesota lakes, covering three major ecoregions
of the Great Plains, Eastern Temperate Forests, and Northern Forests. They also conducted
whole lake experiments in six lakes in which they established what the current carp
populations were, surveyed plant cover and identified species richness both before and after
removing carp.

Researchers found that when common carp were prolific, plant cover was reduced to
less than 10 percent and species biodiversity was halved. By analyzing the impacts of
other human-caused stressors, the researchers revealed that carp had a GREATER
IMPACT on aquatic plant biodiversity than human watershed development did (urban and

The study also showed that removing common carp increased plant cover, species
richness and water clarity.

In our region of the state, this research is important. Carp burrow into lake sediments and in
the process uproot aquatic vegetation, increasing water turbidity and releasing large
quantities of sediment-bound nutrients, which stimulate algal blooms.

MAISRC estimates more than 70 percent of the lakes in southern Minnesota have lost their
plant cover and suffer from excessive algal blooms due to carp’s foraging activity. Common
carp also have a devastating impact on waterfowl habitat.

While those who combat common carp have focused on the reproductive cycle to eradicate
the fish, or have engaged in seining, I’m convinced researchers need to further examine the
first-known introduction of KHV in a wild fish environment in Minnesota. If KHV can wipe out 
large populations of carp in a wild fishery without harming other species of fish, why not
study it more to see if it can be safely replicated?

Replicating the virus without introducing actual koi to Minnesota lakes could be part of the
process of eradicating common carp. Operation Koi would be phase one. Phase two would be
controlling the spawning grounds in shallow lakes and wetlands where carp are able to move
to other bodies of water. And phase three would be the introduction of a bluegill stocking

MAISRC research shows that lakes with high populations of bluegills have low populations of
carp because bluegill feed heavily on carp eggs. And for those of you asking if sunfish would
do the trick, the answer is yes, because bluegills are sunfish.

Common carp are a difficult problem to solve, but one that needs to be examined as the state
pushes to improve its water quality. To ignore the possibilities of KHV would be a mistake.

Besides, its only a matter of time before a passionate Minnesota angler decides to break the
law and release koi into his or her favorite fishing hole, regardless of if the fish are infected or

Let’s save Minnesota anglers from themselves and study the possible benefits of KHV.

Note: Byllesby anglers have reported increased numbers of sunfish/bluegills caught in
the past few years as carp have been systematically been removed from the lake. Algae
blooms have also been noted as being less frequent.

Governor Dayton Holds Townhall “Water Quality” Meeting

posted Sep 13, 2017, 3:08 PM by ByllesbyAssociation

Wednesday, October 4 6:30-8:30
Diamondhead Education, 200 w. Burnsville Pkwy.
Registration opens at 5:30 P.M.

This meeting, called by Governor Mark Dayton is one of 10 Water Quality Town Hall meetings held across the state this fall.  Across much of Minnesota, the discussion has been about lakes and rivers impaired by excess phosphorus and nitrogen, too much road salt, invasive species, declining water tables due to overuse and the need for buffer strips to keep farm runoff out of rivers.

The meetings are part of Dayton’s effort to improve water quality by 25 percent by 2025 across the Land of 10,000 lakes, where in some southern regions, three-fourths of the waters are unsafe for fishing, drinking or swimming. “It’s going to take decades” to recover southern Minnesota’s most degraded waters, Dayton said.

ALL L.B.I.A. Members are encouraged to attend.
