WSUM Task Force
Policy Issues Addressed
Goals of WSUM
•Accommodate all compatible recreational uses
where practical and feasible;
•Minimize adverse impact on natural resources;
•Minimize conflicts between users in a way that
provides for maximum use, safety, and
enjoyment; and
•Conform to the state standards.
Lack of knowledge of rules. There is not a specific group that lacks the knowledge but
rather boaters of all experience levels have different understandings
Variety of Users: Many people only launch their boat once per year (those who live on
the lake or have a dock on the lake).
Boat Renters: The My Boat Club on Prior Lake has enhanced their training program
and all users must ride along with a manager around the entire lake before using the
boats.
Training for Youth: The Prior Lake Association and Community Ed and Rec annually
hold a DNR sanctioned boating safety training for youth.
Top 3 WSUM violation issues (from Sheriff’s Office):personal watercraft, watercraft
lighting violations, slow no-wake violations.
Education
Outcomes from Task Force:
The Task Force recommends increasing education efforts.
Focus on top 3 WSUM violation issues (from Sheriff’s Office): personal watercraft,
watercraft lighting violations, slow no-wake violations.
Create a Task Force to create an educational program that would tap into existing
resources of lake and homeowner associations.
The WSUM Task Force generated ideas for education efforts:
Targeted groups
Install consistent & updated signage at all public boat launch sites; look into
posting signs on CR 21 bridge
Create a guidance document for property owners relating to slow no-wake
buoys and the existing County permit program
Education
Patrol
Prior Lake is one of the 10 most highly used lakes in the state.
The Sheriff’s Office has exclusive responsibility for water patrol.
There are trained reservists but they must be accompanied by a Sheriff’s
Office Deputy at all times.
Prior Lake has enforcement presence 4 days per week.
No lakes, other than Prior Lake, have regularly scheduled patrols.
The DNR filled their Conservation Officer position after a 4 year vacancy and
now helps with enforcement (DNR CO is county-wide position).
The Sheriff’s Deputy must see a violation in order to enforce it (photos,
reports, etc. are not enough).
Enforcement
Buoys
Prior Lake has a number of regulatory or warning buoys that mark hazards
and no-wake zones. The Sheriff’s Office stores and places these buoys.
The County applies for grants to purchase buoys and other equipment
including boats on a regular basis.
Private property owners can purchase marker buoys (orange ball shaped) to
mark the 150’ no wake Zone. Property owners are responsible for their own
buoy, chain/rope, and weight.
Anyone can apply for a permit to place a buoy in front of their private
property.
Marker buoys are not all placed accurately and there is not consistent spacing.
Enforcement
Outcomes from Task Force:
A majority of the Task Force members agreed that there is currently sufficient
enforcement on Prior Lake. However, there needs to be better delineation of
the 150’ no-wake zone to achieve a higher level of compliance.
Some task force members felt that enforcement is not adequate and that
measures should be undertaken to increase the amount of overall rules
enforcement.
A majority of the Task Force agreed that Spring Lake needs additional
enforcement.
There was concern about response time when the lakes are not being actively
patrolled.
Enforcement
Time of Use
Close calls and other towing conflicts during the hour after sunset were a
concern of the patrol officer.
State law was recently changed to prohibit towing ½ hour after sunset.
The City ordinance currently prohibits towing 1 hour after sunset.
Towing
Members noted that towing people through officially marked slow no-wake
zones is a potential safety hazard.
Crowding
As use on the lake goes up, crowding on the lake and its impact on public
safety has become a concern.
Public Safety
Outcomes from Task Force:
Time of Use
All Task Force members agreed that the WSUM regulations should follow the new state
law for towing (changed from 1 hour after sunset to ½ hour after sunset); this law is
currently in place and supersedes the current Prior Lake rule.
Towing
Restrict all towing through slow no-wake zones on Prior Lake
Crowding
The task force suggested reviewing other models that use parking restrictions to limit
boats on the lake (allow one boat per parking space).
Public Safety
Impact on Water Quality
Regardless of the delivery method (e.g., erosion, resuspension, wave
action, etc.), sediment impacts water quality similarly.
Sediment from shallow lake areas and shorelines are low in releasable
phosphorus.
Aquatic plants can help to trap fine sediments and stabilize the lake
bottom.
Impacts of Waves
Wave Energy
Both Spring Lake and Prior Lake are seeing an increase in more intensive
uses (wake boarding, wake surfing, etc.).
Wave energy is greater when boats are accelerating or decelerating.
The DeWitte Public Access area has more shoreline impacts than other
areas of Prior Lake.
Shoreline stabilization practices are changing on Prior Lake.
Impacts of Waves
Outcomes from Task Force:
WSUM regulations likely have a minimal impact on overall water quality
(phosphorous)
About 60% of the Task Force was in favor of restricting the operation of boats in a
bow high manner in the area south of Twin Isle.
The remaining Task Force was not in support of restricting uses around the DeWitte
Access.
The Task Force recommends creation of a guidance document for shoreline
stabilization.
Impacts of Waves
Statewide goals for WSUM include:
Accommodating all compatible recreational uses where practical and
feasible
Minimizing adverse impacts on natural resources
Minimizing conflicts between users in a way that promotes maximum
use, safety, and enjoyment
Task Force members noted that passive uses, such as paddle boarding and
kayaking take place in the early morning hours or during the week when
there are fewer active users.
Active use boaters are generally respectful of fishing boats.
Recreational Opportunities
Outcomes from Task Force:
Recreation was central to all discussions during the Task Force meetings;
therefore, no Task Force recommendations are specific to recreational
opportunities alone
Some members would like to see a “No Wake Wednesday ”
Recreational Opportunities
There is currently no high-water no-wake restriction on Spring Lake.
Spring Lake residents have seen an increase in the amount of boat traffic.
Spring Lake residents have seen an increase in the intensity of active uses.
The lack of a regulated no-wake zone creates a safety hazard for
swimmers.
It is beneficial for compliance to have consistency of permanent
regulations between Spring Lake and Prior Lake. High-Water provisions
should be based on individual lake characteristics.
Spring Lake Regulations
Outcomes from Task Force:
A majority of the Task Force members living on or using Spring Lake agreed
that Spring Lake should have the same WSUM regulations as Prior Lake.
The City of Prior Lake and Spring Lake Township must pass equivalent
WSUM ordinances.
The ordinances would include the provision that a temporary, lake-wide
slow no-wake requirement is enacted when the water levels reach the
Ordinary High Water elevation (912.8’).
Spring Lake Regulations
Major WSUM Recommendations
1.Update Ordinance
2.Education Task Force
3.Buoy Placement
4.Spring Lake Enforcement

•Adoption of Ordinance
Questions
1.Do the Board and Council support the ordinance language as
presented?
2.Do the Board and Council support the creation of a Task Force to
facilitate the education process and work with existing stakeholder
groups (i.e. Lake associations and HOAs) to promote the messages.
3.Do the Board and Council support the need for additional
enforcement? Should this be addressed at the City, County or
SCALE level?
4.Do the Board and Council support creation of a mechanism to
ensure adequate placement and spacing of buoys around the
lakes?
