Boat Access Redesign with CD3 Systems
By Hennepin County Environmental Services
When used with signage, a clean out location, and road lines, CD3 Stations can reduce AIS violations rates by more than 70%.
Violation rates decrease over time as behavior adoption increases.
CD3 Water Removal Study:
By University of Minnesota’s Minnesota Aquatic Invasive Species Research Center (MAISRC)
Despite compliance with standard drain plug regulations, residual water remained in all boat types and in all compartments examined; however, the risk of residual water was reduced by using the CD3 Station vacuum.
While not 100% effective for all boat types, this demonstrates potential value to reduce the risk of AIS spread between lakes by promoting a more extensive and comprehensive approach to water removal.
Minnesota Case Study
Five Waterless Cleaning Stations 2017-2018 Pilot Outcomes
Clean-Drain-Dry-Dispose (CD3) Waterless Cleaning Stations provide free tools empowering day-boaters to take action to prevent the spread of Aquatic Invasive Species (AIS). The stations are a waterless, free, user operated cleaning equipment including wet/dry vacuum, blower, and tethered hand tools. Internet connected, the stations log use, maintenance, and functionality.
Successfully piloted in Minnesota at five locations, CD3 Station software logged over 6,500 volunteer AIS prevention actions taken by boaters (approximately 2,200 watercraft). Accessible 24/7, CD3 Stations have been proven to extend AIS budgets.
CD3 Station Sites: five locations spanning urban to rural geography & watercraft users:
Lake Minnnetonka, Spring Lake Bay Hennepin County
Lake Minnnetonka, North Arm Bay Hennepin County
Bryant Lake, Three Rivers Park District
Pike Lake, Canosia Township
Lake Riley, City of Eden Prairie
Launch Managers: Municipalities, township, park district & county,
Targeted AIS: zebra mussels, eurasian water milfoil, starry stonewort & spiny waterflea
Over 28,400 Total Uses in 2 Combined Field Season
Highly visible AIS engagement and awareness tool for visitors
24/7 accessible equipment provides $50,000+ value, if paid $12/hr/year
7+ year asset at low operational cost of septic & electrical ~ $250/season
Use metrics and maintenance alerts via MyCD3Station.com software
Technology options for boaters to CD3 “check in” and “check out” at a launch
“I really like the brush and squeegee to clean my bunks and side of boat.” -Todd H., Lake Riley angler
“I was really impressed with the use by boaters, it has exceeded my expectations.” -Tony Brough, Hennepin County AIS Manager
“We were are very happy with the use by boaters at the launch and functionality of CD3 equipment.” -Brian Vlach, Three Rivers Park District, Senior Water Resource Manager
"The future is this type of equipment, it really has gotten used by boaters." -Kevin Comnick, President Canosia Township
“Education & awareness can go only so far, CD3 provides the resources for boaters to take action.” - Pat Cozemius, Conservation Director Wildlife Forever
