Recently awarded grants

Grants awarded 2019

In March 2019, the county awarded 10 grants totaling $176,000. Organizations will use funding to train volunteers to detect AIS early in lakes, expand inspections and outreach at public lake accesses, install boat cleaning stations, and fund research and education. Grants will support projects on more than 20 lakes throughout the county.

Reports and studies

AIS Prevention Aid Guidelines 2020-2025

Hennepin County has received funding from the State of Minnesota since 2014 to implement plans to stop the introduction or limit the spread of AIS. To receive funding, the county must establish guidelines for the use of the proceeds.

In 2019, adjustments were made to the county’s AIS prevention aid guidelines to direct the use of funds received 2020 through 2025. County staff engaged more than 60 stakeholders in evaluating the county’s AIS prevention programs, guidelines and funding options. Learn more about the evaluation by reading the Aquatic Invasive Species Program Evaluation Report.

Changes to the guidelines include:

  • Updating the goals to reflect the Natural Resources Strategic Plan
  • Defining the county’s best practices for public water access design
  • Emphasizing unpredictability in inspections
  • Setting funding by category goals to ensure the program is comprehensive
  • Funding of core program functions of enforcement at public water accesses and public access redesign project outside of a grant solicitation process to help partners with long-term planning and streamline administrative tasks to implement public access redesign work.

See the 2020-2025 AIS Prevention Aid Guidelines to learn more.

Lakes with limited access study

Hennepin County funded Fortin Consulting to survey 13 lakes and ponds without public boat access for the presence of aquatic invasive species. At least one aquatic invasive species was found in each of these waters, including curly-leaf pondweed, Chinese and banded mystery snails, and invasive carp and goldfish. The results from these surveys show AIS can spread into lakes without public boat accesses. These results highlight that efforts for prevention need to extend to multiple pathways.

Public access redesign study

The county has redesigned several public accesses using theories from behavior change research to prompt boaters to take proper aquatic invasive species prevention actions. The county commissioned an observational study to evaluate the effectiveness of the redesign in encouraging boaters to take action.

Key takeaways from the study include:

  • Redesigned accesses have better compliance rates
  • Redesigned accesses have better self-inspection rates
  • Redesigned accesses are successful at creating social norms and prompting action
  • Boaters behave differently when DNR inspectors are present
  • Data on tool use and timing can be used to improve AIS prevention programs
  • Traditional access signage has limited affect
  • Redesigning accesses can be cost effective way to prevent the spread of AIS

Based on the study results, county staff recommend expanding efforts to redesign accesses to promote aquatic invasive species prevention actions in conjunction with optimizing use times and creating uncertainty as to when inspectors will be present.
