Why invasive species matter

Aquatic invasive species (AIS) such as Eurasian watermilfoil, starry stonewort, and invasive mussels threaten Higgins Lake’s water clarity, native habitat, recreation, and long-term health. Once established, these species are extremely difficult—and costly—to control, making prevention and early intervention essential.

What HLPOA is doing

The Higgins Lake Property Owners Association (HLPOA) has taken a leadership role in invasive species prevention and control for decades, working closely with scientists, partner organizations, and lake residents. Taking actions such as:

Scientific Studies & Early Detection

Scientific Studies & Early Detection

  • Supported and promoted lake-wide surveys to identify invasive species early, including Eurasian watermilfoil and starry stonewort.
  • Helped establish baseline data to guide long-term, lake-specific management strategies.

Integrated Management Approach

Integrated Management Approach

  • Supported biological controls (milfoil weevils), physical controls (benthic barriers and hand removal), limited spot treatments, and ongoing monitoring.
  • Advocated for approaches that are effective, cost-efficient, and environmentally sound.

Boat Launch Risk Reduction

Boat Launch Risk Reduction

  • Partnered with the Higgins Lake Foundation (HLF) to educate boaters at DNR launches about aquatic invasive species. Volunteers provide information, answer questions, and collect data to better understand how invasive species enter and spread within Higgins Lake.
  • Supported boat wash programs, signage, and education at access sites.

Advocacy & Accountability

Advocacy & Accountability

  • Actively urged the Michigan Department of Natural Resources to partner in addressing invasive species risks at DNR-controlled access points, where dense infestations have been documented.
  • Called for responsible stewardship, prevention, and long-term planning at state-managed launch sites.

Education & Outreach

Education & Outreach

  • Provided educational materials, signage, and community communications emphasizing Clean, Drain, Dry practices.
  • Encouraged residents and visitors to inspect boats, trailers, anchors, and gear every time they enter or exit the lake.

Why this work matters

Without consistent action:

  • Native plants and fish habitats are lost
  • Shorelines become choked with weeds and algae
  • Recreation and property values decline
  • Long-term management costs increase permanently
HLPOA’s efforts focus on prevention first, because stopping invasive species before they spread is the most effective and affordable solution.

Ever wonder what the bottom of Higgins Lake really looks like? The answer may surprise you. Join Mark Luttenton, PhD, as he narrates the exploration of plant growth discovered by divers at the north shore. This Higgins Lake Foundation curated video takes you to depths of 25-35 feet so you can learn about the significant changes that have occurred in Higgins Lake.

What you can do

Prevention is Our Best Defense

Clean

Drain

Dry

Clear all plant, debris, and aquatic organisms from boats and trailers
Remove drain plugs and drain all water (bilges, ballast tanks, and live wells)
Allow boats and equipment to dry for at least 5 days in the sun before launching in a new body of water
