Orleans, IA (Northwestiowanow.com) — Knock on wood – a prominent invasive weed has not shown up this summer in the Okoboji chain, but DNR Fisheries Supervisor Mike Hawkins says it is in the corridor.

Hawkins tells KICD’s George Bower the trick is to attack the weed with a chemical that’s not dangerous to people, aquatic creatures, or desirable vegetation.

The Iowa DNR constantly asks boaters to clean, drain, and dry their boats and trailers before moving between water bodies.
