Hubbard County AIS List

Hubbard County AIS List


Various Aquatic Invasive Species (AIS) have been present in Hubbard County lakes and rivers for many years.  According to the Minnesota DNR’s Infested Waters List and the Early Detection & Distribution Mapping System (EDDMapS) the first observations of AIS in Hubbard County were confirmed by the DNR in 1995 when Curly-Leaf Pondweed was confirmed to be in Hinds, Portage and Upper Twin Lakes. 

Species such as Banded & Chinese Mystery Snails which are popular aquarium species had been introduced likely from aquarium dumping, and confirmed in various Hubbard County lakes throughout the early 2000’s and are still being reported in new lakes as recent as 2017.  First confirmed in 2009, Faucet snails are a unique AIS that has no adverse effects on fish species or water quality, but they are an intermediate host to a number of flukes, which are a deadly parasite that kill waterfowl when they feed on the snails.  It is a common misconception that Faucet Snails do not affect the Loon population that we enjoy in the summer months in Hubbard County, because Loons primarily feed on fish.  However, Loons are opportunistic hunters that will feed on small crustaceans, mollusks and snails when the opportunity presents itself, so Loons are effected too.

2017 was a big year for AIS in Hubbard County when both Eurasian Watermilfoil was confirmed in Bad Axe Lake, and Zebra Mussels were confirmed in Benedict, Garfield, and Steamboat Lakes.  Eurasian Watermilfoil and Zebra Mussels are both new AIS to Hubbard County and pose challenges for all users of the lakes where they have infested. 

Additionally in 2017, Faucet Snails, Banded/Chinese Mystery Snails and Curly-Leaf Pondweed all had been confirmed in new bodies of water throughout Hubbard County, although these populations in many cases have been established for quite some time. 

It is important to remember to Clean, Drain, and Dispose when using lakes and rivers in Minnesota.  Public water users can cut down on the risk of spreading invasive species by draining all water from their equipment, cleaning off any vegetation on their equipment, and disposing of unwanted bait.  See the below document to view the comprehensive Hubbard County AIS List.
