RMB Labs 2020 Year End Report

Annual "State of the Lake" facts and figures, trends and much more information.

Critical Habitat Map

  • Above is a link to the map provided by the Northern Waters Land Trust, created with the assistance of the Minnesota DNR, the Minn. Land Trust, the Nature Conservancy, and area Soil and Water Conservation DistrictsThe map will open to an area south of Woman Lake.  You can move the map to the northwest to locate Ten Mile Lake.  There is a "legend" link in the very upper left of the map that explains the color coding system.  The primary purpose of the coding is to assist the NWLT in prioritizing project applications for funding in the Clean Water-Critical Habitat program.  However, the NWLT is making this product available to its partners, such as lake associations and state and local agencies, for assisting in their conservation projects.  Only properties of 10 acres or greater are color coded in the map, as this is the minimum size considered cost effective for protection in the NWLT program.Zooming in on a color-coded parcel and clicking on it will open an additional box providing all pertinent info on that property (owner, acres, etc.).Note in upper left corner the three bars which serve as a legend for the map displayed. The layered icon next to it shows critical habitat and existing easements. When you click on the arrow it shows a legend.  Play with the base map icon to see topographic and  many other background information you can display. In the query box I typed "Ten Mile-Portage" to get map centered on Ten Mile Lake and surrounding area. The + and - allows you to zoom in and out on the map.  If you get lost, the home icon will restore you to the base map.

Zebra Mussels - link temporarily broken

  • The article above was published in the TMLA Winter Newsletter. Written by Bruce Carlson, it is a complete explanation of zebra mussels and their challenge to the lake.

Sensitive Shoreline on TML

  • The document above is about sensitive species of all types on and in Ten Mile that was put together by the DNR in 2008.  It is by far the best natural history document on Ten Mile Lake

Oak Wilt is coming!

  • Simple measures can prevent oak wilt (see video link above) and there are control options if it's caught early. But control can be expensive. Look for and report oak wilt in red oak trees on your property or in your neighborhood.
  • Oak wilt is harder to identify on trees in the white oak group (rounded lobes) and often requires laboratory testing.
