Did you Know?

A legislative change effective Aug. 1, 2007 extended the expiration date of 2007 fishing licenses for resident and nonresident anglers through April 30, 2008, according to the Minnesota Department of Natural Resources.

Any stamps or tags to harvest particular species also are valid through April 30, 2008.

Angling licenses, stamps and tags for 2008, which will be effective from March 1 through April 30, 2009, went on sale Feb. 18.

Fishing licenses are required for resident anglers age 16 and older and all nonresidents. Nonresidents younger than 16 may fish without a license if a parent or guardian who is licensed accompanies them.

Steelhead Habitat Study

MN DNR stream habitat study is underway...

Throughout the summer of 2007, Tracy Close, with student intern, Roger Peka, installed 24 pieces of large wood to determine if such structures could improve habitat for trout in North Shore streams (see image).

Pieces were placed in the West ranch of the Split Rock River, Upper Knife River, Little West Branch of the Knife River, and French River. Since few large trees are available in North Shore riparian zones, smaller trees were cut, pulled into the river channel using a chainsaw powered winch and bundled together with cable to simulate large trees. "We anticipate that if the pieces remain in place, flood flows will scour a pocket below the piece as it diverts flow to the center of the stream and smaller pieces of wood will accumulate upstream of the large piece providing nutrients and overhead cover for fish." Changes to stream substrates and fish abundance will be monitored for several years to determine if the anticipated benefits occur.
