Upper Tomahawk (UW38) Watershed Planning

Purpose

The Upper Tomahawk River Watershed is located in Oneida and Vilas counties. It is 119,568 acres in size and contains 139 miles of streams and rivers, 17,609 acres of lakes and 20,470 acres of wetlands. The watershed is dominated by forest (59%), wetlands (17%) and open water (14%) and is ranked high for nonpoint source issues affecting streams and lakes.

There is a globally significant concentration of glacial lakes in the Northern Highland: 4,291 lakes; 1,543 miles of streams, including the headwaters of the Wisconsin and Manitowish-Flambeau-Chippewa river systems. Many lakes are connected by small streams. Rare aquatic species and extensive wetlands (see below) occur here.

Study Design

Watershed specified for planning and assessment purposes. Assessment of water quality condition in this respective county will use protocols described in WisCALM of the year of assessment. Minimum assessment work includes biological data (macroinvertebrates, fish indices), chemistry and habitat data. Additional work includes identification of priorities and goals, creating recommendations for actions, and updating narratives for watersheds and waterbodies. Assessments are to be double checked by at least one additional biologist.
