Black River Targeted Watershed Assessment, Douglas County

Purpose

The Black River and Little Black River in Douglas County were monitored to further document their high quality. The watershed is 94.4% undeveloped. Pattison State Park and Pattison Falls, Wisconsin's highest waterfall are located on the river. Three sites on the Black River and one site on the Little Black River have excellent IBI's for both fish and macroinvertebrate communities. They appear to be excellent candidates for applying the proposed protection tier for tiered aquatic life uses (TALU). HUC12s include 040103010302, 040103010303, 040103010304.

Objective

Project need, management questions, and specific information from sites to be addressed are described in the purpose section above. There are 8 sample sites, the Black River WBIC is 2836900, the Little Black River WBIC is 2839900.

Outcome

1. There are 8 sample sites 2. There will be 4 sampling events in FY16 and 9 sampling events in FY17. 3. Sample collection completion date is November 30, 2016. 4. Can't predict when all data will be entered in database due to uncertainty of when macroinvertebrate analyses by lab will be done. Could be late in 2017. 5. Final report possible by May 15, 2017, but depends on macroinvertebrate analyses timeline. 6. Data bases to be used for data storage are SWIMS and FHDB. 7. Person responsible for data entry is Craig Roesler.

Study Design

Fish surveys, macroinvertebrate samples, qualitative habitat assessments, and water quality data will be collected from 8 sites (see map in documents section). Water quality data will include nutrients, TSS, and field parameters - temp, DO, pH, cond., transp., flow. The Black River site near the mouth will have 6 monthly (May-Oct) samples collected for nutrients and TSS, along with field parameters. Six sites are on the Black River and two sites are on the Little Black River. One diatom sample will be tested from the near-mouth site on the Black River. Craig Roesler will be the lead biologist for the project. Five sites have established SWIMS no.'s. Three additional sites have been identified, and will have SWIMS no.'s assigned after they are field verified.
