Work at Pleasant Valley began in the summer of 2007. The 2-mile project area consisted of several reaches with wide, shallow channels with little flow, resulting in silt settling over gravel substrate, providing little habitat for invertebrates and fish.  In-stream and riparian rehabilitation in conjunction with upland conservation practices have reduced sediment inputs to the stream and will likely provide long-term ecological effects.  The 2007 project involved removing woody vegetation (invasive boxelder trees) in the project area, stabilizing eroding streambanks, constructing and installing LUNKER structures to provide overhead bank cover for trout and seeding banks with native vegetation.  Fish response to these habitat improvements on Pleasant Valley has been positive.  The fish community has shifted from a warmwater community to a coldwater fishery dominated by mottled sculpin, American brook lamprey and brown trout.  Dane County and the WI DNR will continue to monitor water temperature and fish communit y health.  If stream conditions at Pleasant Valley Branch continue to improve as anticipated, the WI DNR and Dane County will propose to remove the site from its list of impaired waters.
