Loyalhanna Creek & Conemaugh River Basins
Search for Wild Trout
Westmoreland & Indiana Counties
 
June & July 2010

Biologists from the Area 8 Fisheries Management Office in Somerset surveyed 21 unassessed waters in the Loyalhanna Creek and Conemaugh River basins in Westmoreland and Indiana counties in summer of 2010.  The surveys were conducted as part of a statewide effort to document wild trout populations in unsampled streams in areas facing pressure from human encroachment or mineral extraction. Further details on the process can be found at these links (Area 7 unassessed streams or Area 8 unassessed streams).

Sampling was conducted during June and July 2010 using backpack electrofishing gear. Table 1 below lists the streams surveyed and whether or not the presence of wild trout was documented.

Of the 21 streams surveyed, eight streams were documented as supporting wild trout. Many of the streams surveyed do not support fishable wild trout populations, but possess water quality and habitat suitable for wild trout reproduction. However, some of the streams supported substantial populations and contained abundant access for fisherman on public lands.
