Biologist reports logo Native Brook Trout Streams

Northeast - Pocono Region
Summer 2004

During the months of June, July and August, the staff of Fisheries Management Area 5 conducted stream surveys on the following Wilderness Trout streams: Kistler Run, Wolf Swamp Run and Jeans Run. The surveys were performed to provide additional baseline data prior to placing these streams into the Brook Trout Enhancement program effective January 1, 2005. Previously established sites, one per stream, were reexamined during this period. The length of each site was 300 m (or 330 yards).

The average estimated abundance of brook trout seven inches and longer, and for those nine inches or greater statewide in freestone streams with limited fertility is 34 and 4 trout per stream mile, respectively (2002 Trout Summit). In 2004, surveys revealed that the estimated number of brook trout seven inches and longer in each stream is above the statewide average. However, no brook trout nine inches or greater in length were present at the time of the surveys.

Kistler Run in Monroe County ranks in the top ten percent of Pennsylvania’s freestone brook trout streams. Streams residing in this category contain at least 82 trout per mile seven inches and longer (2002 Trout Summit). The estimated number of brook trout seven inches and longer in 2004 and 2003 was 109 and 143 per mile.

Wolf Swamp Run in Monroe County placed in the upper quarter of Pennsylvania’s freestone brook trout streams. Waters placing in the state’s top 25 percent contain at least 46 to 81 trout per mile seven inches and longer. In 2004, the estimated number of brook trout seven inches or longer present was 48 per mile.

Jeans Run in Carbon County falls among the state’s upper third freestone brook trout streams. Streams falling within this category contain 36 to 45 trout per mile seven inches and longer. The estimated number of brook trout seven inches and longer per mile in Jeans Run is highly variable. Their abundance fluctuated from 47 in 1992, to five in 1993, and rebounded to 43 trout per mile in 2004. No brook trout nine inches and greater in length were caught during this survey, but they were present in 1992. The native brook trout population and fishery in Jeans Run can at times be adversely affected by acidic conditions, especially during the spring run-off period.
