The stream length surveyed in each stream varies based on sampling objectives and previous stream site surveys. The sites sampled in Marshalls Creek varied from 100 meters to 300 meters at each site. The Marshalls Creek stream survey objectives were to determine the distribution of both shiner species and define the habitat or area of stream that supports the shiner populations. A. A dry year or wet year would have minimal effects on sampling. Dry or drought years create stream conditions that make it easier to collect fish.
Wet years can decrease sampling efficiency because of the greater volume of stream flow.
The preferred habitat for shiners would remain the same regardless of rainfall. The individuals involved in the 1998 stream survey on Marshall Creek work for the Pennsylvania Fish and Boat Commission, the Department of Environmental Protection, the Pennsylvania Game Commission, the Department of Transportation, Frostburg State University, and Rettew Associates - a private environmental consultant . Q. Marshalls Creek already has two bridges in a short area. The proposed highway alignment that crosses Marshalls Creek includes multiple bridge spans. The area where these proposed bridge spans would cross Marshalls Creek is located in the upper reach of stream where both shiner species are present.
