Group 1 Study Sites Birch River Craig’s Run Big Rough Run South Fork Cranberry River
3
Birch River – General Description Watershed –Elk River –48.41 km^2 –Mixed (Ag., Forest, Residential) –Moderate NPS; low local erosion 3 rd Order Perennial Coldwater stream LB: Forest (Sycamore, Alder);RB: Narrow Riparian Zone (due to road) Low LWD Aquatic Veg. (Sedge: 2%, Biofilm: 85%) Sediment Type – Boulder/Cobble Bed
4
Birch River – General Description Geology –Stream origin: Non-Glacial Montane –Rock types: Pottsville sandstone – low buffering cap. Conemaugh shale – moderate buffering cap.
5
Birch River – General Description Sampling Conditions –Cloud Cover: 90% –Air Temp: 75 F –Hvy rainfall in last several days Visual Condition –High canopy cover –Low erosion stream banks adj. road
