1 Stream Ecosystem Assessment Group 1 Camp Caesar August 2003

2 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

6 Birch River - Stream Flow Channel Data –Wetted width = 9 m –Avg depth = 0.28 m –Cross sectional area = 2.45 m^2 –Avg velocity = 0.36 m^2 Discharge Q = 1.05 m^3/sec
