very little aquatic growth | Brinckerhoff dam | Imp-A = 9; Imp-B =10; Imp-C = 9; Imp-D = 10; Helin Rd =9 | saw very little aquatic growth and algal growth | water quality varies independent of weather, algal growth increases upstream | algae more prominent above Carpenter Rd. bridge, creek runs clear downstream from diversion/ dam; Fanwort?

Each would totally prevent fish migration up/downstream, within segment, there are no barriers | no barriers within segment itself, but note Texaco dam approx 1 1/2 mi. downstream and Beacon dam approx 2-3 mi. downstream, each presents impossible obstacle to fish movement; distances exagerated, eg Texaco dam is less than a half mile downstream - RO) | some blowdown that crossed entire stretch near Clove Creek but may not impede fish movement | no barriers in this section; however there is a dam at Brinckerhoff and in Beacon | Brinkerhoff Dam, total blockage | difficult to see due to depth and turbidity | Imp-A = 10; Imp-B = 10; Imp-C = 10; Imp-D = 10; Helin Rd = 10 | saw lots of minnows to legal size trout, numerous fallen trees that did not completely block stream | no barriers | natural diversions within stream with ledge drops under 1 ft., water levels rarely drop to impede fish passage, dam eroded and water moves over and around | one stone wall with 1/2 foot drop (large waterfalls = impaired site); ( 2nd large dam exists at the S end of segment- RO) (1/2 foot drop appears to be bedrock- RO) | one old structure may block movement during low water conditions.

Imp-B = 10; Imp-C = 10; Imp-D = 10; Helin Rd = 10 |

portion of segment is heavily forested |

| - Embeddedness | along the upper reaches of our segment we did not encounter a good amount of cobbles; the portion that was cobbled was 50% embedded | very few areas in which this score would apply, as only one significant stretch of riffles shortly above Jean Van Pelt park close toOld Town Rd. at beginning of segment. Other deeper, slower areas are deeply sedimented | only one area to evaluate with minimal riffles over shallow gravel beds | riffling of streambed evident in approx. 6 places along segment | Imp-A = NA;
