Page 3 provides a brief description of how to review the characteristics identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluatioa If a characteris[ic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and pruvide an explanation in the comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pastwe into a forest), the stream may be divided into smaller reaches that display more continuity, and a sepazate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with e score of 100 representing a stream of the highest quality. fii — Total Score (from reverse):T Comments: `v.. �er_ .£-,:r.� �:-,� ;.".z, � �.-_ � _._ ,. ..<,.._.�. i, ....i . .. � ,... ��.... +,o ...� _ r, _._i ._.,_�... !�r„ � � Evaluator's Signature � �.fl�.
