For example, the only size 3 portfolio river with no dams on its mainstem to theocean, potentially the most functional network example in the portfolio, is the Taunton River.Some rivers were included in the portfolio for connectivity purposes, but are were coded as Sxcbecause the team felt they did not meet the criteria for a S1 (best) or S2 (good/second best) rankwithin their system type given their current condition. These Sxc examples usually contain manydams or have other serious current condition problems making them poor examples of their type,but they are still necessary if functional networks are going to be restored for all size threesystem types. Sxc rivers that were identified as part of the portfolio include the Chicopee,Blackstone, Concord, Nashusa, Contoocook, Sugar, Ammonoosuc, Wild Ammonoosuc,Passumpsic.SHORTNOSE STURGEONSTRIPED BASSWHITE PERCHGrand TotalREVISED 6/2003AQUA-RESULTS-40
