[3] In 2014, a section of Roach River, which was viewed as essential nursery habitat for young fish, was temporarily dewatered during dam reconstruction on land owned by the Club.

The outlet dam is intended to provide a barrier against migration of white perch and smallmouth bass from Moosehead Lake.

Native rainbow smelt may fare poorly in competition with yellow perch which reached the pond after the dam was abandoned.

[2] Summer water temperatures are unfavorable for native trout which do poorly in competition with introduced yellow perch; but the Maine Department of Inland Fisheries and Wildlife stocks the pond with splake.

[13] The 40-acre (16 ha) Sixth Roach Pond is only 4 feet (1.2 m) deep and provides marginal trout habitat in comparison to thriving hornpout and white sucker.
