Opossum Lake, six miles west of Carlisle, Cumberland
County, Pa., will open to public fishing on Saturday,
June 15, the opening day of bass season in Pennsylvania.
A survey was made of the lake last fall by
Curtis Simes and Dan Heyl, fishery biologists of the
Pennsylvania Fish Commission. The survey was aimed
at determining the growth of bluegills, bass and crappies
over a period of a year.
Four large nets were laid at strategic parts of th e
60-acre lake to study growth factors and make othe r
observations of the fish. Biologists at the time said .th e
number of fish which have reproduced in the lake wa s
greater than anticipated but growth in size was less
than hoped for. Many legal size bass, bluegills, crappy
and sunfish were netted in the study. With additional
growth anticipated since the survey last fall, the opefii
ing day at the lake should be a banner affair for anglei' 5 '
NEW FLY-FISHING WATERS - Members of the Yello*
Breeches Anglers and Conservation Association, BoiMn9
Springs, recently placed "fly-fishing only" signs on a mi' e
section of the Yellow Breeches Creek in Cumberland County-
The group stocked 1,400 trout in this and other sections of th e
stream and plan to add more from fish being reared in Boil'
ing Springs lake trout pens.—Carlisle Sentinel photograph.
When hot, people seek shade or cool water. How about fisbi
a cold-blooded animal ?
In one study brown trout always lingered in water betwe e "
51.8° F. and 62.6° F. Evidently warm water is uncomfortabl e
to the browns and given a choice they will take cold water.
Browns will die when water temperatures exceed 80°. Specie 5
known as "warm-water fish" tolerate much warmer temperatures
