Canonsburg Lake in Washington County
was surveyed by Commission staff in late May and contained an excellent population of largemouth bass.
Quality-size bass were present in high numbers with 27% of the bass over 15 inches. Most of the bass
were collected in the lower end of the lake between the bridge and the dam breast. This impoundment
would be a great place to target largemouth bass.
Channel catfish were collected in good numbers and sizes. The Fish and Boat Commission stocks channel
catfish, muskellunge, and tiger muskellunge fingerlings along with trout. Muskies and tiger muskies were
not collected during the survey. They may have been in deeper water due to the warm water temperatures
or their populations may be low. Crappies were collected in good numbers but quality size fish were
lacking. Overall, panfish populations were well below average. This is probably a result of competition
with gizzard shad. The majority of trout were collected in the shallower upper-end of the lake.
