Colver Reservoir 


The 75-acre Colver Reservoir in Cambria County, also known as Vetera Dam, was surveyed by Commission biologists in April.  The survey included six trap net sets, six gill net sets and two night electrofishing runs

Since 1996, the PFBC has stocked the impoundment with equal numbers of walleye and saugeye (walleye/sauger hybrid) fingerlings annually, except in 1998 when three times more saugeye than walleye were stocked. Both fish species were collected during the survey with three times more saugeye than walleye collected. The size of the majority of walleyes and saugeyes most likely corresponds to the 1998-year class. Colver Reservoir would be a good place to target walleyes and saugeyes in coming years as the population increases through PFBC stockings. 

Bluegills, black crappies, yellow perch, and bullheads were collected in low to moderate numbers with quality size fish present. 

The lake had a moderate density of largemouth bass. Quality size bass were lacking, though,  with only one bass over 14 inches.

White suckers were collected in high numbers and quality sizes. Colver Reservoir would be an excellent impoundment to target large white suckers.
