BIOLOGIST REPORT

Chambers Lake


Chambers Lake, located in Hybernia County Park, Chester County was surveyed in October 1999 by Pennsylvania Fish and Boat Commission biologists in an effort to:

  1. continue to monitor the development of the fish community in this recently created impoundment, and
  2. begin to monitor changes in the fish community following the official opening of the lake to angling (June 12, 1999).

Ten Pennsylvania style trap nets fished for an average of 21.8 hours each and one complete circuit of the lake’s shoreline during night electrofishing efforts were used to sample the lake's fish populations.  The total catch of bluegill, pumpkinseed, and black crappie were at levels similar to other lakes in southeast Pennsylvania.  These populations appeared to be stunting however, with few individual fish larger than 7 – 10 inches present in the catch.  Chain pickerel were collected in good numbers with individuals in the 20 – 26 inch range common.  The yellow perch population was moderate with fish up to 10 inches long captured with most fish being 7 – 9 inches long.  Few catfish (including channel catfish and brown bullhead) were collected.

The statewide management objectives for bass include:

  • A total catch of 35 bass per hour of electro fishing,
  • A catch rate of at least seven bass larger than 12 inches per hour
  • A catch of at least 2 – 3 bass per hour which are greater than 15 inches
  • There rates were met and exceeded in Chambers Lake.  The Chambers Lake electrofishing effort yielded a total catch of:
  • 69 bass per hour
  • 21 bass per hour larger than 12 inches
  • 6 bass per hour larger than 15 inches.
  • Efforts to improve the panfish fishery at Chambers Lake have been made.  Recently white crappie have been stocked into Chambers Lake in favor of black crappie.  White crappie may be better adapted to the seasonal temperature and oxygen conditions in Chambers Lake.  Additionally, biologists have attempted to develop a naturally reproducing population of forage fish through the stocking of spotfin shiners.  This, along with the appearance of aquatic vegetation, which provides suitable habitat for aquatic insects, should help to increase the growth rates of bluegill and other panfish.  The Pennsylvania Fish and Boat Commission has continued to stock channel catfish in an attempt to improve the catfish fishery.

    In general, biologists were very pleased with bass, chain pickerel, and yellow perch populations and will continue to work toward improving the other panfish fisheries.
