Fish Stocking Activity

Fish Stocked by Species for the Last Ten Years

Year Species Size Number Pounds
2012 Walleye2 fingerlings 3,784 204.0
2010 Walleye1 fingerlings 3,133 204.0
2008 Walleye1 fingerlings 6,680 200.0
  Walleye fingerlings 128 4.0
2006 Walleye1 fingerlings 3,750 250.0

Stocking Notes
1 - indicates fish purchased and stocked by private citizens and sporting groups.
2 - indicates fish purchased by the DNR for stocking.

Stocking Fish Sizes
Fry - Newly hatched fish that are ready to be stocked usually called "swim-ups". Walleye fry are 1/3 of an inch or around 8 mm.
Fingerling - Fingerlings are one to six months old and can range from a size of one to twelve inches depending on the species. Walleye fingerlings range from three to eight inches each fall.
Yearling - Yearling fish are at least one year old. A one-year-old fish can range from three to twenty inches depending on the species. Walleye yearlings average from six to twelve inches.
Adult - Adult fish are fish that have reached maturity. Depending on the species, maturity can be reached at two years of age. Walleye reach maturity between the ages of four and six years.

Status of the Fishery (as of 08/10/2009)

Ponto Lake (DOW # 110234) is a 347-acre lake located east of Backus, MN. A public access is located on the southeast shore just north of State Highway 84. Ponto Lake has a maximum depth of 60 feet, and 29% of the surface area is littoral (less than 15 feet). The Minnesota Department of Natural Resources (MNDNR) has classified Minnesotas lakes into 43 different classes based on physical, chemical and other characteristics. Ponto Lake is in Lake Class 23; lakes in this class are generally very clear, very deep, have a low percentage of shallow water area, and have a very irregularly shaped shoreline with many bays or points.

Walleye abundance in the 2009 sampling in Ponto Lake was similar to that found in other lakes of this ecological type. Fish from 8 to 28 inches were sampled in MNDNR test nets. Walleye naturally reproduce in Ponto Lake; however the lake is also currently stocked with walleye fingerlings. Both the number and average size of northern pike in Ponto Lake is good; sampled fish ranged from 12 to 35 inches and had an average length of 20 inches. The bluegill population is comparable to other lakes of this type, and fish up to 8.2 inches were found, however most of the bluegill are small. Black crappie from 7 to 11 inches were collected in DNR test nets. Yellow perch were scarce in the 2009 Ponto Lake sample.

The abundance of largemouth bass in Ponto Lake compared favorably with other lakes of this type, and largemouth from 6 to 18 inches were found. Other species sampled in 2009 included black bullhead, brown bullhead, yellow bullhead, bowfin (dogfish), hybrid sunfish, largemouth bass, pumpkinseed sunfish, rock bass, white sucker, and yellow bullhead.

Anglers can help maintain or improve the quality of fishing by practicing selective harvest. Selective harvest allows for the harvest of smaller fish for table fare, but encourages release of medium- to large-sized fish. Releasing these fish can help maintain balance in the fish community in Ponto Lake and provide anglers the opportunity to catch more and larger fish in the future.

Shoreline areas on the land and into the shallow water provide essential habitat for fish and wildlife that live in or near Minnesotas lakes. Overdeveloped shorelines cant support the fish, wildlife, and clean water that are associated with natural undeveloped lakes. Shoreline habitat consists of aquatic plants, woody plants and natural lake bottom soils. Plants in the water and at the waters edge provide habitat, prevent erosion and absorb excess nutrients. Shrubs, trees, and woody debris such as fallen trees or limbs provide good habitat both above and below the water and should be left in place. By leaving a buffer strip of natural vegetation along the shoreline, property owners can reduce erosion, help maintain water quality, and provide habitat and travel corridors for wildlife.
