The fish population in Hog Lake is comprised of northern pike, yellow perch and white sucker. The lake has a history of supporting a high population of small size northern pike. The 1994 survey again found high numbers of northern pike, with fish up to 28.5 inches observed, however northern pike over 22.0 inches are uncommon. Average size was only 17.5 inches for northern pike. The poor quality (size) of northern pike is related to the scarcity of yellow perch for forage. The small size of yellow perch (6 inch average) also leaves them undesirable to anglers.
