Very good access to beet fish, including in the form of a stable population of cyclists, combined with a low fishing pressure has favored the growth of the predators of the lake. Sample fishing with fish and fishermen's experience has shown that there are very large individuals of both perch and pike in the lake. Since 2005, many pikes have been taken over 100 cm. In 2008 a pike of 14 kg, 125 cm was taken. Good access for those who fish by boat with loading ramp and car and trailer parking. A number of rest areas with wind / rain protection and barbecue facilities are available at different places in the lake. In Kornsjö there is a kiosk with guest dock in the summer.
Norra Kornsjön is located in Enningdalsälven's catchment area in Dals-Ed municipality in Västra Götaland County and Haldens municipality in Östfold County Norway.
