Lake Langavatn is in the land of the farm Sölvabakki, about 8 km away from Blönduós. It is 55 m above sea level and has an area of 0.16 km². Langavatn was thought to be fishless, but since 1994 trout have been stocked into the lake with good results. Initial stocking was with both brown trout and rainbow trout, but in recent years only brown trout have been released under the direction of the fish-biologist Bjarni Jónsson. In Langavatn nice fish up to 5llbs can be caught, although most fish are about 3 pounds. As with many other lakes, the best fishing is in the spring, soon after the ice melts. However, it is possible to get good fishing later in the summer, when fly fishing is the best choice for anglers as the growth of vegetation inhibits the use of other baits.
