The lakes are located in the Lagan water system.
Nejsjön is the highest and has no major tributaries. After that comes Åbrunnen which is a small body of water before Yasjön which is the largest of the lakes. There is mainly forest around the lakes except for some open land with buildings. Ya- and Nejsjön are accessible by car and both have ramps for mooring boats. Åbrunnen can only be reached on foot. Perch and pike are the fish species you mainly encounter, but there are also roach, bream and tench.
