The Wasserburg power plant and the Wasserburg power plant power train are equipped with a fish bypass. Gravel spawning grounds in the tailwater of the Wasserburg stage have been ecologically enhanced in recent years, some old water systems redesigned and reactivated.
Together with the Rosenheim and Wasserburg district fishing association, VERBUND undertook land restoration measures around the Rosenheim and Wasserburg reservoirs. These activities make a big contribution to conserving and improving the varied and biodiverse “Inn ecosystem”. The shallow water zones in the dammed area are under conservation and were declared “Vogelfreistätte Innstausee bei Attel und Freiham” (Bird Sanctuaries Inn Reservoir at Attel and Freiham) by the Bavarian state government in 1982. The protected area begins 600 metres to the south of the dam stage and extends as far as the bridge at Griesstätt. The protected area encompasses 562 hectares of river and sedimentation areas, floodplain forest and steep forested banks.
