The opening of the fishing season has local environmental authorities urging anglers to look after the environment.
This includes not lighting fires on public conservation land, reporting sightings of aquatic pests and camping only at designated areas.
Department of Conservation staff spent yesterday morning at Lakes Tarawera, Rotoiti and Okataina, making sure signs showing anglers where they could camp overnight were in tact.
Department of Conservation biodiversity ranger, Maurice Wilke, said it was especially important the public knew the areas they could camp around the lakes to lessen the impact on the environment.
Wilke expected to see many boats out on the lakes come Monday.
