Oh, yeah. Even “natural” materials pollute the water by adding excess nutrients. As organic matter decomposes under water, it uses oxygen that fish and other water creatures need to survive.
Keep grass clippings, leaves and litter away from streams and ditches. In addition to polluting the water, yard debris that washes into storm drains and culverts may cause flooding. Compost yard debris and kitchen scraps, leaves, grass clippings and other yard wastes into organic fertilizer. For details, go to
