MALAMA KAHAWAI: The islands of Maui County are home to many beautiful streams whose waters provide nourishment for residents and the islands’ natural habitats. Maui’s streamwaters flow through gulches, near residential areas, and down toward the sea.
Neglected stream beds filled with pollution, overgrown vegetation, and other debris can have harmful effects on native animals and plants as well as residential areas in times of flooding.
