Arizona's natural attractions include deserts, mountains and canyons. Although not as noticed, another important natural feature is the state's perennial streams. Segments of such rivers as the Gila, Salt, Verde, San Pedro and the Hassayampa flow year round and support fish populations, wildlife and water-based recreation as well as sustaining rich riparian ecosystems. A concern about maintaining perennial flow at some minimal level, with possible seasonal variations, is the central issue in the instream flow debate.
