Citation: Gottfried, G.J. and DeBano, L.F. 1990. Streamflow and water quality responses to preharvest prescribed burning in an undisturbed ponderosa pine watershed. In: Krammes, J.S., technical coordinator; Effects of fire management of southwestern natural resources: proceedings of the symposium; Tucson, AZ. USDA Forest Service, General Technical Report RM-191.
Subject: fire, water quality
Vegetation type: Ponderosa Pine
Location: Castle Creek, eastern Arizona
Abstract: Mean annual streamflow for the 6 years following burning did not increase significantly over pretreatment levels. Water quality changes were evaluated by comparing pre-fire and post-fire levels of nitrate-nitrogen, ammonium-nitrogen, phosphates, calcium, magnesium, sodium, and potassium. Fire significantly changed the concentrations of some nutrients in stream water, but the changes were too small to adversely affect water quality.
