All San JUaJl- <br />Chama diversions originate in Colorado and about 55,000 AF of that total comes <br />directly frDm the Navajo mainstem. I would also note that 47,310 AF pass the OSl)o <br />Diversion Dam which suggests that no more than 10,000 AF can come in from New <br />-it <br />Mexico between there and Edith. Adding the Edith flow to other gaged flows (San. , <br />Juan @ Pagosa - 273,000 AF + Rio Blanco below Diversion - 28,620 AF) accounts . <br />for 359,000 AF of the Carracus flow. Thus, 79% of the Carracus flow is accounted <br /> <br />J <br />
