While this ycar's water supplies are <br />expected to be markedly improved over those of the last two years, volumes are consistently <br />forecast below average. The best forecasts are located from the Animas River, east to the San <br />Juan River, where most forecasts range from 80 to 90% of avcrage. Meanwhile, the lowest <br />forccasts occur along the Dolores River where volumes of only about 65% of average are <br />anticipated this ycar. <br />
