The physical characteristics in hydrology are the concerning to the river basin, network of drainage and to the main channel. The study was developed in the River basin Stream the India-Lake Doves that are located towards the south-east end of the state of Chihuahua (27° 22' 27" N, 105° 11' 36" W, 103° 39' 47" E, 25° 34' 43" S) and to the north of the state of Durango; according to INEGI (1992) the surface of this basin is shared between the states of Durango, Coahuila and Chihuahua. For Form, one calculated the relation of circularity, coefficient of elongation and form factor. As far as the drainage system, it obtained the type of drainage; pending average of the main channel; time of concentration, order of the currents, drainage density. In form, 0.13 were obtained, and its elongation was 0.41, extended with a length of the main channel of 319.9 km. The density was of 0.2722 km/km2 being the river basin poorly drained. The pending average of the channel was of 0.33 percent. The six order was and its average texture, indicating a slight surface run-off and permeability of the average ground. The type of drainage is dentritic. The time of concentration was 2,910 minutes. The average volume in the river basin is of 1, 705.4 million m3 and 145, 542 a maximum cost of m3/s with a period of return to 25 years the modified rational method. With the formulas Lowry and Creager, of the surrounding methods it was of 14, 620 and 14, 355 m3/s. With the simplified method of the tracks principles the maximum cost appeared in Point 3 of the site the La Vega with 55,89 m3/s.
