<br />EXPLANATION
<br />
<br />Figure 2. Generalized skew coefficients of the logarithms of annual maximum streamflow for Colorado and
<br />adjacent States (from Interagency Advisory Committee on Water Data, 1982).
<br />
<br />Separate regression equations for estimating
<br />!load magnitude were developed for each of these five
<br />regions. The five hydrologic regions used in the study
<br />area (fig. 1) are referred to as the mountain region.
<br />Rio Grande region, southwest region, northwest
<br />region, and the plains region. The mountain region
<br />':Dnsists of the high topographic relief of the Rocky
<br />Mountains north of the Continental Divide and north
<br />
<br />of the Rio Grande drainage basin to the Colorado-
<br />Wyoming border and is defined by the 7,500-fl
<br />elevation contour along the eastern and western
<br />slopes of the Rocky Mountains. The Rio Grande
<br />region includes all the Rio Grande drainage basin.
<br />the San Juan Mountains east of the Continental
<br />Divide, the San Luis Valley, and the Sangre de Cristo
<br />Mountains, which includes a part of the headwaters
