<br />
<br />Notes:
<br />1. Volumes rounded to the nearest 1,000 acre-feet.
<br />2. Subregions defined in Figure 4 of SB06-193 Study. 'SP' denotes areas along mainstem of South Platte River.
<br />Subregion 16 (South Park) not included in volume calculations due to lack of data.
<br />3. Unsaturated volumes exclude the upper 10 feet; from Table 2 of SB06-193 Study. Assumes 20% porosity.
<br />4. Saturated volumes are from average water table surface to base of alluvium. Assumes 20% porosity.
<br />5. Tributaries include all subregions that do not have 'SP' in the subregion name.
<br />6. Designated Basins include Upper and Lower Lost, Kiowa and Bijou Creek subregions.
