• 2.04.7 H dv rology Information Groundwater Groundwater occurrences in areas adjacent to [he permit area are found in two different formations. Alluvial material of the North Fork of the Gunnison River contain groundwater resulting primarily from runoff and flow of the north Fork of the Gunnison River. Groundwater in very minor amounts may also be found in the formations of the Mesaverde formation. Due to its higher elevation above the North Fork of the Gunnison River and relative discontinuity of sandstone, shale, and siltstone materials, little groundwater is evident. The Regional Geology/Hydrology Map (Map 2), show no evidence of springs within the area of the loadout facility of the Mesaverde formation. Due to the nature of the Mancos shale on which the loadout facility is located, no groundwater is expected to exist in this formation. Groundwater found specifically at the • permit area will be at a depth substantially below the surface. No groundwater is found within the sequence disturbed by the site work within the unconsolidated colluvium material. Surface Water The permit area is drained primarily by the North Fork of the Gunnison River and two minor tributaries to the North Fork of the Gunnison River. No perennial or intermittent streams exist on the permit area or adjacent to the permit area. The only water available to the permit area is as rain or snow falling on the permit area. In fact, surface water supplies are so limited that production of agricultural products at the site is possible only by irrigation. The Deer Trail Ditch intersects most overland flow upstream from the permit area with the Fire Mountain Cannel intersecting the remaining overland flow. Water from the Deer Trail Ditch flows into the Fire Mountain Canal approximately four hundred feet east of the end of Deer Trail Ditch.
