. . . Cretaceous Aquifer
Cretaceous Aquifer has 20-40% porosityThe Cretaceous Aquifer consists of the Claron (40% porosity), the Straight Cliffs, and Dakota Sandstone (20-30% porosity). The beds dip to the east (see Bryce Canyon cross-section). The beds dip more to the north, as is seen looking east to or north from Fiddler's Canyon. Excellent porosity, as shown in both outcrop and rock samples shown in bottom images below. |
First well at Woods RanchThe porosity of the Cretaceous rocks is seen by the waterand ice which comes out of the rocks just above the former coal mine, and just below Woods Ranch. The saturation of these rocks is one reason for the regular landslides here. This acquifer can be tested with a well at Woods Ranch. Water from this well can be put in Coal Creek to get to Cedar Valley. Based on the successful well in the same formation at Brian Head, a Woods Ranch test is a next step. |
Second well above landslideThere are political issues about getting water rights forproducing the Woods Ranch test. The initial estimate is 4,500 acre-feet per year from this first well. This is half of the current over production in Cedar Valley. There are several other potential locations in the notes linked above. Drilling a deviated hole above the landslide and dropping it into Coal Creek allows the turbines to be placed in the deviated well bore to generate electricity, and there is no pumping cost. |
