the river comes from a vast azea of exposed Mancos Shale in the watershed and the irrigation canals <br />providing new contacts for water with the shale. It is expected that the water quality of the pumped <br />water for the 3-4 yeazs that this operation will exist will be approximately the same as that of the <br />river itself. <br />Past surface imgation of the site has produced runoff which either directly enters either the River, <br />the small depression or the existing pond on the site. An incised man-made ditch called the <br />Farnsworth Collection Ditch begins neaz the southeast corner of the permit area at a spring for which <br />the Farnsworth's have adjudicated water rights. This spring flows water yeaz round and the water <br />currently is delivered to the small pond neaz the southwest comer of the permit azea. An overflow <br />from this pond returns the water to the ditch downstream, which enters the river shortly thereafter. <br />See Map B-1. An existing small irrigation return immediately south of the Farnsworth Collection <br />Ditch gathers any irrigation water from the orchazd to the south, thus effectively isolating the site <br />from runoff entering from the south. <br />The disturbed bench from the Farnsworth #2 Gravel Pit is located immediately adjacent to the site to <br />the east. This bench is mostly flat and devoid of vegetation. No runoff enters the new 110 area from <br />this site. A small ditch is also located on the west boundary, neaz the existing fence, which prevents <br />runoff from entering the site from the west. <br />A full wetland study is being conducted in June of 2004. It is expected that this study will reveal that <br />wetlands exist in the depression shown on Map B-1 as well as along the river banks. Other wetlands <br />exist in the ditch to the south of the property but these will not be affected by the operation. A 404 <br />permit will be applied for with the Corps of Engineer's office in Grand Junction, once the results of <br />the wetland study are obtained. This permit will cover the temporary removal of the wetlands in the <br />depression area and the low water crossing across the river. In any case, the wetlands to be restored <br />as part of the reclamation process will far exceed the amount temporarily disturbed, in size and func- <br />tion and value. <br />North Fork Pit Mazch 04 <br />
