' broadleaf cattail (Typha latifolia) in some parts of this pond gives the <br />appearance of not being mined for some time. This gravel pit has irregular <br />' shorelines and indentations, indicating that reclamation procedures were either <br />not required, were not implemented, or that mining operations were simply <br />suspended. This pond is currently connected to the Colorado River mainstem. The <br />' CDPOR purchased the land around the larger gravel pit to construct a foot/bicycle <br />trail as part of the Colorado River Riverfront Project. <br />Annual row crops are currently being grown on the Van Wagner property north <br />' of the smaller pond. This property is scheduled,for construction of a mobile <br />home park. Plans are to convert the smaller pond into a recreational fishing <br />pond for residents of the mobile home park. Although there is road access to the <br />t ponds and along the drainage ditch, no public motorized vehicle access is planned <br />for either recreational area. <br />Gravel pit mining activity presently occurs immediately east and west of <br />' these ponds. Grand Junction Pipe and Supply Company is mining to the east; Elam <br />Construction, Incorporated to the west. <br />Water Management <br />' General. The Grand Junction Irrigation District has an access easement to <br />operate and maintain the drainage ditch through the property that drains directly <br />into the Colorado River. They will occasionally require vehicle access to clean <br />the drainage ditch and culverts. <br />t The water level in the large, isolated pond remains relatively constant <br />throughout the year. The water surface area in June 1993 was 7.4 acres; <br />September 1993 was 7.1 acres. Both ponds, most likely, are fed by groundwater <br />and surface return flows from irrigation ditches in the immediate area and from <br />groundwater percolating laterally from the river. This obviously helps maintain <br />' year-round water levels in both ponds. The smaller pond to the north is <br />physically separated from the larger pond by two road berms and the drainage <br />ditch. The water level in this pond fluctuates more than the larger pond <br />annually because it is connected to the river. The water surface area in June <br />' 1993 was 3.5 acres, and in September 1993 was 2.9 acres. Although water depth <br />profiles have not been taken for these two ponds, the smaller pond appears to be <br />shallower and is gradually filling with sediment at the eastern, upper end, that <br />' is farthest from its connection with the river. <br />Reclamation procedures for the larger pond are underway. A shallow-water <br />' area has been established in one portion of the pond to create a wetland. There <br />are presently no water control structures at the site. <br />One of the three major channels of the mainstem river to the south of the <br />' larger pond has recently taken a northerly course and is cutting into the dike <br />separating the pond from the river. This cutting was accelerated during the <br />spring flows of 1993. Originally, the conceptual plan was to backfill the larger <br />t pond and grade it gently back to the river, cut a channel in the dike, and <br />connect the pond with the river so that the pond would naturally fil_1 during the <br />spring runoff and drain following spring runoff.
