No large bare areas or weed patches were observed at the time of inspection. <br />There were no signs of instability or erosion on the slopes. <br />o Recent rains promoted relatively good vegetation growth. <br /> <br />REVEGETATION - Rule 4.15 <br />Vegetative Cover; Timing:Reclamation <br /> <br />Fills 7, 8, and 9 were inspected.and outslopes of ponds 9, and 9A, were observed. Observations at the shrub plot <br />indicated establishment of a fraction of the shrubs planted. Weeds noted include cheat grass (Bromus tectorum), a <br />Class C noxious weed, and prickly lettuce or milk thistle, (Lactuca serriola). Clover was growing vigourously <br />and appeared to be over three feet tall. Observations at The Knob showed continued evidence of a ditch breach <br />that occurred about four years ago, (photo 7). Fill 8 shows the best revegetation success, with fills seven and nine <br />respectively, exhibiting progressively less success. <br />o The vegetative cover on fills and sediment pond slopes at the time of observation appeared healthy <br />and adequate after recent moisture with the exception of: <br />4. Instances of Elaeagnus angustifoilia (Russian olive) at pond 8 <br />https://www.colorado.gov/pacific/agconservation/russian-olive <br />and Tamarix Spp., (Tamarisk) in the shrub plot; <br />https://www.colorado.gov/pacific/agconservation/salt-cedar-tamarisk <br />(maintenance item 4, photos 9 and 10). Both weeds are Class B noxious weeds. <br />o Bare areas were observed at the west end of The Knob, (photo 8). Rills exist on the east face and <br />vegetation is establishing, albeit slowly on this face (photo 7). <br />o The area where pond sediment is deposited for drying appeared stable. <br />
