In addition to the above, small contour furrows in and above the erosion area may be constructed <br />to trap and slow down the runoff. Straw dikes will also be used where appropriate to control <br />runoff and promote revegetation. <br />Other Methods If corrective measures described under the discussion for No Defined Channel <br />fail, WFC proposes to observe and reevaluate the situation. A combination of the first two <br />methods described or some variation therein will be applied. Methods such as, but not limited to <br />rock channels, contour furrows or laterals with rock or matting bottoms, V ditches made with the <br />dozer or motor grader, and methods described above to reestablish vegetation. <br />Head Cutting Stabilization Head cutting will be controlled by a number of methods. If the <br />area is at a point that concentrates runoff, the area will be improved to accept this runoff. This <br />would include reshaping the channel and channel bottom, covering with erosion matting, <br />seeding, or rocking. <br />In other areas, depending on the extent of erosion and time of year, the area will be disked, <br />mulched and seeded as needed. Straw bales, erosion matting, or rock fill may also be used to <br />stabilize the area. <br />Weed Management and Pest Control Plan - All Areas <br />A number of designated noxious weeds listed as either on the Colorado Department of <br />Agriculture's List A or B have been identified as occurring in either the West End of Montrose <br />County or adjacent San Miguel County. Known List A species which occur in this area include: <br />Cypress Spurge (Euphorbia cyparissias), Purple Loosestrife (Lythrum salicaria), and Yellow <br />Starthistle (Centaurea solstitialis). During the vegetation surveys conducted on this site in 2009, <br />Purple Loosestrife was observed as occurring at several locations within the wetland areas of <br />Meehan Draw. <br />Known List B species which occur in this area include: Absinth Wormwood (Artemisia <br />absinthium), Black Henbane (Hyoscyamus niger), Canada Thistle (Cirsium arvense)* Chinese <br />Clematis (Clematis orientalis), Corn Chamomile (Anthemis arvensis), Dalmatian Toadflax <br />(Linaria damlatica genistifolia), Diffuse Knapweed (Centaurea diffusa), Hoary Cress (Cardaria <br />draba)*, Houndstongue (Cynoglossum officinale)*, Leafy Spurge (Euphorbia esula), Mayweed <br />Chamomile (Anthemis cotula), Musk Thistle (Carduus nutans)*, Oxeye Daisy (Chrysanthemum <br />leucanthemum), Russian Knapweed (Acroptilon repens)*, Russian Olive (Elaeagnus <br />angustifolia)*, Salt Cedar (Tamarix chinensis, T. parviflora, T. ramosissima)*, Scentless <br />Chamomile (Matricaria perforata), Spotted Knapweed (Centaurea maculosa)*, Sulfur Cinquefoil <br />(Potentilla recta), and Yellow Toadflax (Linaria vulgaris). Of these 20 List B species, a total of <br />eight, were observed during the vegetation studies performed in 2009 on this site. These species <br />are marked in this list. <br />Section 2.05.4(2)(e) Page 28 May 2015 <br />
