III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations <br />made during the inspection. Comments also describe any enforcement actions taken during <br />the inspection and the facts or evidence supporting the enforcement action. <br />02228 -Stable channel reach with large riprap, short distance upstream of Stock Pond T-18. On the <br />steepest riprapped segmentjust above Pond T-18, Grade = 18%, BW 7', TW 12'. Grade is within <br />design range and capacity exceeds design for the grade. <br />02229 <br />02230 -Canada thistle infestation on 005 Gulch sideslope upstream from Stockpond T-18. <br />02231 -View upstream on 005 Gulch, from point a short distance upstream of Stockpond T-18. <br />02232 -Lower reach of 005 Gulch Segment MM/LL, between Stockpond T-18 and Ridgeline Access <br />Road. Segment appears to be within design grade range, properly riprapped with large, well placed <br />angular rock. Trapezoidal shape with 10' TW, 3' BW, and depth greater than 1 foot (exceeds design <br />capacity for grade). <br />02233 -Lower reach of 005 Gulch Segment MM/LL; Ridgeline Access Road culvert and adjacent <br />sections of channel. Ditch construction as described for previous photo. Road culvert partially <br />obstructed and requires maintenance. <br />02224 - 005 Gulch Segment LUK, downstream of 005-E1 confluence and upstream of Stockpond T-20 <br />Minor erosion along edge of riprap in a couple locations, but channel segment generally appears stable, <br />with adequate capacity. Vegetation is becoming established through the riprap. The steepest segment <br />of the reach was measured at 21%, which exceeds the maximum design grade of 12%. <br />006-NE4 Gulch Channel <br />02234 <br />02235 -Low gradient upper segment (less than 10%). Resembles atwo-track road due to riprap <br />haulage. The design specifies a "V" channel, 1.2 feet deep. Actual channel is approximately 12 feet <br />wide, with average depth of 4" or less. Flow has concentrated in wheel ruts, which are developing rills <br />Minimal vegetation establishment. Low gradient reaches lower on the channel are similar. Channel <br />shape does not conform with design. <br />02236 <br />02237 -Upper steep segment (17% slope). Road-like appearance with rills up to a foot deep <br />developing in wheel ruts in some locations. Channel averages 12 to 14 feet wide, with average depth <br />less than 6 inches. Channel shape does not conform with design. <br />006-NEi Gulch Channel <br />02238 <br />02239 -Overly wide, flat, shallow segments along much of the upper reach (PP - JJ), with insufficient <br />riprap along channel sides in deeper sections; rills along sides of riprap and on channel side slopes. <br />02240 <br />02241 <br />02243 <br />02244 -Steep reach upstream from oil well road culvert (upper segment of JJ -BB). Channel scoured <br />in some locations, with underliner exposed and damaged. sideslope armoring generally lacking. <br />Maximum gradient 21 % (design max. is 20%}. Channel riprap needs to be extended to the road culvert <br />inlet. Also, the road ditch down-drain at the culvert inlet location has eroded and needs to be riprapped. <br />4 <br />
