..;;_ - ~~ III. COMMENTS •- COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. Hydrolooic Balance There was flow in the permanent reclaimed channel, apparently irrigation drainage water. The sediment pond contained a shallow pool of clear water, with the water level approximately 3 feet below the primary spillway outlet. Cattails and other emergent wetland vegetation species have become established in the pond area. Remaining diversion and collection ditches appeared to have functioned effectively in handling recent storm runoff, with no erosion or failures evident. Some sediment deposition was evident in flatter segments of the ditch, and maintenance would appear to be warranted,. although the ditch appears to still meet design capacity. Water appears to have ponded to near the top of the ditch at the extreme upper end (based on high water mark) , and additional grading or build-up of the berm at this .location is recommended. Backfilling and Grading Remaining reclamation work scheduled to be completed this fall includes relocation of the lower segment of the permanent reclaimed channel, elimination of the existing lower channel segment which bypasses the pond, elimination of certain remaining diversion and collection ditches, installation of cuts in the permanent channgY berm in several locations to allow upland drainage to enter the channel, ripping of the roadbed segment, and seeding of the various areas disturbed by the final reclamation work: -- Revegetation 8' Vegetation growth on reclaimed areas seeded in 198 remains green and lush due to the ample late summer precipitation this year. During walk-through of the revegetation, 11 cool season grasses, 3 warm season grasses, 3 shrub species, and 2 perennial forb species were observed. The visual dominants are the native shrub, fourwing saltbush, and the native cool season bunchgrass, bluebunch wheatgrass. The vegetation has effectively stabilized the site, with essentially no erosion apparent on the reclaimed slopes. There are scattered patches of the noxious species Russian knapweed, white top, and field bindweed, but the operator has conducted weed control efforts in compliance with Division guidelines, and the noxious species represent a very minor component of the vegetation biomass.
