All outfalls have been properly maintained <br />and no ponds exceeded the 60% threshold for sediment accumulation except for one structure, No -Name #2 that is <br />currently at 70% of its sediment capacity. This structure will be cleaned this summer. <br />P.O. Box 187 Craig, Colorado 81626 (970) 824 -4401 <br />
