Since none have <br />reached the 6D6 criteria we won't be cleaning them this summer. The drainage <br />reconstruction projects you approved have reduced the sediment load into our <br />system significantly. <br />The sediment survey in Coyote Dam has just been completed. We are working up <br />the sediment cross-sections this week. The results will follow. We feel we <br />will probably have to clean a portion of Coyote this summer but do not have <br />the volume (cyds) calculated for removal. If there are any questions, please <br />call me. <br />Since%/rely, <br />K../~'Z~if~it/.. <br />H. Bruce Humphries <br />Sr. Env. Engineez <br />WSH/jb (JUN24] <br />pc R.L.
