The location of a dam, on the <br />160 acre property that will be mined in the neaz future, was located subject to a field <br />check. The water impoundment and pipeline will be a future concern. Will continue <br />survey work this year before and after the irrigation season. Consideration of a once a <br />year survey after the irrigation season. This will require a more frequent walk through the <br />property. <br />Cracks were reviewed and the southeastern set might be filled this summer. <br />The mine staff will locate the impoundment on a map. <br />April monitoring readings did not indicate a significant loss of elevation and no impact <br />on the Crawford residence. <br />Having Maness & Associates take over the monitoring was discussed. Ernie Maness <br />would be agreeable if I would be available on a limited basis. Ernie and I discussed the <br />need for an up to date base map and what would be the most appropriate map. <br />The missing survey point TBM SB #2 was located, for future reference-the cap is <br />between a metal utility box and a angular brown boulder a distance between the points is <br />31 feet and the cap is 18.5 feet from the comer of the utility box. Caps should be replaced <br />by cleaning out a small area around the casing for the cap to fit on the casing. Tom really <br />found the casing. <br />Sincerely, <br />v/'/,~. <br />~-~~ <br />Harry L. Siebert, Consultant <br />cc: Mazc and Julie Crawford <br />
