T, <br />Reporting Period August 4, 1997 -August 1 1, 1997, <br />4 <br />Pore pressure data is being collected from the three electrical piezometers installed into the <br />foundation soils under the F-walls (main embankment) on August 3. With approximately 10' of <br />embankment in place, no rise in pore pressure has been observed in the easternmost or <br />westernmost piezometers. In the center piezometer (VW-2), a slight drop in pore pressure was <br />detected on August 11. Monitoring of these piezometers will continue. Inclinometers 1-9 at the <br />north toe of the embankment was installed today (August 11). Installation of Inclinometer I-10 at <br />the south toe of the embankment is scheduled for August 17. A location sketch for these <br />instruments is attached. <br />If you have any questions or concerns, please fee] free to contact me at (970) 929-2207. <br />Sincerely, <br />~~ W ~ ~~~ <br />Eric W.
