Details similar to those _liscussed above <br />should be observed here. <br />I.~S ~ A,Ui':.F"iiATIG[d <br />Cams 2A through 5 will reguira only minimal instrus~entaticn <br />because the foundation soi.is arc not critical an3 the dam hei;hte arc <br />low. Minimal instrwnentation conoists of at leact one reference ;point <br />on the embaril~ment and one piezaneter to d^teriine tr:c piczo:~etric level <br />beneath tine dan. A s:r~ar~ of tha recoru-iendc:.' piczomet~rs an.l <br />monu,~nents is shoc~m on Table III. <br />• At Dam 1, erore critical observation during construction is <br />required. Felatively soft foundation soils and high water table will <br />require rpnitoring of the foundation ire water during cronstructicn. <br />Piezaneters 2 and s are to be included in the er.~aniknent ~rhen it <br />reaches elevation 7305. ,This is equivalent to a out 15 to 13 feet of <br />eJ~anlanent height above the din foundation. nt the titre the embankment <br />construction is at the elevation of the ~iezemetcrs, they should be <br />installed and protected from danage. Piezoc~cters are slotted pin' in <br />~:hich the static water level can be measured with a [~scote or ta:~. <br />Once these piezometers are installed, they should be read on a daily <br />basis and a remrd kept of the elevation of t5^ static crater level in <br />the tube. As the embank;nent reaches its msximuri hei•7ht, .ttfe two <br />• additional piezo~seters arx] monyments should ~ installed. <br />
