<br />Warner Point Dam <br /> <br />No investigation has been done at the Warner Point Dam site; therefore, the <br />proposed program is designed to gain a general understanding of the founda- <br />tion and adequacy of construction materials, and to enable a determination <br />of the feasibility of the rollcrete dam proposed in the study. <br /> <br />Drilling - Six holes, approximately 200 feet deep, will be drilled along the <br />centerline, two on each abutment and two in the river bottom, to determine <br />depth and nature of bedrock. Borehole water pressure tests will be conducted <br />at appropriate intervals to provide information on foundation permeability. <br /> <br />Backhoe - A sufficient number of test pits will be opened with a backhoe to <br />prove out adequate quantities of COncrete aggregate in the river bottom. <br /> <br />Seismic Refraction - A survey will be made of the river bottom and left abut- <br />ment which, when correlated with borings, will enable construction of top of <br />bedrock contours. <br /> <br />Materials Testing - Gravel samples obtained from test pits will be tested <br />for adequacy as concrete aggregate. <br /> <br />Surveying and Engineering - Same as for Avery. <br /> <br />3 <br />
