r <br />I-15 <br /> <br />• <br /> <br />V. CONCLUSIONS <br />Based on the information presented, there is no Alluvial <br />Valley Floor at the Bourg Mine site on Mann Draw. The limit <br />of unconsolidated stream-laid deposits is shown on Figure <br />I-3. There is no evidence of historical irrigation, on Mann <br />Draw. An investigation of the vegetation on Mann Draw at the <br />Bourg site indicated that no subirrigation exists. An <br />extensive analysis of regional flood irrigation practices in <br />the Michigan and Canadian Basins indicated that such <br />irrigation could not be supported on Mann Draw. The basis for <br />this conclusion is the lack of a dependable supply of water <br />on Mann Draw. The evidence shows that the mining activities <br />., at the Bourg site will not impair future agricultural use of <br />the area. <br />Leonard Rice ConsuRing Water Engineers, InC. <br />
