ing a resetting of signals on distant summits and because of inter mediate triangulation being necessary to get up out of the valley so as to see them. The effort has been to leave maps and records in such shape that any future engineer can pick up station points and extend or amplify the work. 10. Contour maps on a scale of 100 feet to the inch have been prepared for each one of the thirteen villages, large and small, near to or within the site of the proposed great storage reservoir.* These maps show the location of substantially every house in each village, and how near it would be approached by the water's edge with flow lines of various elevations. The purposes of these maps are to show the highest admissible elevation of flow line for the great reservoir, and to give an accurate idea of the disturbance or damage that would be caused. 11. General topographic maps on a scale of 400 feet to the inch, with contour interval of five feet, have been prepared, embracing substantially the entire territory of about fifty square miles comprised by the proposed reservoir and its margins. These sheets, of standard size, 26 x 38 inches, were pantographed down from our survey plottings made on large sheets on a scale of 100 feet to the inch. For that portion of the reservoir site lying below an elevation of 740 feet above sea, we obtained much aid in our map making from a very good set of land boundary maps with elevations, made by the Hudson River Power Company, of which maps, the president of the company, Mr. Eugene M. Ashley, kindly permitted us to make copies. Time has failed for the completion of the full topographic work. Several gaps are left in the survey around the reservoir margin in localities of little importance, or where thick woods interfered with rapid progress; but out of more than 100 miles of margin probably less than ten miles is unfinished, and a reconnoissance has been made in these gaps sufficient to show the lay of the land. 12. The volumes of the proposed Sacandaga reservoir to various proposed heights of flow line have been determined from the *Copies of these maps are inserted at page 156 reduced. |
