by computer triangulation methods and it was plotted by computer. The field <br />survey consisted of a minimum of 9 land-surface shots per 100 ft~. The <br />field data was stored in a total-station data collector. The physical <br />features depicted on the map are located within a 0.05 ft of actual <br />position; the altitudes of specific points were measured to within ± 0.02 ft <br />of actual (6). <br /> <br /> The depth-to-wate~ or the altitude of the water-table surface within <br />each of the temporary piezometers is plotted on figure 2; the locations of <br />the water-supply wells on the Bladholm property are shown on figure 1. <br /> <br />Vegetative Cover <br /> <br /> The proposed Site's land surface vegetative cover is of mixed grasses <br />with scattered bushes and scrub trees, mostly aspen, to 30 ft in height; <br />wetland vegetation occupies less than 0.5 acres in the northwest part of the <br />Site (fig. 2). <br /> <br />Surface Water <br /> <br /> During certain short-lived meteorological events (spring runoff, while <br />the near-land surface soils are frozen, and overland runoff from high-volume <br />rainfall), surface waters move to either the discontinuous ditch that <br />parallels the west limit of the proposed Site and the bounding ditches of <br />the Burlington Northern Railway on the south, or to topographic lows in the <br />northwest and east-central part of the Site. However, for most of the year, <br />because sandy soils underlie the Site to moderate depths (fig. 8), that part <br />of the annual precipitation that is not lost to evapotranspiration or runoff <br />(approx 10%).moves (seeps) downward to the water table -- the upper surface <br />of the zone of saturation. <br /> <br />8803 11 <br /> <br />R.K.
