EXHIBIT 38 - Continued. and above the water table, which is probably the capillary fringe. The only location which exhibits increasing soil moisture within the root zone is Sudduth Draw. The root zone in Sudduth Draw is much deeper than in the other draws, and while the roots do not reach the water table, they do extend into the capillary fringe. The logs of soil moisture in the Canadian and Illinois Rivers were more erratic, due to differing lithologies and high water levels in each location. Generally, the logs show a rapid increase in soil moisture from a foot below the surface to the water table, except in Canadian River No. 1, which displays almost no moisture above the water table. The lithology of the alluvium in Canadian River No. 1 is entirely gravel, which has very little retention capacity. Therefore, the capillary fringe at Canadian River No. 1 probably extends only a few inches above the water table, and not into the root zone. The capillary fringe in Illinois River No. 1 extends upward from the water table at 3.0 feet to 1.5 feet below the surface. In summary, the capillary fringe in the intermittent drainages of Bolton, Bush and Williams Draw does not extend upward into the root zone, and the data indicate that these areas are not subirrigated. The root zone in Sudduth Draw is much deeper, and the capillary fringe extends into the root zone above the water table. A series of stock ponds along this reach of Sudduth Draw has caused the water table to remain high throughout the year, supplying artificial subirrigation to vegetation at that location. The capillary fringe in the Canadian River alluvium extends from the water table upward into the root zone, within a foot of the surface, except in one location due to alluvial material consisting of gravel. The capillary fringe in the Illinois River al- luvium extends well into the root zone. The Canadian and Illinois River floodplains have sufficient soil moisture to sustain plant growth by • flood irrigation through the summer months into September.
