Hydraulic pressure in the Weber and Entrada was eventu- <br />ally dissipated locally, and the Marland Well stopped <br />flowing about 1936. Hydraulic pressure, however, main- <br />tained the flow at the lower elevation Meeker Well. <br /> <br />4. Plugging the Meeker Well in 1968 allowed pressure to <br />build up in the Entrada and Weber Formations. This <br />caused flows at the Kritsas Wells (which were later <br />plugged) and a rise in the water level in the Marland <br />Well. The Marland Well water subsequently escaped <br />through deteriorated casing and spread through the upper <br />Morrison Formation, escaping along the north bank of the <br />White River where the overburden had been eroded. <br /> <br />14 <br />
