• virtually unchanged in 2 inclinometers. Ten <br />inclinometers were dry. <br />Two wells, B-32 and SOM-13 showed anomalous water level <br />fluctuations. From early January 1982 to early March <br />1982 water levels dropped about 8 feet in well B-32. <br />This well is completed in the Barren Member <br />approximately 900 feet from the portal construction <br />area. However, the same well showed a 12 ft. drop in <br />water level during the month of June, 1981 prior to the <br />start of construction at Mt. Gunnison. Water levels in <br />Well SOM-13 dropped approximately 50 feet from the <br />beginning of August through the end of September 1981. <br />• •~1.
