<br />In Ihe West, ground-water levels declined seasonaUy
<br />in North Dakota, southern California, Utah, Arizona,
<br />and New Mexico. Trends were mixed in other western
<br />States. Water levels were below average in Arizona, and
<br />mixed with respect to average in other western States.
<br />New high ground.water levels for August were recorded
<br />in Nevada and Utah, despite slight net declines during the
<br />month in the reporting key weUs. New low levels for

<br />and a new low August level was recorded in the EI Paso
<br />key well in Texas despite a net rise of less than a foot
<br />during the month. Although there was a net decline of
<br />less than a foot during the month in the Steptoe Valley
<br />observation well in Nevada, a new aU time low level
<br />occurred in 39 years of record. Another aUtime low
<br />level was reached in 41 years of record in the key well
<br />at Dayton, in Eddy County, New Mexico, in the southern
<br />part of the Roswell basin.
