<br />For the purposes of this discussion, the wens shown in figure 4 are referred to as wen 1 (SC02405503AAC),
<br />.
<br />wen 2 (SC02405415DCC), well 3 (SC0230542IBCC), wen 4 (SC02305428CCBl), and well 5
<br />
<br />(SC02305430DBD). Information concerning the period of record and the number of measurements for each of
<br />
<br />these five wens is listed in table 3 and indicates that all five wens have been measured for much of the study period
<br />
<br />(about 1960 to 1997) and that an except well 5 have been measured more than 100 times; wellS has only been
<br />
<br />measured 36 times.
<br />
<br />Wens 1 and 4 are located near the Arkansas River and the other three wells are eitheJ'C1~se to the Fort Lyon

<br />
<br />Although the upland wells tend to generally general increase in water levels, they all also have a period,
<br />
<br />from about 1967 to about 1979, during which they had a fairly steady decrease. The decrease is most apparent in
