<br />Figure 3. Monthiy fiuctuations in the depth to
<br />water in weils 24 and 44 on SI. Charles Mesa
<br />(weil iocations shown in fig. 6).
<br />
<br />Why is the high water table a problem for some
<br />Mesa residents and not for others?
<br />
<br />Basement flooding can occur in one home while basements
<br />in neighboring homes may not become flooded. Several factors
<br />determine whether there may be basement flooding in a particular
<br />location on the Mesa (flg. 5):
<br />. The depth to water ranges from less than 3 feet to more than
<br />33 feet, depending on the location on the Mesa (table I).
<br />. The depth of a basement below land surface depends on the
<br />design of the house (fig. 5, basements I and 2).
<br />. Basement flooding can occur if the hOllom of a basement lies
<br />at a depth that is between the seasonally deepest and shal- .
<br />lowest depths 10 water (fig. 5, basement 2).
<br />. Pumping of nearby wells can increase the depth to water to a
<br />level that is below the bollom of a basement (flg. 5, base-
<br />ments 3 and 4).
