<br />few months of flow records for thi s sllPp1 ementa1 source were coll ecteo in 1986
<br />and 1987. During that short perioo, the infiltration gallery provided almost
<br />28 percent of the total supply. Over an entire year, it is estimated that the
<br />gallery supplies an average of about 20 percent of the total existing Towaoc
<br />supply (Harri s, 1 987a). Based on an estimated present popul ati on of 1,330
<br />peop1 e, and assumi ng that the pumpi ng records represent 80 percent of the
<br />total supply, Towaoc usage averaged 94 gallons per capita per day (gpcd)
<br />during 1986.
