In calculating usablf> wAter from streamflow, alluwanccA must
be made for low flow periods. The water than can be extracted con-
tinuously through these low flow periods is expressed as "yield"
over s period of time consideration; a common base is 50 years.

Maximum yield ususlly becomes an academic figure as the costs
of providing storage sufficient for maxlmumyielB become impractical
with resulting compromise construction; however, maximum yield
figures are useful in determining the total water resources. The
maximum yield of streams leaving the Newton-Jasper County area ex-
ceeds 500,000,000 gallons per day.23 Water use, by six selected
purposes, are shown on Table 4.

Water quality in the Newton-Jasper County area is generally
good, but waste dispossl'in this area of Missouri represents a
sizeable problem. Several large municipalities and industries
discharge waste in headwater areas with practically no benefit
of dilution. The streams of this area are highly valued aesthet-
ically and receive much recreational use. Any waste discharges
to streams of this nature should be of high quality if these
values and uses are to be maintained. Industrial waste is 8
major component of the total waste load entering some municipal
facilities. In some cases, industrial waste comprise the largest
portion of the city's discharge.24 Table 5 shows miles of streams
and degree of pollution, according to the Missouri Department of
Conservation.

Residential area pollution problems are increasing in non-
public sewer areas of concentrated housing, many of which have
inadequate individual disposal systems with resultant soil sat-
uation and ponding. Bacterial pollution of shallow groundwater
in these areas will be of lessened concern with the provision of
public water supplies, chiefly through the growth of rural water
districts. The entry of waste discharges into underground aqui-
fers has been found to be another major problem in this area.

Most sewage facilities, of smaller cities in the area, are
oxidation lagoons. This type of treatment is the most economical
for a smsll community and has been shown to provide, a suitsble
,degree of treatment when properly designed, operated and maintsined.'
Most of the srea has safe"potable groundwater, but there is no
comprehensive program of testing individual wells; many of which
are of sub-standard construction and can be contaminated by surface
waters.25 '

The mid-size and larger municipalities in the area provide
mechanic,~ treatment, generally in the form of trickling filter
plants. In several mechanical plant installations, a polish-
ing lagoon is used before final discharge. Ail of the mechanical
