TECHNICAL ASPECTS OF WATER MANAGEMENT
PRACTICES FOR THE PAW PAW RIVER BASIN
by Norman F. Billings*


The purpose of this papr is to explore the role of applied hydrology in
the development of water nd the regulation of water uses in the Paw Paw
Basin as exemplary of Michigan areas where consumptive and non-con-
sumptive uses are coming into competition. It considers this role both
with respect to the develop ment of legislation, in which hydrology is in-
volved chiefly from the standpoint of its general, basic principles, and
to the actual administration of water management practices, where the
science finds very detailed application.

LAW OF WATER ALLOCATION


Ground water resources may be somewhat above average for the state,
both in areal distribution and in potential yield. It is believed that very
substantial quantities are available in the glacial drift throughout much,
but not all, of the basin.

Present Water Use and Development

Soils, climate, proximity to markets and other factors in the vast com-
plex that determine resource usage have led to the development of an ag-
ricultural- industrial- recreational economy.
Agriculture is devoted, in a large degree to growing small fruits, tree
fruits, and truck and specialty crops, with a consequent somewhat unusual
adaptability to irrigation. Average annual applications of water are in the
neighborhood of 6 inches. The practice is growing steadily and rapidly,
doubling both in acreage and numbers of systems about every 3-1/2 years.
In 1954 the total area under irrigation was about 5,563 acres and the total
water use about 2,340 acre feet or 1,170 day second feet. On the other
hand, artificial drainage has been necessary to make some agricultural
lands arable.
Recreational water usage centers about the lakes, whose shores are be-
coming heavily built up with cottages and year round dwellings. Stable lake
levels are most desirable for all types of recreational use. Information is
not available as to the extent of recreational developments on streams but
such use is undoubtedly growing, both for residential and sports fishing
purposes.
Hydro-electric power is developed at one downstream site, at Water-
vliet. The degree of water use there is not known but in Michigan generally
hydro-electric power plants use all medium and low flows.
Industries and municipalities, mostly on the lower reaches of the river,
use the Paw Paw for waste disposal. Their combined waste loading results
in pollution of the river to the extent that it is injurious to the public health,
lawful enterprise or fish and aquatic life during periods of low stream
flow. The pollution is accordingly unlawful and is being reduced under
orders of the Water Resources Commission. Those orders must be reas-
onable and cannot require that the reduction of waste loading be carried
any farther than is necessary to abate existing injury. However, if the low
stream flow on which pollution control orders are based is depleted, the
waste loadings, eVen though reduced, may again cause injury and therefore
be unlawful and subject to further Commission orders.
The Paw Paw thus contains all the types of water conditions, water and
land relationships, and water use problems that are found in the state. Be-
cause each river basin has its own physical and economic individuality, the
degree of those conditions, relationships and problems varies from basin
to basin. Those variations do not imply the need for different laws or ad-
ministrative practices in the various basins. The need, instead, is for flex-
ibility and responsiveness to needs whenever and wherever they occur.

hydrologist in actual administration of water rights law. Now, instead of deal-
ing with general principles he must occupy himself with very specific facts.

Establishing Minimum Stream Flows and Lake Levels

The law will provide in some way for the protection of time-honored
rights-of that we can be certain. The first job in water management in
the Paw Paw Basin, then, will be to identify and evaluate those rights in
exact terms-cubic feet per second, acre-inches, hundredths of feet in
water level elevation. This will be necessary even though the rights in
question may never before have been recognized with such exactitude, in
order that additional needs may be filled to the greatest possible extent.
It is to be hoped that the law will at least say how such determinations
shall be made. That can be done as in the new Mississippi law, which
calls for the use of past stream-discharge records in computing or esti-
mating minimum flows to be reserved for non-consumptive uses. But
because some streams even at low flow carry much more water than is
needed for any present use, the law should also provide an alternate
basis for deciding how much the flow of such streams might safely be
depleted.
Possibly that alternate could be expressed in the law as a rate of
stream flow per unit of drainage area, as, for example, ".4 cfs/sq.mi."
In that case; as with the past-record approach, the hydrologist's work is
mainly collecting and analyzing a great deal of stream-flow data. If, how-
ever, the law only relates the propriety of diversions to limits which are
set by the needs of fish life, then the hydrologist together with the fish
habitat authority have a very difficult job. The writer's understanding,
from Michigan fisheries authorities, is that only research and experience
will show how much water is required under the various possible condi-
tions, to sustain fish life on this stream or that.
The problem of ascertaining minimum lake level conditions that are
compatible with existing rights and needs is appreciably simpler than the
identification of minimum acceptable stream flow. Michigan has consid-
erable experience under statutory law in the establishment of "normal"
levels, which are reasonably susceptible of determination with respect to
the record of past levels, to existing development of shore properties, and
to fish spawning conditions.

Regulation of Diversions

After minimum stream flow rates and lake level elevations have been set,
the administrative functions come into full play with the allocation of prior-
ities to consumptive uses and the regulation of those uses with respect to
each other and to minimum flow or levels. Hydrologic activity requisite for

516 LAW OF WATER ALLOCATION

Ground Water Problems

The Paw Paw Basin, like many other irrigable areas in Michigan, of-
fers substantial potentialities for obtaining water from the ground. Except
as ground water supplies are permanently depleted, their production is
largely at the expense of stream flow. Where pumping lowers the water
table beyond reach of phreatophytes, evapo-transpiration losses will be
reduced. Significant water savings may result in some cases. However,
widespread and heavy pumping is bound to cause some reduction in stream
flow and lake levels. The effect will not be as drastic as from direct sur-
face water diversions, but will tend to be spread over weeks or months.
It will be least at the beginning of the irrigation season and will increase
as the season progresses.
Pumping tests will be useful in estimating the degree of diminution in
flow or lake levels which may result from ground water production. Such
tests are laborious, expensive, and require highly skilled technicians for
their interpretation. We would look for them to be employed in the devel-
opment of general guides to ground water management rather than on a
wholesale basis.
It is difficult at present to visualize the criteria which might be selected
as bases for regulating ground water pumping. It seems unavoidable that
production from the ground must enjoy a favorable position in relation to
direct diversions from surface water. When streams and lakes reach base
conditions, the enforced cessation of diversions therefrom will at once
terminate their effects. But ordering a well shut off at that time, half a
mile distant from a stream, will produce no observable response at all
in the stream. Shutting off a hundred wells might cause some improvement
in stream flow after a period of weeks, but the critical conditions may well
have been ended by then. Unless a benefit is produced, we can see no point
in requiring the cessation of pumpage. If wells are to be allowed at all,
they might as well be allowed to operate continuously. A more logical ap-
proach might lie in limiting the total allowable monthly pumping from
wells within the drainage basin. But every well's pumpage reduces stream
flow to some degree and thereby aggravates the conditions which we seek
to prevent in reserving base flows from direct diversion. No benefit would
result from reserving a greater flow in an attempt to anticipate and ac-
commodate the effects of ground water pumping. The effect of diversions
on a surface stream can be terminated very quickly by stopping the diver-
sion. The effect on stream flow of pumping from the ground, on the other
hand, will persist long after the pumping is stopped. But who can forecast
stream flow conditions with sufficient accuracy to substantiate, in court,
the need for shutting off wells weeks ahead of time ?
