WATER-TABLE FLUCTUATIONS IN THE SPOKANE VALLEY 

AND CONTIGUOUS AREA, WASHINGTON-IDAPO

BY ARTHUR M. PIPER AND GEORGE A. LA ROCQUE, JR.

ABSTRACT

The report describes certain ground-water features of the valley p^ing along 

the Spokane and Little Spokane Rivers in Washington and of Rathdrum Prairie 

and contiguous extensive plains that extend northeastward to Lake P^nd Oreille 

and the Pend Oreille River, in Bonner and Kootenai Counties, Idaho. Together 

these plains cover about 425 square miles. They are largely undrained.

These plains aie formed by outwash and some other deposits of glacial origin, 

which are at least 500 feet thick at many places and which are in large part 

extremely pervious to water. These deposits contain a large body of unconfined 

water, which presumably is derived from deep infiltration of rain and melted snow 

on the plains, percolation from certain of the lakes along the margins of the plains, 

and percolation from numerous creeks that discharge onto the plains. The catchment area extends into Idaho, far beyond the drainage basin of the Spol'ane River; 

and only a minor part of the ground water is derived from that stream. From 

this catchment area the ground water converges toward the head of tl 3 Spokane 

Valley and then passes westward as underflow to and beyond Spokane. The 

amount of this underflow is very large, on the average about 1,000 cnbic feet a 

second or 650,000,000 gallons a day.

In the part of the Spokane Valley that is in Washington, ground water is 

withdrawn for public and industiial supplies and for irrigating about 8,000 acres 

of land. For all these purposes the average rate of withdrawal is estimated to be 

about 100 cubic feet a second or about 65,000,000 gallons a day. .Also, in the 

vicinity of Spokane, a considerable part of the underflow is discharged naturally 

from numerous springs along the Spokane and Little Spokane Rivers. This discharge supplies a major part of the water that flows in the two streams in late 

summer and autumn and that is then available to operate hydroelectric generators 

at and below Spokane.

The movement of ground water, just described, is controlled largely by the 

configuration of the bedrock surface on which the outwash was depos'ted. This 

surface is essentially the trunk valley of a preglacial stream, which apparently 

drained the basin of the present Clark Fork of the Columbia River westward 

through the present Pend Oreille Lake and Spokane Valley. Thus, the underflow 

through the outwash is a segment of the regional drainage system 1 nt crosses 

the divide between two principal streams of the present time.

The report includes and interprets in a preliminary fashion about 12,000 measurements of water level in wells in the period ending with 1938. For the years 

piior to 1938, most of these measurements were made by non-Federal agencies 

and were made available to the Geological Survey through the Water Division of 

the city of Spokane and the Washington Water Power Co. These data on groundwater levels are unique for the Pacific Northwest in that they afford continuous 

records covering 10 years or more for many of the observation wells.

LOCATION AND EXTENT OF THE AREA

The region covered by this report includes about 125 square miles 

in Spokane County, Wash., in Tps. 25 and 26 N., Us. 42 to 46 E., and 

about 300 square miles in Bonner and Kootenai Counties, Idaho, in 

Tps. 50 to 57 N., Rs. 2 to 6 W. (See fig. 4.) In Washington it includes 

the valley plains along the Spokane and Little Spokane Rivers; in 

Idaho it includes Eathdrum Prairie and contiguous extensive plains 

that extend northward from the Spokane River to the Peid Oreille 

River. , 

NATURE AND SCOPE OF THE REPORT

This report comprises data on fluctuations of water level in observation wells that are widely spaced over the several plains. (See pi. 4.) 

These data were gathered in connection with an investigation that was 

begun late in 1937 through cooperation between the Geological Survey, 

United States Department of the Interior, and the Washington State 

Department of Conservation and Development. This investigation is 

intended ultimately to establish approximately the safe ground-water 

yield of the Spokane Valley in Washington. The data (pp. 93-137) are 

unique for the Pacific Northwest in that they afford continuous records 

covering a period of 10 years or more for many of the wells, also in that 

they show the behavior of a large ground-water body that is r,n integral 

-part of the regional drainage system.

Most of the water-level measurements were made initially by nonFederal agencies and have been made available to the Geological 

Survey by the Water Division, city of Spokane, and by the Washington Water Power Co. Beginning in January 1938, water-level measurements have been made periodically by the Geological Survey at 

25 observation wells.

The pertinent surface and geologic features of the area, the drainage 

system of streams and lakes, and the functional relation of tl e groundwater body to the surface drainage system are described to afford an 

adequate background for a preliminary analysis of these water-level 

data.

LAND FORMS AND OEOLOOIC FEATURED'

The Spokane Valley, with whose ground-water resources this report 

is primarily concerned, is commonly understood to include tl °, lowland 

plain along the Spokane River for a distance of about 20 miles eastward from Spokane to and a few miles beyond the Washington-Idaho 

boundary line. This plain is from 2 to 6% miles wide. It is about 

1,900 feet above sea level at Spokane, but it rises uniformly eastward 

about 10 feet to the mile to an altitude of about 2,100 feet above sea 

level at the interstate boundary. Still farther east the plrin widens 

into Rathdrum Prairie, which, with contiguous lowland plains, is 6 to
86 CONTRIBUTIONS TO HYDROLOGY OF UNITED STATES, 1941-43

17 miles wide and extends northeastward to the southern arm of Pend 

Oreille Lake. Tongues of the plain extend even farther northward, to 

the Peiid Oreille Kiver. In altitude these plains range from 2,100 to 

2,500 feet above sea level. Certain plains or "prairies" are extensive 

terraces, bounded by a scarp or scarps as much as 200 feet high.

Near Spokane the lowland plains just described abut sharply against 

the Columbia Plateau and several of its outliers, such as Fivemile 

Prairie and Pleasant Prairie. These remnants of the Columbia Plateau 

are 300 to 400 ft et above the Spokane Valley. Farthe"" east the plains 

abut against siroothly contoured mountain slopes with a local relief 

as great as 3,70(1 feet.

The Spokane Valley, Kathdrum Prairie, and the contiguous plains 

are underlain by incoherent or loosely coherent gravel and sand, at 

many places at least 500 feet thick. These deposits are largely the 

outwash from glaciers that once occupied parts of the area, apparently 

in two distinct epochs. According to Bretz, 1 in the earlier or Spokane 

epoch of glacial ion, ice advanced from the north, crossed Fivemile 

and Pleasant Prairies, and at maximum extent reached and extended 

about 15 miles beyond the site of Spokane. In the later epoch, probably the Wisconsin stage of glaciation, ice advanced from the northeast, 

covered all the site of Kathdrum Prairie, and extended eastward about 

to Spokane. During recession, the front of this glacier stood for a 

considerable time in the southern arm of Pend Oreille Lake. From 

this front there was transported much of the great voHme of outwash 

that forms the terraced lowland plains in Idaho and the plain of the 

Spokane Valley in Washington.

In the bedrock surface over which the outwash we.s spread, rivers 

and glacier had cut valleys with floors several hundred feet beneath 

the present lowland plains. In Idaho these older valleys had a pattern 

somewhat different from that of the present streams.2 To the west, 

the bedrock valley that underlies the Spokane Valley plain probably 

was occupied by a master stream that drained an area far more extensive than that drained by the present Spokane River. The outwash 

buried all this pre-Wisconsin rock surface under a thick mantle that 

built up the lowland plains to their present altitude? and doubtless 

obliterated some drainage divides of the bedrock surface.

Beneath the Spokane Valley a very large part of the glacial outwash 

is composed wholly of cobbles and pebbles, which rerder it very pervious. High perviousness is also indicated by the extraordinarily 

large specific capacities of wells that enter the outwash, commonly 

1,000 gallons or more a minute for each foot of draw-down. Being 

several hundred feet thick and at least 2 miles across, the whole tongue

of outwash has an extraordinarily large capacity to transmit ground 

water. > >

The floor beneath the outwash is composed of rocks smh as form 

the mountains and plateau outliers that enclose the plains. Thus, 

except near Spokane, that floor is composed almost entirely of the 

crystalline and metamorphic rocks that are described briefly by Pardee 

and Bryan3 as the "granite-schist group." These rocks are essentially 

impervious. At and near Spokane the floor probably is formed in part 

by the rocks that underlie the outliers of the Columbia Plateau sedimentary and volcanic rocks of Tertiary age. These rocks, whicfc are 

described at length by Pardee and Bryan,4 are only moderately ori 

slightly pervious,

In summary, the Spokane Valley and contiguous lowlanc1 plains are 

underlain, commonly at a depth of several hundred feet, by an impervious rock floor part of a pre-Wisconsin valley system th^t presumably discharged westward by way of the Spokane Valley. T 9 pattern 

of the pre-Wisconsin valleys is not known precisely, but apparently 

the Spokane Valley trough received the drainage from ar extensive 

area to the east and northeast, an area much more extensive than that 

now drained by the Spokane River. The pre-Wisconsin valleys are 

filled to a depth of several hundred feet by glacial outwash that has an 

extraordinarily large capacity to transmit ground water. Thus, the 

pervious £01 affords an integrated system of conduits through which 

ground-water drainage can converge from an extensive intake area it( 

Idaho toward the head of the Spokane Valley and thence pass westward to and beyond Spokane.

LAKES AND STREAMS

The most striking elements in the drainage system o* the area 

probably are the numerous lakes that occupy depressions along the 

margins of the outwash plains. These include Liberty and Newman 

Lakes in Washington and Coeur d'Alene, Pend Oreille, Spirit an4 

other lakes in Idaho. They are random in altitude. All are fed by 

perennial streams that drain adjacent mountainous terrain, but only 

the largest two, Pend Oreille and Coeur d'Alene Lakes, have outlet 

streams. Pend Oreille Lake receives the runoff from an extensive 

rugged terrain by way of the Clark Fork and discharger into the 

Pend Oreille River, which formerly was also known as the Clark 

Fork; this outlet stream passes a few miles north of the area covered in * 

this report. Coeur d'Alene Lake is fed largely by the St. Joe and 

Coeur d'Alene Rivers. Its outlet, the Spokane River, skirts the south

margin of Rathdrum Prairie, continues westward to Spokane, and 

thence courses northwestward to the Columbia River.

For most of the distance between Coeur d'Alene Lake and Spokane, 

the Spokane River occupies a shallow and somewhat sinuous trench in 

the outwash plain. In the heart of Spokane, this trench is superposed 

on a sheet of "valley basalt," over which the river plunges in spectacular falls. Here the floor of the pre-Wisconsin bedrock valley presumably lies a mile or two farther north. Below its falls the river 

flows in a deep gorge-like but terraced valley commonly known as the 

gorge or "lower valley" of the Spokane River.5 The relation of the 

river to the regional water table is described later.

All the mountainous terrain that encloses the outwash plains is 

thoroughly drained by numerous perennial creeks. A considerable 

number of these drain into the lakes that have no outlet streams. The 

others have no definite channels across the outwash plain and, with one 

exception, do not flow perennially into the Spokane Eiver above the 

falls. This exceptional creek drains a relatively small area in the 

vicinity of Post Falls, where the river flows along the very edge of the 

outwash plain.

GROUND WATER BENEATH THE OTJTWASH PLAINS 

SOURCE, OCCURRENCE, AND MOVEMENT

The large body of ground water that exists in the outwash gravel 

presumably has been derived from the three sources indicated below 

and is intermittently or perennially replenished from them: Deep infiltration of rain and melted snow from the many extersive undrained 

tracts on the outwash plains; percolation from some of or all the 

numerous lakes, both those that have outlet streams and those that 

do not; and percolation from the numerous creeks, both intermittent 

and perennial, that reach the outwash plain but do not cross it. The 

proportionate volumes of water derived from these several sources is 

not shown by data now available. Apparently, little or no ground 

water is derived permanently from the Spokane River below the Post 

Falls gaging station.

In the northern part of the area, near Athol, Idaho, a body 

or possibly several bodies of perched water apparently exist in the 

outwash. This locality is only a few miles west of the terminal 

moraine that closes the southern arm of Pend Oreille Lake; thus it is 

not unlikely that downward percolation is there impeded by a sheet 

or lentil of impervious till. Possibly other bodies of perched water 

exist. Otherwise, however, the outwash appears to contain but one 

mam body of ground water that is nowhere confined.

From water-level data now available it is inferred that the regional 

water table beneath Rathdrum Prairie and the eortiguous plains

 Pardee, J. T., and Bryan, Kirk, op. cit., p. 3.
SDPOKANE VAiOLEY, WASHENGTON-IDAHO. , , ,-,,',, 8$,

farther north is trough-shaped, with flanks that slope downward iroi% t 

both margins of the outwash plains. The bottom of the inferred: 

trough is rather deep, nearly 500 feet beneath the highest terrace of; 

the outwash plain west of Athol (well 53/4W-24D1) 6 and about 2QQ 

feet near the interstate boundary (well 51/5W-33D1). Northeast-, 

ward, up the hydraulic gradient, the bottom of the trough seems to be 

a prolongation of the water surface in the south arm of Peid Oreille 

Lake. If the flanks of the trough rise to and prolong the r^ater surfaces of other lakes those flanks must slope rather steeply.

Westward from the interstate boundary the troughlike form of the 

water table presumably continues, though the slope of either flank 

must be rather gentle. Also, the depth of the water table below the i 

land surface decreases steadily; at well 25/43-14K1, near the east 

boundary of Spokane, the depth is about 48 feet. ;

The water in the glacial outwash presumably moves radially southwestward from the extensive catchment area in Idaho to tie head of 

the Spokane Valley and thence generally westward toward Spokane.r 

In detail, the direction of movement probably is controlled to a large 

extent by the configuration of the buried rock surface. Because the 

water table seems to be a prolongation of the south arm of Pend 

Oreille Lake, it is inferred tentatively that the trunk valley on the 

buried rock surface and the main thread of ground-water movement 

extends from that arm of the lake to the head of the Spokane Valley 

and thence to and beyond Spokane. It is conceivable, but by no 

means definitely established, that a tributary thread of ground-water 

movement trends southward from the Pend Oreille River beneath 

Hoodoo Valley. As explained in the next section of this report, the 

aggregate rate of westward movement beneath the Spokane Valley is 

at tunes more than 1,000 second-feet, or 650,000,000 gallon? a day.

INTAKE AND DISCHARGE WITH RESPECT TO THE SPOKANE AND 

LITTLE SPOKANE RIVERS

With respect to replenishment of the main body of grounc1 water in 

the outwash gravel and discharge from it, the Spokane River may be 

divided into two reaches, an upstream reach that extends from the 

head of the river at Coeur d'Alene Lake to a point 4 miles west of the 

interstate boundary and a downstream reach that extends a few miles 

beyond Spokane. Along the upstream reach, at least below Fost Falls, 

the river appears to be insulated and higher than the regional water 

table. Its bed must be essentially watertight, for ordinarily the flow 

neither increases nor decreases appreciably along the reach, as shown 

by numerous stream-discharge measurements made by the Geological , 

Survey and the Washington Water Power Co. During freshets the 

river may lose some water by downward percolation beyond the edges

of its watertight bed; however, this possible loss is toe small to have 

been conclusively shown by stream-discharge measurements. At the 

lower or western end of this reach the grade of the river intersects the 

regional water table. Along the downstream reach th^ river flows in 

a valley cutting the water table. There its bed is rot everywhere 

watertight, for at low stage numerous springs are exposed along its 

banks. Thus, this lower reach of the river gains by ground-water 

discharge, except possibly during freshets. In the aggregate this discharge is considerable; during the late summer and autumn the river 

commonly gains from 600 to 800 second-feet above the falls at 

Spokane, as indicated by gaging-station records.

The lower reach of the Little Spokane River is aralogous to the 

downstream reach of the main river, just described. That stream 

likewise gains commonly by ground-water discharge from numerous 

springs; an aggregate gain of a few hundred second-feet is estimated 

from miscellaneous discharge measurements by the Washington 

Water Power Co. in 1931-32.

Altogether, this natural ground-water discharge in the lower parts 

of the Spokane and Little Spokane Valleys appears commonly to 

have been as much or more than 1,000 second-feet during the late 

summer and autumn. This discharge into the streams contributes 

a large fraction of the water that is used for the generation of hydroelectric energy at Spokane and farther downstream.

WITHDRAWAL FROM WELLS

In the Spokane Valley, within Washington, ground water is withdrawn from wells for public supplies at Spokane and several suburban 

communities, for numerous industrial plants, and for irrigating about 

8,000 acres of land. The withdrawal for all these purposes may well 

amount to 75,000 acre-feet a year or at the average rate of about 100 

second-feet, or about 65,000,000 gallons a day. The maximum rate 

of withdrawal is estimated to be about 250 second-feet.

WATER-LEVEL FLUCTUATIONS

As indicated on plate 5, the ground-water level ri the outwash 

gravel has fluctuated through a moderately wide range over the entire 

area, commonly from 5 to nearly 20 feet each year. In certain parts 

of the area in particular the higher terraced plains in Idaho, the 

margins of the plain along the Little Spokane River, and probably 

other districts the ground-water level has also tended to rise or 

decline progressively for periods of several years duration. Because 

the ground water is unconfined, these fluctuations represent commensurate replenishment and depletion of ground-water storage. Each 

foot of rise or fall of the water level indicates replenishment or deple-
VALLEY, WASHINGTON-ID AftQ * ,- ;- 01 f

tion, respectively, amounting to about 50,000 acre-feet ir the area 

between the south arm of Pend Oreille Lake and the falls at Spokane* 

The fluctuations also indicate a moderately large yearly range in the 

hydraulic gradient along the Spokane Valley. Because tfy<* outwash 

gravel is so highly pervious, this range in gradient indicates an appre- - 

ciable yearly fluctuation in the rate of underflow to the areas of ground- - , 

water discharge near Spokane. . ' /;

The yearly range of ground-water level appears to be greatest and 

the high ground-water stage of the year appears to OCCTI^ earliest . ,1 

near the Spokane River in the area of ground-water discharge (pi. 5, 

well 25/43-11K1). There the water level commonly is low and fairly 

steady through the summer and autumn, fluctuates moderately 

during the winter and early spring, rises sharply to a maximum stage 

in April or May, and then declines to a low stage by July or Augus.fc. 

The hydrographs in plate 6 show that these fluctuations of groundwater level are similar to fluctuations of stage in the Spokane Eiviej* 

and that they are primarily a backwater effect of fluctuating river 

stage. Only intermittently does the river rise so rapidly or stand - 

at a high stage so long that the water-table gradient is reversed arid 

slopes downward from the river. Thus, only for relatively brief . '- 

periods is ground-water discharge checked, even with vater-level 

fluctuations so large. . >"'

Eastward, beyond the area of discharge, the water table attains its,, v , : 

highest level progressively later. Beneath the higher terraced plains 

in Idaho the highest level occurs ordinarily in July or August (pi. 5, 

well 53/4W-24D1). This eastward lag in the yearly rise of the water 

table is inferred to be in part a delayed backwater effect of fluctuations 

in the area of discharge and in part an effect of late infiltration on the 

higher plains and late runoff to the northern lakes. Owing to the lag, 

the hydraulic gradient between the higher plains in Idaho and the l 

area of ground-water discharge near Spokane tends to b°, least in 

April or May and greatest in July or August. This gradient deteiv \ 

mines the rate of underflow to and westward along the Spoka ne Valley. " .- Thus, underflow would tend to be greatest in midsummer, to ctecline 

gradually but not greatly through autumn and whiter, ard then in _ - 

spring and early summer to diminish sharply to the year's minimum " < 

but to increase quite as sharply to the year's maximum.

Northward from the area of discharge (pi. 5, well 26/43-34P1) the 

yearly rise of the water table lags in similar fashion, but only slightly. 

There the water table is lower than at Spokane, so that replenishment 

of ground-water storage probably is accomplished largely by the 

regional underflow. The slight lag is the travel time for a replenishing^ , , 

ground-water wave that is set up by the rise of water level at Spokane; > ,' 

indirectly, therefore, this lag also is a backwater effect of f 'ictuating ! 

river stage. ' , ' ',., ,*-.
92 CONTRIBUTIONS TO HYDROLOGY OF UNITED STATEF 1941-43

At a distance from the area of ground-water discharge near Spokane, 

there was marked cumulative depletion of ground-water storage in the 

3-year period 1929-31; replenishment in 1932-34, due only in part to 

the record freshet of December 1933; and another per.'od of depletion 

in 1935-37. A period of cumulative replenishment appears to have 

begun again with 1938. These periods of cumulative depletion and 

replenishment have influenced ground-water storage in and near the 

discharge area only slightly (pi. 5, well 25/43-11K1). There the low 

water-table stage of the year is fixed by river stage, which ranges little 

from year to year during the summer periods of low f ow.

Plate 7 comprises hydrographs for two public-supply wells at 

Spokane, which together show water-level fluctuations almost continuously for the 30-year period ending with 1938. These wells are 

in the area of ground-water discharge. Only minor fluctuations of 

their water levels are caused by pumping, so that ths hydrographs 

show fairly well the long-term trend in water-table level. They suggest cumulative replenishment of ground-water storage during the 

5-year period 1913-17, cumulative though not steady depletion from 

1918 through 1924, and marked replenishment hi 1926 and 1927. 

During these periods the range of water-table level in outlying parts 

of the area may well have surpassed the range that is shown by plate 5, 

which covers only the last decade.

GROUND-WATER LEVELS IN OBSERVATION WELLS

The report includes and interprets in a preliminary fashion about 

12,000 measurements of water level in wells in the period ending with 

1938. As has been stated, most of the following data on ground-water 

level have been contributed by non-Federal agencies. The scope of 

the data collected by the several agencies is as follows: (1) Water 

Division, city of Spokane, water-level measurements at seven wells 

beginning as early as 1908; (2) Washington Water Power Co., measurements at six wells in November 1920 and continuously since 1928, 

at eight additional wells continuously since 1928, and at four wells 

"beginning in 1930 or subsequently; (3) Great Northern Railway Co., 

through the Washington Water Power Co., measurements at its Hillyards shop well, beginning in 1928; and (4) Modern Electric Water 

Co., also through the Washington Water Power Co., measurements 

at two wells discontinuously from 1912 to 1929.
