INTRODUCTION

This report concerns the ability of fish-populations in the Neosho and

Marais des Cygnes rivers in Kansas to readjust to continuous stream-flow

following intermittent conditions resulting from the severest drought in

the history of the State.

The variable weather in Kansas (and in other areas of the Great Plains)

markedly affects its flora and fauna. Weaver and Albertson (1936)

reported as much as 91 per cent loss in the basal prairie vegetative

cover in Kansas near the close of the drought of the 1930's. The average

annual cost (in 1951 prices) of floods in Kansas from 1926 to 1953 was

$35,000,000. In the same period the average annual loss from the

droughts of the 1930's and 1950's was $75,000,000 (in 1951 prices),

excluding losses from wind- and soil-erosion. Thus, over a period of 28

years, the average annual flood-losses were less than one-half the

average annual drought-losses (Foley, Smrha, and Metzler, 1955:9;

Anonymous, 1958:15).

Weather conditions in Kansas from 1951 to 1957 were especially

noteworthy: 1951 produced a bumper crop of climatological events

significant to the economy of the State. Notable among these were:

Wettest year since beginning of the state-wide weather records in 1887;

highest river stages since settlement of the State on the Kansas River

and on most of its tributaries, as well as on the Marais des Cygnes and

on the Neosho and Cottonwood. The upper Arkansas and a number of smaller

streams in western Kansas also experienced unprecedented flooding

(Garrett, 1951:147). This period of damaging floods was immediately

followed by the driest five-year period on record, culminating in the

driest year in 1956 (Garrett, 1958:56). Water shortage became serious

for many communities. The Neosho River usually furnishes adequate

quantities of water for present demands, but in some years of drought

all flow ceases for several consecutive months. In 1956-'57, the city of

Chanute, on an emergency basis, recirculated treated sewage for potable

supply (Metzler _et al._, 1958). The water shortage in many communities

along the Neosho River became so serious that a joint project to pump

water from the Smoky Hill River into the upper Neosho was considered,

and preliminary investigations were made. If the drought had continued

through 1957, this program might have been vigorously promoted. Data on

stream-flow in the Neosho and Marais des Cygnes (1951-'59) are presented

in Tables 1-4.

These severe conditions provided a unique opportunity to gain insight

into the ability of several species of fish to adjust to marked changes

in their environment. For this reason, and because of a paucity of

information concerning stream-fish populations in Kansas, the study here

reported on was undertaken.
