-A REPORT UPON THE FISHES OF IOWA, BASED UPON OBSERVATIONS AND COLLECTIONS MADE DURING

1889, 1890,

AND

1891.

BY SETH EUGENE MEEK.

INTRODUCTION.

InAugust,1881,Dr.

David

S.Jordan,

now

ofPaloAlto, California,accompanied

by

thewriter,

made

a collection of fishes inthe southern partof

Iowa

intheinterest oftheIT.S.Fish

Commission and

theU.S.National

Museum.

This

was

practically thefirst steptaken toward acomprehensive studyof theichthyological features of Iowa.

The work was

not,however,

resumed

until1889,when, under the direction of theU.S.Fish Commissioner, thewriter

began

an exhaustive examinationofallthe streams

and

lakeswithin the bordersoftheState. Thisinvestigation

was

continued untilJuly, 1891,

and

the present paperisbased

upon

thecollections

and

observations

made

duringthatperiodofabout

two and

a half years.

Intheconductof

my

field

work

I

have

been placedunder

many

obligations toMr.

C.J.Ives,presidentofthe Burlington,

Cedar Rapids and

NorthernRailroad,

and

to Mr.Joseph White, superintendentofthe water supply ofthe

same

corporation, for specialfacilitiesinthe

way

oftransportation

and

for otherfavors,

which have

enabled

me

toextend

my

studies

beyond

thelimitof

means

at

my

disposal. Valuableassist- ancehasbeenreceived from Prof.R. E.Call,of

Des

Moines; from Prof.Osborn,of

Ames, and

fromProf. C. C.Nutting,of

Iowa

City,

who have

alsoobtainedfor

me

the privilegeofexaminingthe collections of fishesbelongingtotherespective institutions withwhich theyare connected. I

am

also greatlyindebtedto Mr.B. F.

Shaw,

for- merlyStatefishcommissioner,

and

toDr.

DavidS.

Jordan andProf. Charles H.Gilbert, the latterespecially for theirkind assistance in regardtotheidentificationofrare anddifficultspecies. Prof.Percy B. Burnett,of Lincoln,Nebraska,

and my

students, Mr.

W.

T.Jackson

and

Mr.E. P.Boynton,

have

renderedefficientservices inconnec- tionwith thefieldexpeditions, the firstmentioned having accompanied

me

during

much

ofthe

summer

of 1890.

of erosionthey never extendfar

back

from theMississippi River.

The

surface rises gradually,however,from the southern

and

easternborders

toward

thenorthern

and

western,theleastelevationabove theseabeing about 450feet,

and

thegreatestabout 1,500feet.

Iowa

isnear thecenter ofthe best agricultural portionofthe country,

and

thesoil,

which

isfrom1 to2feetthickon the uplands,

becomes

very

much

deeper inthedepressions

and

bottomlands. Thissoilconsists of finely

comminuted

material, generallystrewnwith scatteredbowldersor rock fragments.

Most

ofthe State is

undulatingor rollingprairie.

Rone

ofitssurfaceisheavilytimbered,

and

thegreater partofthe timber land

which

does occurisconfined tothe bordersofthestreams.

The

prairie

was

originallycoveredwith a dense

growth

of prairiegrass

and

her- baceousplants,

which

tended to produce astiffsod.

During heavy

rains this sod absorbed thewater,preventingitsdirectflow intotherivers,

and

itreached thelatter chiefly

by

slowlyfilteringthrough thesoil.

The

streams

were

thusrelievedfromover- flow,

and were

keptfrom drying

up

during thesummers. Ihave been informedthat

many

streams,formerlydeep

and

narrow,

and abounding

in pickerel, bass,

and

cat- fishes,

have

since

grown wide and

shallow,while the

volume

ofwaterin

them

varies greatly inthedifferentseasons,

and

theyare

now

inhabited only

by

bullheads, suck- ers,

and

a few minnows.

The

breakingofthe nativesodforagriculturalpurposes has especially affectedthesmallerstreamsin thisrespect,while theconstruction of ditches

and

thepracticeofunderdraining

have had

theireffects

upon

thelarger ones. More- over the constant looseningofthesoil,infarming,tendstoreduceittothat condition in

which

itisreadilytransported

by

the

heavy

rains toproduce

muddy

currents.

To

thiscause,no doubt,is

due

the presentabsenceof troutfrom

many

ofthestreamsof northeastern

Iowa and

their

marked

decreaseinotherpartsoftheState.

The

rain fallin

Iowa

isnot verygreat and,asitoccurschiefly inthe spring,even the larger rivers

become

reducedin

volume

during theremainderoftheyear

much beyond

the apparent capacityof their basins. Thereare, however,in thenorthern

and

eastern partsofthe State

many

large

and

beautiful springs,

some

of

which

arecapable of maintaining considerable streamsofwater during theentire year. Spring Branch, near Manchester,in

which

trout are

common, and McCloud Run,

near

Cedar

Rapids, are fed

by

springs of this character.

A

hatchery

was

built,afew yearsago, at the spring givingriseto

McCloud Run, and many

trout

were

hatched

and

plantedthere.

Thisstationhasrecentlybeen abandoned, but a fewtroutarestilltobe foundinthe clear,coldwater.

Iowa

issituated

between two

ofthelargest rivers of the continent,being

bounded

on theeast

by

theMississippi,

and

on thewest,exceptatthenorthwesterncorner,

by

theMissouri. It isdrained

by many

smaller rivers

which empty

into these

main

arteries,forming

two

generalsystems,thewatersof

which

flownearlyatrightangles toeachother.

Those

tributary totheMississippi trend, ina general way,southeasterly

;

and

those tributary to the Missouri,southwesterly.

The

northern

boundary

ofthe Stateliesnear thewatershed

between

thetributariesoftheMinnesota River

and

the streams

which

drain Iowa.

Most

oftheriversof this State, therefore,

have

theirorigin withinitsborders,afew,however,risinginsouthern Minnesota; and, except alimited

number whose

sourcesare inthe southern partoftheState,allterminate withinits limits.

The

affluentsoftheMississippidrain alittle

more

thantwo-thirds ofthe area oftheState;

among them

areitslargest

and most

importantrivers.

Tliestreamsofsouthwestern

Iowa have

usuallyvery

muddy

bottoms, whilethose elsewhere,having stronger currents, are generally characterized

by

sandy,gravelly, orrockybottoms.

The

formeraretheleastadaptedto fish life

and

arenotrich in either species or individuals; with thelatterthecontraryistherule.

Therearewithin thelimitsofthe State a fewlakes ofmoderatesize; these are situatedonornear

some

watershed

and

eachisfed

by

only afew smallstreams.

The

most important are Clear,Storm,Spirit,

and

Okobojis Lakes. Clear

Lake

is very shallow

;

Storm and

Spirit

Lakes

are successively

somewhat

deeper,while Okobojis

is

by

farthedeepestof

them

all.

Allofthe

more

importantrivers

have

oneormore,sometimes

many, dams

across them;

and

few,ifany, oftheseare supplied withfishways.

As

arule,the

dams

are not firmly constructed,

and

every spring

many

are

washed

away, neverto berebuilt.

During the springof1890

much

injury

was

donetothe

dams

inthe northeastern part of the State,

where

thesestructures are

more common

thanelsewhere,butin1891the regionabout

Cherokee

suffered

most

in thisrespect.

At many

places

where dams

existthestreams

widen

outabove them, forming shallowlakes.

These

areascontain

much swamp

vegetation,

and seem

to

have become

fairlystockedwithbass, pickerel, andsunfishes.

The same

fishes, I

am

told,

have

increased in

abundance

in such localitiessincethe

dams

werebuilt.

All ofthestreams

examined by

thewriter,exceptperhapsafewinthe southwestern part oftheState,werewellsupplied withthe smallerfishes.

With

respect,however, tothe

abundance

ofthelargerforms,it

was

oftendifficultto reachsatisfactory con- clusions

by

theuseofthe ordinarycollecting seines. In the

bayous

along thelarger streams

young

blackbass, pickerel,

and

various species ofsunfishes were always foundinlargenumbers. Mi. B.F.

Shaw,

atone timefishcommissionerofIowa, did veryeffective

work

duringhisoccupancyofthatofficeinseiningthefishesoutof

many

ofthese bayous,

where

agreatmortality occurs annually,

and

depositing

them

in the lakes

and

rivers.

He was

thefirsttosuggest

and

putintopractice thisefficient

method

oftransplanting

and

preserving the nativespecies,but the

work was

notcon- tinuedsubsequently,asitshould

have

been.

Much would

be gained

by

againresort- ing to thiseconomical systemofpropagation,theutilityof

which

hasbeensufficiently demonstratedinIllinois

and

other adjacent States.

There

isat present,however, a growinginterest

among

certain

game

ofallkinds

and

of assistingintheprotection

and

increaseofour nativefood-fishes.

As

aresult of observations,it

was

found that thetemperatureofthecoldest springs intheState

was

about 48°F.

; butinfew streams

was

thewater temperature below 60°F. In nearlyallsuchcasesthe range

was

from 70°to75°F.,butitshould betaken into consideration that these observations

were

chiefly confined to the

warmer

months.

I.—

THE

MISSISSIPPI

RIVER.

Collectionswere

made

in this river at Muscatine

and

Davenport, the former locality affording

by

far the best results. Thereare

many bayous

atMuscatine,and therivertherehasgenerally asandy

bottom and many

islands.

The

bestfish

market

in

Iowa

isalso located inthatcity.

At Davenport

there arefewer bayous,

and

the

bottom

oftheriveris

more muddy and

rocky.

One day was

spentatDavenport,and threedays,at differenttimes, atMuscatine.

Mad Creek

isa smallstream flowing through Muscatine

and emptying

intotheMississippi.

Few

specimenswere observed except nearits mouth.

The

species

enumerated

inthefollowinglistarefrom the riveratMuscatineunlessotherwise expresslystated.

IV.—

THE IOWA RIVER.

The Iowa

Eiverrises inthenorth-centralpartoftheState.

The

country nearits source is a slightlyundulatingprairie,

becoming more and more

broken towardits mouth.

The

river

was

visited atGarner,Belmond,

Amana, and Iowa

City.

At

Gar- nerthewater

was

confined toafewholes,ratherdistantfrom oneanother, in

which

grass

was

so

abundant

thatit

was

quiteimpossibletoseine.

We

succeeded,however, intaking a few bullheads(A.melas)

and

the

mud minnow

(U.limi).

The

greatscarcity ofwater

was due

toaprolonged seasonofdry weather,

and was

an unusualoccur- rence.

The

streamat thispoint

was

notbordered

by

timber.

At Belmond

theriverisfrom 20 to40feetwide.

A dam

at thisplacebacks the waterfor

some

distanceabove.

We

collectedbelow thedam,

where

the

bottom was

gravelly

and

sandy. Thereis

much

vegetationintheriverashort distancebelow the

dam and

a

weak growth

oftimber alongitsbanks.

The

water

was

clear,the current rather slack,

and

theriverunusuallyslow.

When

the mill

was

in operation there was butlittlewater flowing over the

dam.

Pickerel

seemed

quite plentiful inthe grass,but only a few were caughtinournets. Smallfishes

were

abundant,especially justbelow the dam.

The

temperature on July 29

was

73° F.

At Amana

the riveris

much

larger than at

Belmond.

Aquatic vegetationis veryscarce

and

the

bottom

sandy. Thereis not

much

timber along the banks.

A

smallcreek emptiesintotheriver at this point,

and when we

were there the waterin thecreek

was

confined toa fewholes.

From

these holes large pickerel

were

taken,

and

also

many

crappies,P.annularis

and

P. sparoides.

At

the

mouth

of the creek thewater

was

from 4 to7 feet deep,

and

the

bottom muddy. The

examinationat

Amana was made September

11.

The

temperatureisabout the

same

asinthe

Cedar

RiveratWaverly.

At Iowa

City theriver has about the

same

characteristicsas at

Amana.

Itis

somewhat

larger

and

deeper,

and

in

some

placesisbordered

by

ratherlowcliffs. There

is also

more

timber along its borders.

A

small creek with a very

muddy

bottom nearits

mouth

flows into therivernear

Iowa

City. Collections

were made

inthe river

and

inthe creek

by

Prof. C. C.Nutting

and

thewriter inOctober,1889. I

was

informed

by

a fishermanthat in former years the largercatfishes,pickerel, buffalo, and basswere very

common

in theriver,

and

that fishing forthe

markets

inthe spring

was

thenquite lucrative. Theselarger fishes arestilltaken,butin

much

less numbers.

Through

thekindnessof Prof.NuttingI

have

beenable to

examine

thecollection offishesfromthe

Iowa

River in the

museum

ofthe

Iowa

StateUniversity,

and

the additional factsgained thereby

have

beenutilizedinthepreparation ofthefollowing list.

V.-THE CEDAR RIVER AND

ITS

TRIBUTARIES.

The Cedar

River basin properly forms a partofthe

Iowa

Riverbasin,but

owing

to thefactthatabove the junctionofthe

two

riversthe

Cedar

Riveris

much

thelarger stream,itseems besttotreatthelatterseparately.

The Cedar

isthesecondlargest river inthe State

and

oneofthe

most

picturesque.

Together withits northerntributariesit risesin southern Minnesota. Its general courseissoutheastas far as

Moscow,

about15milesfrom theMississippi River,

where

itturnsalmost at rightangles and, flowing southwest only about 30miles,empties intothe

Iowa

River.

The

currentofthe

Cedar

Riveris swifterthan thatof either the

Des Moines

orthe Iowa. Its

bottom

forthe

most

partissandy,especiallyabove

Moscow,

butthere are occasional stretches of

mud and some

rockypatches.

The Cedar

basinisan undulatingprairie,with considerable timber along both the

main

river

and

itstributaries. Thereare also

many bayous and

small

ponds which

areconnectedwith the river at ti

m

es ofhighwater. In thelarger bayous,

where

thereis

much swamp

vegetation, pickerel

and

variousspecies of sunfishes abound.

The

largest

bayou

isnear

Cedar

Rapids.

On

the

maps

itisusuallydesignatedasCedar Lake,butlocallyitis

known

astheSlough.” Itisaboutthree-fourths ofamilewide

and

2 miles long,

and

isfastfilling

up

atpresent. It isconnected with theriver at alltimesoftheyear,containsan

abundance

ofvegetation,

and abounds

withsunfishes

and

bullheads.

Some

black bass

and

pickerel

and many

mudfish are alsotaken from itswaters.

The Slough

is decidedlythefishing-

ground

for the smallboysofCedar Rapids,

and

I

have

oftenseen

them

homeward

tripwithstrings ofbullheads

and

sunfishesaboutaslongastheaverage

At

Austin,Minnesota, theriverislittle

more

thana large creek.

The bottom

is mostly sandy,but there are occasional stretches ofdeep water with

muddy

bottom.

Aquatic vegetationisscarce

and

At

the timeofourvisitthe

volume

ofwater

had

been

much

reduced

by

dry weather. Its temperatureonJuly25,1890,

was

71°F. TurtleRiverisatributary ofthe

Cedar and

and

its

bottom

mostly

muddy;

it isfed

by

large

marshes and

shallowlakes.

Rose

Creek,anothersmall tributarynear Austin,is fed

by

springs, has a veryrocky bottom

and

a swift current; pickerel

seemed

especially

abundant

init; itstemperatureon July25,1890,

was

69°F.

The Cedar

Riverat

Waverly

is very

much

largerthanatAustin; its

banks

are bordered witharather

heavy growth

oftimber; itsbottom is very sandy,

and

its waterclear; itstemperatureon July 31

was

74°F.

The

Shellrock Riverisnot

much

smallerthan the

Cedar

aboveitsjunctionwith the latter,

which

it

much

resemblesexcept thatits

banks

are less heavilytimbered. Its temperatureon July 31

was

74°F. Fishes

were

aboutas

abundant

as inthe

Cedar

River.

Near Waverly

thereare

some

large springs.

Cedar

River,

where

thewater

was

at thisplace holds the waterback over adistance ofabout5 miles,therebyincreasingthewidthoftheriver.

Thisenlarged partcontains

many

islands

and much

aquaticvegetation.

Below

the dam,foraboutone-third ofamile,the currentisveryswift

down

it

sandy. Thereisconsiderabletimberin thisregion.

PrairieCreekisawesterntributaryofthe Cedar, a small stream borderedinthe lowerpartwithtimber. Its

bottom

isusually

muddy,

withoccasional stretches of sand. Mr. AquillaMiller,

who

has residedonits

banks many

years,informed

me

that the larger fisheswere formerlyquite

abundant

init,butat present onlysmallones can befound.

IndianCreekisaneastern tributary, smallerthanPrairieCreek,with a sandyor rocky bottom,

and

is bordered

by

timber.

A much

greater

number

of fishes

was

foundinIndianCreek thanin Prairie.

At Mount Vernon

thebottomofthe

Cedar

Riverissandy. Cliffs,calledthePali- sades,about60 feet high, occur on the westernside.

A

few small streamsflow into the rivernearthisplace.

At West

Liberty the current

was more

moderate than at the other placesvisited,but thegeneral characteristics ofthe riverwere the same.

Most

ofthecollection

was

obtainedfrombayous near theriver,but a few specimens were taken from a small creek

between West

and

theriver.

Itwould hean easy mattertodestroy large quantities of theselampreysinthe spring,if itwere thoughtexpedient, inviewoftheinjurywhich theyaresupposedtoinflictupon someofthe food-fishes. They undoubtedly do somedestruction,buthow muchit isdifficultto say. I havecomparedthelampreysfrom Cedar Rapids with specimens fromIthaca,

New

York,and regard thespeciesfrom bothlocalitiesas identical.
