Preface

The primary purpose of this study is to ass~ble and evaluate vater records

that are in the files of the T:-uckee-Carson Irrigation District, Fallon, .

These are the same records that the 3ureau of Reclamation has used in its opera-

tional a.'1d routing studies in connection with the proposed 'i-lashoe Project.

Tabulations and summaries of these records will be included in this report to

support conclusions reached. Basically, this study is designed to determine the

relation of the proposed 1-!ashoe Project and the Stillva.ter Wildlife Management

D:l 1958 the Kational Coneress in Washington created a Cccmission titled,

"Outdoor Recreation. Reserves Review Commission". I quote from their report to ·' Congress in 1962: "i-later is e. focal point in outdoor recreation".

1. P.istorical Water-use Practices of Ne"Wlands Project

To determine the va.ter use pra.ct ices on the !~e"Wl.a:ld.s Project, records of

the supply, diversion, and distribution, of vater for the entire period of

record--eenerally 41 yee.rs--.....ere used. Certain basic conclusions used by the

Bureau of Reclamation on this will be pointed out ~~ere the results of this

study differ from Reclamation's assumptions.

The evaporation and seepage loss figures used by the Bureau of Reclamation

in its Washoe Project studies are open to q_uestion. The Reclamation Bureau has

used a constant figure--a yearly figure--while actually the seepage and evapora-

tion loss in lAhontan ReserYoir and the Truckee Canal ve.ry frot:l year to yee.r,

depending on certain factors that affect evaporation--vater temperature, ambient

air ter.rperature, latent beat of the vater, vater depth, vind movement and surface

e.rea. ... OOtJ14o 2

A study vas published in the Journal of the Irrigation and Drainage Division, ------=-Proceedings --of ---the American Society --of Civil Engineers, "Evaporation From Pyramid e.nd \-.'inne::1ucca Lakes, Nevada.", by S. T. Eard.ing and E. P. Osgood, dated March,

1962. This study is the result of a long period of observation by the authors.

Conditions of this study are comparable to conditions in the still.... -ater lo.'ildlife

Management Area, both as to elevation, climate, and temperature. The result of

this study vould indicate that the methods used by the Bureau of Reclamation in

determining evaporation on Lahontan Re2ervoir and the Truckee Canal should be

carefully revieved.

s. T. f~ding vas hired by the Truckee-Carson Irrigation District to evalu-

ate the Washoe Project and its effect on the Truckee-carson Irrigation District.

Eis r-eport is dated January 15, 1960. I quote directly from this report, Page 6:

"LOSSES IN IAH011TAN RESERVOIR

''Storage in Lahontan is subject to evaporation loss and percolation. water

absorbed as the reservoir rises may return to the reservoir as it lovers. Some

of the vater vhich percolates from storage becomes leakage and does not return

to storage. Records of evaporation have been secured from observation of an

evaporation pan at the reservoir. Ccnpariaons of inflov, outflow, evaporation,

and change of storage on hand have been used to co."npute the monthly percolation

losses or bains that have occurred under the historical operations. These

results were used to derive a relationship betveen the percolation and the

other it~~ ~bich affect its amount.

"The most recent of such results are those of the Bureau of Reclamation.

In their 1951 report on the Nevlands Project, the Bureau derived relationships

for the reservoir losses at lahontan for both rising and falling stages. These

were used to estimate the losses that vould occur under future operations when

70,000 acres vere irrigated by the Truckee-carson Irrigation District. 000147 3

"For the 34-year period 1916-17 to 1949-50 the Bureau found a mean annual evaporation of 32,500 acre-feet and a mean annual net percolation loss of 32,200 acre-feet. These itens totaling 64,700 acre-feet are in addition to the estimated

delivery demand of 424,100 acre-feet used by the Bureau for the irrigation of

70,000 acres in the Truckee-Carson Irrigation District."

As indicated by the records, in certain years it has been necessary to 15pill vater excess to irrigation needs at . Such water has gone to the

stillwater Wildlife l'/.a.nagement Area and Carson I.ake Pasture (Greenhead. Club), and bas contributed largely to the creation ot the marsh and the l!lB.iDtenance of the present developments. The Hs.shoe Project proposes to capture the l!l8.jor portion of these spills iD Hatasheamu Reservoir. This vill destroy a substantial part of the •-ater supply \.rhich was fo:r-.nerly contributing to the Stillwater \-.'ildli:fe

Management Area.

The 'Washoe Project is largely subsidized· by pover and flood control. The flood control regimen vould be established by the Corps of Engineers of the u. s.

Arr:Iy. Long experience has shown that these tvo interests are often inimical to irrigation interests and can, and often do, waste water that could be used for irrigation on farmland.s B.!ld marsh areas.

2. Prospective Water-use Practices of Newla.nds Project under Washoe Project

Figures taken from Bureau of Recl.em.ation reports and some other reports dealing with future water use on the Newl.ands Project have been B.!lalyzed to determine how these conditions will effect the vater supply of tbe stillwater

Wildli:fe Management Area.

In 1958 the author and the Water Resources Engineer of the Sierra Pacific

Power Company in Reno were appointed by the Nevada Interstate C001pact Commission to ma.ke a study of lands available in the basins of both the Carson and the

000148 4

Truckee Rivers vhich had potential for future development as residential,

industrial, or farm areas, or for recreational use, a.nd the approx:L'!lB.te amount

of vater necessary for complete development of these areas was determined. Attached

hereto as Plate D is a sum:nary of these lands in the Basin. Some of

these areas are nov under various stages of development. The vater supply for

these lands vould have to come from the Carson River a.nd would result in reduced

flovs to the rrevlends Project and the Stillwater Wildlife Management A:rea. '!'his

report is on file with the California-Sevada Interstate Ccmpa.ct Commission.

The Bureau of Sport Fisheries and Wildlife should develop within its

organization men, or else hire outside help to obtain men, vho are qualified to

continually study such probleos where water supply may be threatened and should

not accept new studies or reports that might effect this wter supply without

careful study and re-evaluations of such proposal..s. A policy of indifference

and e.cquiescence to these proble!!la vill lead, inevitably, to the vi.ld waterfowl

follovin6 the path of tbe passenger pigeon to extinction and the disappearance

of any need for resting and nesting areas for extinct birds.

3· Possible Effects of Irrigation of India."l Lands Under \-/ashoe Project

The Truckee River Decree, In the District Court of the United states in and

for Nevada, in Eg_uity fucket A-3; The U. S. of America, Flaintii'f YS. The Or-:­

Water Ditch Company, et al, Defendants, sets out the extent of the Pyramid lake

Reservation Indians' right for agricultural ~~ter in the amount of 30,o86 acre feet a.."l!lually. Whether this ~s all of the wter right to vhich the Indians are

entitled is a question that is as yet u."ldetermined. The Truckee River Decree,

although it sets out the Indian agricultural right, does not provide where this

'W'B.ter is to co!:l.e fro:n. As the situation nov stands under this Decree, if the

00014~1 5

Indians vould de.rrw.nd their full amount of water; that vater would have to come

out of the Nevlands Project supply and 'liOU.ld reduce the amount avail.a.ble for

diversion on the Project to that extent.

It would be ">ell to point out at this time that the construction of the

Nevlands Project included the diversion d..am on the Truckee River at Derby. This

dam completely destroyed the big cutthroat trout in Pyramid Lake. This vas a remarkable fishery. It furnished a substantial part of the food supply of the

Pyramid Lake Indians and provided fishing in the Truckee River--including Lake

Tahoe. These fish are now e..xtinct--thanks to Derby ~. The same disregard for recreational and econcmic uses under Washoe Project, as proposed, will do the seme tb..ing to the Stillwater ·.vndlife Management Area marsh and the waterfowl vill follow the path of the Pyramid Lake trout .

4. t.Jater Historically Available to the Stillwater Area and Carson Lake Pasture

The •-ater that bas been delivered to the Carson lAke Pasture and the Still­ water ~ildlife Management Area in the past bas been drainage water, spills over

Lahontan, end winter paver water. The records do not show that Sizy deli very direct from lahontan has ever been made to these tvo areas. The actual record of quantities delivered is not too good.

I refer at this point to a water requirement analysis report made by Dale

Sutherland, Wildlife Management Biologist, Bureau of Sport Fisheries and Wildlife, dated January 18, 1957, as to the past supply of water to the Stillwater Wildlife

Management Area and the future supply required. These records 1ncllcate that at its current stage of develo:poent the Stillwater Wildlife Management Area can beneficially use 131,000 acre feet of water annually. Under ultimate develop- ment this amount could be raised to 154,000 acre feet. AI!. indicated by Plate D,

consumptive use of >mter may reach 63 1 000 acre feet annually at Carson lake Pasture.

5. Future Water Available to Still1oreter Area under \ola.sboe Project

An analysis of the tabulations and the assu::xptions used by the Bureau of

Reclamation in its studies on the '.lashoe Project indicates that under conditions

of washoe Project the supply of vater to the Still•~ter Wildlife Management Area

vould be greatly direinished and vould be of a quantity vhich vould maintain only

a very small part of the prese:nt develop:1ent as a marsh e.nd, in effect, vould

destroy the Stillwater Area a.s an important point in the Pacific Flyvey.

Under 'dashoe Project, points of vater delivery would re:nain the same, but quantities would be dbinished. As a possible measure to obtain so:ne additional drain water , tva possible drain d!versions could be accomplished to procure vater nov going to Canvasback Club lands.

A study of the Draina{;e Ha:? of the Ivevla.::His Project shovs that the ::lB.jor w-ater supply going into the l"a.""lage~ent Area bas come from one trunk drainage systeo, the Diagonal Drain. The tvo nev possible drainage diversions are:

( 1) The first in Sect ion 24; Tovnship "1ft., N. , Range 30 E. , MDB&M. This vould require the construction of a short canal and a pumping plant. This diversion vould supply the drainage water fro:n an area comparable to, or slightly larger than; the area \rhich has supplied the vater to the !l.a.na.ge::nent Area in the past.

(2) The second possible diversion would be in Section 36, Township 20 N.,

Range 30 E., !.A})B&l>'.. This vould require the construction of a canal approximately

4 miles long, with a capacity of approximately 30 crs., and vould deliver water into the ~ea in Section 7, Township 20 N., Range 31 E., l®E&H, and vould provide drain w-ater fro:n a substantial area. These diversions of drain vater, nov being used at the Canvas back Gun Club and the ::ent -Oser holdings, vould come under direct and cor:Iplete control of the stillwater \-.'ildlife !IJB.Ilagenent Area. Up to

000151 7

10,000 acre feet of water of this type is nov being consumptively used on the mentioned private lands annually.

6. Availability of Kev Water Sources

Additional sources of vater to ~e nade available in relation to the Truckee- carson Irrigation District operations are practically no~existent. u~der the present conditions; and under Washoe Project conditions, it will be necessary for the District to salvage drain.a.ge waterwha"e'a' this could be done. This vill be water that has fornerly gone :!.nto the Stillvater wilCJ.ife Hanageu ent Area.

Hashoe Project conditions vould force the District into a maj or canal lining project vhich, again, vould nean less water in the drains and less wo.ter to the

Management Area.

At the present time the Truckee-Carson Irrigation District's ~~ing Leard of Directors has di~iculty recognizing,~ or ignores, that the still~o.ter wildlife

Me.nage:nent Area is a.'1 economic unit vhich should be considered part of the eco::J.or:xy of the Ne-w lands Project in Churchill County. '7ne Board also fails to recognize that any vater supply proble::1s \oo'i th the Wildlife Area should be given the sa':le consideration as the vater supply to the irrigated lands set by the Board. ~be

Truckee-Carson Irrigation District Eoard does~'t seau to be able to recognize the econo::nic importance of an area like the Stillvater Wildlife 1 · £.nage;!l e~t /l.:rea in connection with the Nevla.'"lds Pro ~ ect. Tangi"c le a.'"ld inta..ngible values are involved which may not be so readily evaluated in ter.rus of ~ney but which are of i;mnense value to the econor:J.ic stability of northwestern !ievada and to sene :... extent to the entire population of the United states •hich is interested in various types of outdoor recreation. An att~pt will be made to coopare both the tangible and intangible values of the stillvater 'i-li ldlife Hana.ge:!!lent Area in the s~ of this report.

7· quality of Water

Due to the i:lcrea.sing use of detergents for various purposes, and the L'1B.bil- ity of present sewage treatment p~ts to destroy these detergents, the ~uality of 'lffiter going into the stillwater '..!ildlife i·la.Da.be:nent f..rea should be carefully watched. N3 the areas around ?.eno a.."l.d Sparks on the Truckee R~ ver E:.Ild Carson

City and Iiew mp::.re on the Carson River continua.l.ly gro•r, the a:J.ount of detergents getting into the stree::1 flO\o{ fro::~ the treat:-:1ent plants will increase a."ld could reach the point where it would. ser:..ously effect plant t;rowth in the Stillw.ter

~h area and also seriously effect the vaterfovl nov utilizin; the A:eu.

1 It is not yet kno>m vhether the effects of these deter.:;ents are c·.nulati ve.

This should be carefully watched by the Pureuu of S:;>ort Fisheries a.:1d 'r!ildl:..fe to deter:!l.ine vhether these detergents would effect vildlife, possibly by reC.ucing reproduction or shortenin6 life periods. A proe;ra.:n of syste::atic vo.ter sa":l?line; should be set up to determ~ne at all t~es the amount of this contamination entering the still'lffiter Wildlife l·~at;e;:Jent f..ree.

Wildlife biologists should vetch contL~uously to see if these detergents a=e effecting the refuge areas in a.'1Y ·w~ay. At the present time there see.":l.s to be sone evidence to support the fact that these detergents are already effectin£ fishing in areas in the ~J ewlanC.S Project where fo!'Taerly fishi..ne ~as been enjo:,•ed.

S~ and Conclusions

A person traveling the higb~~ys at present cannot help but be ~zed by the gro·.. '"'.....ng number of people that are en: oying the Public Daoain, Public ?arks, and. areas such as the vildlife refuges. ~~ch areas provide recreational uses for types that vary fro:n rock hounds and bird watchers to bunters and fishe!'::len. For ..... this reason alone, the Fish and ~ildlife Service should use every effort to secure definite water supplies for the Stillwater Wi ldlife JJ.ana..~enent Area. The sa.:Je

000153 9 forces are at wrk today that destroyed the buffalo and the passenger pigeon and could in time destroy most of the present or possible future wildlife areas. Un­ less the Bureau of Sport Fisheries and Wildlife takes a definite and positive stand on water supply to refuge areas 'W'here the water supply to the area is involved vith other interests, or vhere future denands may be made on the ~~ter supply for other purposes, such waters may be forever lost.

Under the Washoe Project studies, the Bureau of Reclamation has assigned credit for certain recreation benefits that vill accrue under the Washoe Project.

On the other band, the Washoe Project operations will certainly destroy, or greatly limit, the recreation areas in the stillwater Wildlife Management Area and reduce the value of Lahontan Reservoir for recreation. When these values are balanced against each other, the Bureau of Rec~tion should subtract these suns from its cost-benefit ratio figures or else make definite commitments for water enough to maintain the recreational areas at still~~ter 1-.'ildlife Ma.na.ge!!lent Area a.nd

Lahontan Reservoir already developed.

The Bureau of Sport Fisheries and 1-.'ild.life should take a definite stand on

~-ater supplies to the still~-ater Axea and should obtain firm co:r.:oitl:lents from both the California-Hevada Interstate Cor:rpact Co:::Jrrlssion and the :Bureau of Reclamation as to this water supply. I suggest that this can be argued from three vie~'J>OL'lts to establish water rights for the Managecent Area.

A. Use of water since the wildlife area \78.8 established.

B. The possibility of establishing the existence of riparian rights to the

Area should be thoroughly exa:::lined by the legal staff of the U. S. Fish and

Wildlife Service.

C. The theory genera.l.lY spoken of as paramount rights that dates back to the treaty of Guadalupe Hidalgo. This treaty affects this general area vhich

000154 10 ceded to the United States--including the Stillwater Wildlife Management Area.

Under this treaty, va.ter 1n the area vas ceded vith the la.'ld and as attached to the land.

It 'lrould be superfluous to :point out the econcmic values involved in these management areas--they are f'ul.ly covered by existing studies and reports--easily available.

Intangible values cannot be deter.nined in terms of money. In Nevada, at the present time, for a total of $15 for licenses and permits a citizen has the right to use and enjoy the outdoor benefits of any kind--including hunting and fishing--in Nevada for a. year. What value can be placed on this condition in terms of the American-vay of life and where else in the vorld, except in the United

States, does this condition exist 7 '1'he value of this should be kept in mind always by the Agencies that are involved in maintaining these conditions.

The construction of' the Washoe Project, as presently planned, vill lead inevitably to a greatly reduced, or d.estruction ot, the Still'W'B.ter 'Wildlife l.fanagement Area. In establishing a definite water right for the stillwater Wil.d­ li!'e Ha.na.ge::1ent Area, the legal department of the U. S. Fish and Wildlife Service should. give thorough study to the idea of the Wildlife Service intervening in the as yet undete:nnined Carson River Suit to the end that a definite va.ter supply could be set up for the still'IJB.ter Wildlife Ha.na.gement Area. A positive stand should be taken on all of these water riE;ht problems and not be "let go by the board" due to indif":ference or unsettled :policy.

The Truckee-Carson Irrigation District, as a party to the Three-Way Agre~~ent that created the stillvater Wildlife Ma.nagement Area, has not kept good. faith, and at times has been antagonistic tovard.s the Still'IJB.ter Wild.li!'e Ma.nagement

Area and since the creation of the Management Area has ma.de several drainage

000155 ll diversions that have reduced the supply of water available for the 14anagement Area.

This is another reason that the Bureau of Sport Fisheries ~~d h~ldlife should give serious consideration to the idea of withdrawing the e~tire stillwater Wild- life Manage.'":lent Area for wildli:fe purposes--assU!Iling it obtains a firm water supply for the still~~ter Area.

000159 PLATE C DISCUSSION

Plate C is a bydrograph indicating Lahontan Reservoir ~~ter releases for the period 1930 to 1960. The water spilled and winter paver wter columns repre::;ent vre.ter that he.a gone into the stillvater Wildlife M.anagement Area.

Under Washoe Project conditions, these quantities would largely disappear as they 'I.'Ould be taken up at We.tashea.mu Reaervoir. Washoe Project vould require that any 'l.~ter that is used for winter power generation at Lahontan be stored in suppleznental reservoirs for irri88-tion use the following season. This would :1ea.'1 that these quanti ties shown in the hydrograph would no longer be available to the Stillwater '1-lildlife Hanasenent Area.

000160 PLATE F DISCUSSION

This is a tabulation shoving the vater situation through the non-irrigating months.

Col~ 1 represents gain in acre feet of storage at Lahontan Reservoir dur- ing the non-irrigation season.

Column 2 is total vater available to Lahontan Reservoir during the non-irrigation season.

Col~ 3 is total loss of water to Lahontan during the non-irrigation season and includes Truckee Canal loss, Lahontan evaporation and seepage, and flood spills (in years marked vith an asterisk).

Column 4 figures represent historic vinter power water releases at Lahontan

Reservoir. This vater ha.s mostly gone into the stillvater Wildlife Management

Area. This is -water that will not be available to Stillvater under operations of the Washoe Project. Washoe Project would require that any vater used for winter power generation at the Lahontan Power Plant be stored in supplemental reservoirs for irrigation use. These supplemental reservoirs are: Sheckler

Reservoir: S-Line Regulating Reservoir, Ole's Pond Reservoir, and the Harmon

Reservoir. The present capacity of these supplemental reservoirs is approximately

20,000 acre feet. The winter use of water for power Jrould be li.mi ted to this amcnmt under washoe Project. As indicated by Column 4, power releases at

Iahontan have provided approxir:la.tely 50,000 acre feet annually to the still-water

Wildlife Management Area. This water would be lost to the Still-water io!ildli:fe

Management Area under Washoe Project.

Column 5 indicates the actual winter loss at Lahontan Reservoir due to seepage and evaporation. The amount varies somewhat each year and is not an average annual figure (entire year) as assumed by the Bureau of' Reclamation in its Washoe Project Studies. Years during which flood spills were released are indicated by an asterisk. 000161 PlATE G DISCUSSIOH

Fle.te G is a so.1mary of a 30-year day-to-day study of the Truckee Canal at the Derby Diversion Dam.

ColU!Ill'l 1 represents tbe ar:1ount of water historically diverted into the

Truckee Canal at Derby Dam.

Colunn 2 ind.:.cates tbe quantity of water 'l.'"hich could bave been diverted bad the full capacity of the Truckee Canal, assuned at 1,000 cfs., been utilized. v!as!loe Project :proposes to util:!.ze this quantity of "tJater at the proposed ..... 'h'atas~1 earm :Ji vis ion ou the Carson ~i ver. Act ual:y, the WJOll:jt of additional water which could be diverted would depend also upon the availability of storage space in La.Oontan Reservoir and anticipated flow on the Carson ~i ver at Fort

~urchill. i~hoe ?ro~ect studies indicate ~• average additional diversion through the 7ruckee Canal, over past •historical use figures: of 20:000 acre feet a..'1.Dually. As indicated by data in Column 2, 20, 000 acre feet of divert ible water are not always available at :;)?rby Dazl. This would indicate the :cecessity of additional storage o~ the Tr~ckee 21ver to provide car~JOVer water to be r~e av-ailable at :uerby De.m. lJ:::mg-terJU carryover storae;e is "lOt feasible ~"1der cli:J.atic and soil conditions in this area--tl:e evaporatioa a...

Di.:fference 215,100

The subst~•tial d;~ferenc~ bet>veen the tva gross supply figures, 215,100 acre feet annually, indicates thet the ~~reau of Recl~~tion has greatly overestimated the

:future ""ater su::p:ply tc the St:!.llva.ter 'Yiildli..fe J.ianagement Area. This results pa.--tly from the :nethod of using Arithmetical Means which do not accurately predict water a\railability. This is evidence t~at t~e constr~ction of the Washoe Project, as prese~t~v plruL~ed, ~~ll lead to the reduction--or destruction--of the stillvater

S. T. Earding Report on ·~later Availability to the Newland.B Project - (It en 6)

Quoting from s. T. Harding's January 15, 1960, Report prepared f'or the

71--.lckE=e- Carson Irrigation District on the effect of the Hashoe ?reject on the

Irrication District; ?age 9:

"USE OF HATER FOR COJ.1HUI'ITTY PAST"u!'..ES AND 1-.l:LD LIFE

'"No provision for a 'I.""E.ter supply f'or such uses ha.s been m.a..d.e in the preceding discussion. Here again there is not a dependable vater supply for such uses in excess of the demands for crop lands. The value of both pasture use and vild life refUges is recognized and all of the surplus stre~ flov and drain and return flovs

000167 PLATE E - Continued that may be available should be used for such uses. S'..1ch uses, however, should not be recognized to the extent vhe~e they can require delivery of vater needed for crop land either with the Truckee-Carson Irrigation District or in other crop areas on the Truckee or Carson Rivers. The District has control of its ovn use of vater on its co~ity pastures. It should be careful in any agre~nents for vater for vild life use to restrict its oblibations to delivery to ~~ters not useful or usable for District purposes."
