Gentlemen:
At e Joint meeting of the lake Apopkn Reorestion, Utter Conservation and
Control Authority with the atth Recreation, Rater Conservation sod
Control Authority the Department of Voter Resources was requested to convene
a special omittee made up of technical representstives or the three authorities
and of the Department of Voter Resources to revisv the pious under which ell
three of the authorities were opersting, vith n view 01 deternining it chums
could be made that would be generally hemiicisl without undue increase in hnsards.
Follovixu written confirnstion by both the We end Orange County Authorities
e canittee was roused consisting of Mr. lheodore Jonson, of Gee I: Jenson Con-
sulting Engineers, representing me County; Mr. J. 8. hireir, oi' Maurine a.
Connen I. Associates, Inc., Consulting Engineers, representing Orange County;
Mr. Edwin V. Eden, 3n, representing the U. 8. Any Corps of Engineers and
Mr. Curl Daugherty, Senior Field Engineer, representing the Depertnent 01'
water Resources. The writer served on Chairmen oi' the nominee and egreed
to undertake the preparation of the cousittee report contained herein.
The omittee held so orgenisetion meeting at the Orange Court Hotel
in Orlando on September 15, and e public hearing at the American Legion Home
in winter Carson that night. On Septelher 16, public henrings were held of.
'lhvsres, Clement, and heesbum.
The oonittee resembled st the U. 8. Army Corps of Engineer's ofce
in Jacksonville on September 26, st which tine the nesenhled date was reviewed
nnd recon-sensations are adopted. The rolloving conclusions end remndations
were approved by the eonittee:
1. take Apopka.
lake Apopka is a very broad and shallow lake ehich is of great import-
ance to local and visiting sportsi'ishina enthusiasts and is or great econaic
iaportance to installations around the lake who provide services for fishing
parties. Statennts at the public hearing indicated that a decrease in
aux-thee elevation of even a few inches night he very detriaental to the
balanced fish population of the lake. and that accordingly. it is desirable
to carry operating levels as high as possible without unreasonable hazards
or floods.
The canittee is or the opinim that the lover level or the conservation
pool (the normal vorkins level) would be raised In its present elevation
at 66.0 rs. above neon sea mm to 66.5 ft. above mean sea level. It
appears that this shoud be done with a corresponding effort to retain
a stage of 67.5 ft. at the beginning 0! the dry season, shout loveaher let.
This raising of operating levels will lessen. but not eliainate the recurrent
problea of excessive low water. It will. however, inane-e m. the
possibility of reaching stages scaevhat ow:- 68.0 ft. and approaching 68.5 ft.
follovitu tomntisl tropical rainstorm vhich occasionally occur.
The cc-ittee recessive, however, and tail attention to this basic net
of will-clog: Vheneve. starsae is red.:ei 'hy raisin; stages) there lust
be an increase in disrmarge capazt'. :r a degree of security during periods
or excessive rainfall: is ca: titted.
These higher stages nay tnuease the hazard to lov-lyim egrio
cultural lands protected by lav dikes and it vould be desirable to prevent
this callith iru teeming.
An important factor governing high vet season stages in Lake mm is
the asount or water vhic). can be divharged through Apopka-Beauclair Canal.
The Oklavaha Recreation, Hater Jcnservstion and tootrol Authority of Lake
Comty has requested its Orange County :mterpan to operate the lab Apopka
spillvay so as to diezharge not acre than abr-ut 250 rubic eet per second
through Apopha-heauclair :anal. This steals ft"- the unfortunate fact that
the bore Canal has a lesser ;apa':ty than the Apopks opium and is a
realistic. necessary policy if fl .1113 arr-mi lakes Beauclair. Carlton, and
Dora are to be minimized.
The anittee screed toot sun t e Limitation of discharge in the canal
is desirable, but that if the <11th is t; he liaited and if the lake Apopka
conservation pool is to be raised simultaneously, the danger of floods
during tropical storms viii be greatly increased. A possible alternative
that would greatly lessen the flood hazard would be to provide an auxiliary
outlet {rc- Lah Apopka thetagh an existing natural run into little Lake
hrris. me would pensit the raising o! the :oneervation pool to operate
between 67.5 ft. wper level and 66.5 ft. laser level with little. it any,
increase in flood hazards and Vith the possibility of restricting discharge
to the Apapka-Beauclair Canal tn an extreme naxisnsn between 250 and 350 cubic
feet per second. It appears highly advantageous to both the lake Apopha
Authority and the Mavens Auttcrity to prc-vtie euch an auxiliary outlet;
for in addition to pemitting the tester levels in Late We to be carried

the engineering dlffitultle! of merging the entire reuse of operatlcae to

flow is penning through these nine
3. Lake Iouisa, Lake Minnehaha, lake Xinneolo and Cherry Inks.
The levels or these lakes are controlled first by the operation of
the control structure on the outlet in Cherry take and secondly, by the
quantity of voter tloving through these lakes. Since there is considerable
restriction to flow through the connecting streams each lake in turn. true
Lake louiso to Cherry lake must be at a smevhst lover elevation than the
previous lake. Until restrictions to flow can be reduced and possibly
supplementary control structures can be installed, there is little that the
Authority can do but regulau the level of Cherry lake in such a vs: as to
aininite danages caused by both excessively high and excessively lov
voter stages.
The cosmittee recomendn that the Authority proceed with develop-
mental progrsn to pemit better control of the voter levels in these lobes
so soon as possible, and. in the meantime that the present working levels
of 96.0 ft. to 97.5 to. in Cherry use he maintained.
hue Minnehnhn
h. Palatlakoha River betveen Cherry lake and Villa City.
There is an existing culvert-type control structure on the Palatla-
kaha River at Villa City which tends to control voter levels in the river
wstream tour-d Cherry lake and in the tributary stren- draining the Grove-
land area.
Statements were node at the public hearing indicating that some damage
was occurring at high voter stages in the Grovelond area. loinver, there
is acne question as to whether the present structure and the present devo-
streaa voter level will per-it material change in the existir' plan of
operation, and until these have been thoroughly studied and the advantages
and disadvantages of lover voter levels carefully weighed, it is room-sanded
that the present plan be contimred.
S. lake Griffin.
we Griffin receives voter through Kaines Creek tron all of the
previously mentioned lakes and vatervws. Discharge from Lake Griffin is
into the atlovsha River which {love about six miles to a control daa and lock
at loss Bluff. The U. 8. Army Corps of Engineers has operated the loss Bluff
structure for many years and their plan or operation has been based on aoino
tuning the level in Lake criznn betveen 58.0 ft. ainin and 59.0 rt. maxi-
mum for noraal operating conditions. Predolsinant sentiment at the hearing
in leesburg favored raising this range about one-half foot, vith a minim:
of 58.5 ft. and omaximun nornal range of 59.5 ft..
Considerable discussion centered about sudden variations in lake levels
and the effect or these variations upon the tearing loose or lily pads and
floating islands; an investigation of this matter, however, revealed that
the problem of floating islands is not oev and probably the presently severe
conditions result frm the lack of continuous maintenance rather than changes
in voter levels.
-5-
The committee hes agreed thet it would be desireble to neintein the
levels in [she Griffin as closely es possible end further. thet it would be
desireble to reise the working levels to e higher elevetion if this could
be done without encountering excessively heterdous flood conditions. In
view, hovever, of the linited cmcity of the 01:1st River between Lets
Griffin end Moss Bluff end in view of the ever increesing flood discherge
requirements of the volley es urben developsente continue, it is the opinion
of the canittee thet the chenoes of deesging floods would be too greet to
chenge the present working levels et thin ties. It is sounded, however,
that every effort be node to secure s project to inprove the eerryiog
cepecity of the atlevehe chennel between late Griffin end lloss hluff and
downstream frcsn Moss Bluff if neceseery, so so to incneee the discherge
cepecity of the atlewluis River to spproxiestely 1800 cubic feet per second.
I! this is done end with good ooondineted operetion throw the beein,
it should be possible to reiee the worhiog levels of lehe Griffin to the
desireble 58.5 ft. uininun to 59.5 ft. mien. Agein, however, ettention
is celled to the exception to these steteee-nts which will exist following
short, intense reinfells. Only flood weters storage one be counted on for
use during these periods end eny reising of operetion levels will mastic-.113
reduce need storage cepecity.
6. Generel Conclusions end Becauendetions.
The comittee is in egmnt on the following conclusions:
(e) 'i'het under oornel weather conditions veters on be controlled in
the cheins of lshes within reesoneble Opereting renaes, providing ell operetions
ere coordinated end all eveileble sauces of dete on rsinfell end runoff ere
utilised.
here will, however, be periods under no: plea of operetion in
which both low leke levels end excessively high leke levels will occasionelly
occur. Conditions prevailing during the sunser of 1958 lllustrete this point.
Beeed on eveileble reinfell records end predictions of reinfell during the
sneer eonthe the euthorities lowered the veter levels in the upper lehes to
provide storage cspecity during the wet months noreelly to be expected durum
the sue-er. hian during the n-er ennths, however, hes been only one-
third of nomel so that the lekes heve never filled to the elevetion which
would be desirable entering the dry seeson. Unless unecesoneble reins occur
during the winter months it is quite possible that undesirable low levels vill
be prevelent throughout the besin during the Vinter of 1958 end 1959. These
conditions cen he eininited by coordinated aperetion, but one never be coepletely
elimineted.
(b) m geology 3f the atlewehe Resin is such thet euriece end under-
ground voters ere so c oeely interdlpeodent thet it is necessary to tote
conditions prevsiling in both into coosideretiOn in order to intelligently
predict the effects of any given set of other conditions. If. for eque,
ground voter is low, s flesh flood eey be considerably less dsesging then it
would be under high ground voter conditions, due to the loss of weter into
the ground. Cs: the other head, e flood ceused by e long period of wet weether
m extend for en epprecieble period after the rsinfsll ceeeee. due to the
discherge of ground weter into the eurfsce waters.
-6.
It la therefore, strongly recanended, that data from all sources
including, not only the four agencies repreaented on the conittee, but
also the U. 3. weather mum, the 0. 3. Soil Conservation Service, and
when required, voluntary observers be integrated to present as caplete
a picture as possible of prevailing conditions {re- the head voters in Green
Sump to and below Nona Bluff. In order to accmplish this, the Depertnent
of water hsourcea has volunteered to act as a clearing house for all avail-
able data, with consolidated copies being eent, preferably at weekly intervala,
to all agencies concerned.
(c) Preaent efforts at coordination have been Index-ater successful,
but operation by a single agency is still considered the nest deairable type.
It is means-ended that all concerned seek a method which will be mutually
satisfactory, by which the operation or the entire basin can be consolidated
into one departaent.
