INTRODUCTION
The Water Resources Department of the St. Johns River Water
Management District has prepared this annual report for the water
year 1984 (October 1983 through September 1984). This report is
directed toward state, regional and local governmental units,
planning agencies, agricultural and business concerns, and inter-
ested members of the public; and is intended to provide
information on hydrologic conditions in the District.
The report is divided into two sections. The first section
deals with the status of the resource: 1. Rainfall, 2. Floridan
aquifer, 3. Surface Water, and 4. Water Use data. The second
section, the Appendices, contains rainfall statistics for 1951 to
1980 (the period used for calculating normal rainfall) and for
the available period of record, and a list of current technical
reports and papers available through the Department.
STATUS OF THE RESOURCE
Precipitation in the St. Johns River Water Management
District occurs primarily as rainfall. The isohyetal map of the
normal rainfall which is the annual mean for the period 1951-1980
is shown in Figure 1.
The annual rainfall variation in the District for the water
year 1984 is shown in Figure 2. Rainfall within the District
during the 1984 water year ranged from a low of 38.57 inches at
structure S-157 on Canal C-54, seventeen miles south of Melbourne
in South Brevard County, to a high of 78.90 inches at Orange City
in Southwest Volusia County. Average rainfall for the 1984 water
year calculated using the isohyetal map (Figure 2) was about 60.0
inches as compared to a District mean of 52.0 inches (based on
Figure 1) for the period of 1951-1980. The rainfall was above
normal for three consecutive years since the 1981 drought, the
mean rainfall for 1982 and 1983 being 62 and 55 inches,
respectively.
The departure from the normal rainfall for the 1984 water
year is illustrated on Figure 3. Rainfall was above normal
throughout most of the District. Portions of Alachua, Marion,
Lake, Brevard, Osceola, and Indian River counties received below
normal. Several areas received rainfall of 15 to 20 inches above
normal. In summary, rainfall for most of the District during the
1984 water year was greater than the average of 1951 - 1980,
which is the current normal.

Figures 4 and 5 display the potentiometric surface of the
Floridan aquifer during May and September 1984, respectively.
The change in potentiometric water levels between the normal
seasonal low in May and the seasonal high in September is shown
in Figure 6. While most areas of the District experienced a rise
in potentiometric levels between May and September, the levels in
the western portions of the District, Alachua, Baker, Bradford,
Clay, Marion, Putnam, Western Duval, and Nassau counties dropped.
The area of greatest rise in the Floridan potentiometric levels
occurred in Indian River, central Orange, and western St. Johns
counties. Table 1 summarizes the monthly and annual changes in
the Floridan potentiometric levels for selected observation wells
throughout the District.
Figure 7 shows the locations of four long-term monitor wells
in the District. The Alamana well, V-0101 in Volusia County,
showed little overall change in potentiometric levels during the
1984 water year (Figure 8). Potentiometric levels in Well D-
0160, at Neptune Beach in Duval County, dropped approximately 4
feet from February 1984 through September 1984. However, overall
levels from September 1983 to September 1984 remained nearly con-
stant with only a 0.40 foot rise. In the Brooklyn well, C-0120
at Keystone Heights in Clay County, the potentiometric level
dropped nearly 0.8 foot from September 1983 to September 1984.
The Platt well, BR-0645 near Melbourne in Brevard County, also
had decreasing potentiometric levels during Water Year 1984.

At the end of the water year, potentiometric levels in the Platt
well were approximately 1.6 feet lower in September of 1984 than
in September of 1983.
The Keystone Heights and Alamana wells are located in
recharge areas which are sparsely populated. Variations of water
levels in these two wells are the result of differences in
natural recharge and discharge. The overall decrease in poten-
tiometric levels at the Keystone Heights well indicates greater
discharge during the water year than recharge in the hydrauli-
cally connected areas down gradient in the Floridan aquifer. The
overall increase in potentiometric levels at the Alamana well
indicates greater recharge than discharge.
The Neptune Beach and Platt wells are located in areas of
high demands on the Floridan aquifer. The fluctuations in water
levels are directly affected by heavy ground water pumpage. The
Neptune Beach well reflects heavy urban withdrawals. The Platt
well reflects predominately agricultural demands.
The period of record trends of all 4 wells indicate slowly
dropping potentiometric water levels. The potentiometric levels
in the Platt well appears to have stabilized after 1981 or 1982.

The streams and rivers of the St. Johns River Water
Management District derive their flows from runoff of precipita-
tion and from ground water discharge. Locations of stream or
lake gaging stations used in the preparation of this report are
shown in Figure 9.
Figures 10 through 19 present monthly streamflow data for
water years 1982-1984 for selected gaging stations in the
District. Figures 20 through 29 show monthly elevations for some
principal lakes in the District. The median shown on these
figures indicates the flow (or stage) value equaled or exceeded
for 50 percent of time during the period of record. Overall
rainfall was about 15 percent above normal for the District
during the 1984 water year. In general, streamflow and lake
elevations are above median for most of the months. However,
because of relatively low rainfall conditions in the upper St.
Johns River Basin in 1984, the mean annual discharges at dif-
ferent locations in this basin are below those of 1982/1983
(Figs. 11-13, 15, and 16). A drawdown program was conducted on
Lake Griffin which is reflected by its 1984 elevations in Figure
28.
Table 2 presents the annual mean flow data for different
tributaries in the lower St. Johns River Basin.

Water use data are collected annually for the 19 counties
within the St. Johns Water Management District. Water use is
compiled for the following categories: Public Supply; Domestic
Self-Supplied; Industrial Self-Supplied (including
Institutional/Recreational Self-Supplied); Agricultural
Irrigation (including Livestock Use); Thermoelectric Power
Generation; Heat Pump/Air Conditioning; and Free-Flowing Wells.
The total fresh water use in the District for 1984 amounted to
1,507.05 MGD (Table 3) of which ground water totaled Ir217.04 MGD
(80 percent) and surface water 290.01 MGD (20 percent). There was
6.26 MGD of water reuse in the District for 1984 which was not con-
sidered in these figures. Of the 1,217.04 MGD ground water, 0.84
MGD was saline used in Reverse Osmosis for Public Supply.

The total population of the St. Johns River Water Management
District in 1984 was 2.575 million of which 79% was served by
public or private water suppliers. The monthly water use for
Public Supply in 1984 fluctuated from a peak in May of 377 MGD to
a low in January of 282 MGD (Figure 30). This increase in
pumpage is due primarily to lawn irrigation in the late spring
and early summer seasons.
For further details in water use refer to the "Annual Water
Use Survey: 1984", Technical Publication SJ 84-7 (see Appendix B).
Agricultural Irrigation was the largest fresh water use
category for 1984, accounting for 41% of the ground water used
within the District (Figure 31). The second largest category was
Public Supply using 26% of the fresh ground water. Other
categories with substantial amounts of ground water use were Heat
Pump/Air Conditioning (12%), Industrial Self-Supplied (11%), and
Domestic Self-Supplied (7%). Free-Flowing Wells accounted for
2%, and Thermoelectric Power Generation accounted for less than
1% (0.4%) of the total ground water used in 1984.
The major fresh surface water use category in 1984 was
Agricultural Irrigation, accounting for 90% of the total surface
water use. Public Supply, Industrial Self-Supplied, and
Thermoelectric Power Generation accounted for the remaining 10%
of total fresh surface water use (Figure 31) .

Brevard and Indian River counties were the largest users of
fresh water for 1984 (Table 4), accounting for 289.63 MGD (19%)
and 279.51 MGD (18.5%), respectively. Orange (183.08 MGD), Duval
(148.37 MGD), and Lake (143.88 MGD) counties were the next three
largest fresh water users. These five counties accounted for 69%
of the total fresh water use.
Brevard County, the largest fresh ground water use county in
1984, accounted for 259.97 MGD (21%). Other counties which
withdrew over 100 MGD of fresh ground water were Orange (152.86
MGD), Duval (144.71 MGD), Lake (125.87 MGD), and Indian River
(105.11 MGD). Indian River and Brevard counties' totals include
0.82 MGD and 0.01 MGD, respectively, of saline ground water used
for reverse osmosis.
Indian River County was the largest fresh surface water use
county in 1984, accounting for 174.40 MGD (60%). Other counties
using substantial amounts of surface water were Orange (30.22
MGD), Brevard (29.66 MGD), and Lake (18.01 MGD). Lake (2.52 MGD)
and Duval (1.56 MGD) counties used the largest amount of reuse
water (65%).
Figure 32 shows each county's fresh water use by source
(refer to Table 4 for actual values). Water use shown for those
counties partially within the SJRWMD (Alachua, Baker, Bradford,
Lake, Marion, Okeechobee, Orange, Osceola, and Polk) represents
the data from the St. Johns River Water Management portion only.
The remaining portions of those counties are not accounted for in
this report.

APPENDIX A
ANNUAL RAINFALL STATISTICS
The mean rainfall for 1951-1980 (the past three decades en-
ding in 1980) is considered as normal for a given gaging station.
However, other rainfall statistics, such as the median (value
equaled or exceeded for 50% of time), middle or normal range (the
range covered by the middle 50% of the annual rainfall values),
maximum and minimum during the record period, the lowest mean
annual rainfall (drought rainfall) for a specified period, etc.,
will be of interest for comparison with 1984 water year rainfall
data.
For several long term NOAA (National Oceanic and Atmospheric
Administration) stations located within and close to the
District, the foregoing rainfall statistics including drought
rainfall for 3-, 5-, and 10-year continuous periods are presented
in Table A-l for 1951-1980. In addition, Table A-2 considers all
rainfall data available through calendar year 1984 and presents
similar statistics.
