2 order to define and recommend appropriato protective measures,
3 the director shall undertake a study to identify options or
4 limitations on activities in the area adjacent to streams
5 which ar~round to impact on water quality. In conducting the
6 evaluation and preparing recommendations, the department shali
7 consult with the department of agriculture and land
8 stewardship, the Iowa state university of science and
9 technology, and the director of the Leopold center for
10 sustainable agriculture. The evaluation shall include an on-
11 site assessment of measures implemented on one or more small
12 streams where the impact of restrictions on tillage or acceso
13 or other changes in management practices are likely to be
14 demonstrable. A report of the findings and recommondationo
15 sholl be provided by the director, in consultation with the
16 natural resource commissionr to the general assembly by no
("', 17 later than January l5r 1991. The report shall include a
18 discussion of management options identified or evaiuatod,
19 institutional options which could be employed, and incentives
20 or disincentives which would effect participation. Where
21 possible, the report shall identify ways to incorporate or
22 utilize ellisting state or federal programs to further the
23 effort.
24 Sec. 2. Section 4558.173, Code 1989, is amended by adding
25 the follo~ing new subsection.
26 NEW SUBSECTION. 11. Develop recommendations for
27 management practices designed to reduce or eliminate the
28 impact of indirect discharges of wastewater, runoff from
29 material handling or loading areas, or other significant
30 sources of contamination which discharge to or flow into a
31 storm sewer or drain tile. Requirements for the control of
32 erosion from construction sites shall also be developed. A

DISCUSSIOlf
The extended drought and extremely low ru~oft which -
. '. . -.. '
charactorized 1988 exerted a marked eftect on the 'water
quality of the Iowa River and Coralville Reservoir. Durinq
I
the current year mean intlow into the impoundment was only
ca. 473 cfs, tar below the estimated 1973-1988 mean ot ca.
'. ,
2210 cfs and the lowest mean flow since 1977.
Since the Coralville Reservoir Water Quality Study was
implemented in 1944, tho impacts ot agricultural activities
and the hydrological characteristics.ot the Iowa River' along
with the morphometry ot the impoundment and the reservoir
, operational procedures have been the major tactors
influencing the limnology and water quality ot the
river/reservoir system.
Early in the study }t hftcame apparent that runoft from
agricultural land rather th~n point source municipal or
industrial' discharge was the major source of silt, organic
matter, inorganic nutrionts ftnd pesticides and were the
cause of pericdic epicowlc oC'dogradod water quality that
were otten accompanied ~y tidh kills in the river and
, '
reservoir as well as tas~u 3nd odor problems in the
University and I~wa city municipal water supplies, These
problems woro most apparer.t in the earlier years of the
study when snow melt and r.ubsequent runoft introduced large
amounts of livestock wastos, that had boen applied to tho

Nitrates are not tho only paralet.r. which are larkedly
intluenced by hydrological condition. and tho ottect. ot
theae tactors become especially apparent whon the result. ot
the 1986, 1987 and 1988 studios are compared (Table 22).
,.
During the 11 month period, January-November 1988, average
flow in the Iowa River above the r..ervoir wa. ca. 670 ct.,
as compared to ca. 1,570 ct. during the lamo period in 1987
and ca. 3,680 cts in 1986. In addition to nitratos, average
levels ot suspended SOlids, tecal coliform and tecal
streptococcus organisms were lowest during 1988, whon lean
tlows were less than in 1986 and 1987. Kean valua. ot the
above mentioned parameters were sub.tantially highor in 1986
accompanying high river intlow.
Lower river stage and accompanyinq declines in
suspended solids during 1988 also resulted in relatively
high phytoplankton prOduction, as indicated by chlorophyll A
.
levels determined during the KaY-S.ptemb.r period.
Chlorophyll A levels in the Iowa River upstream and .'
,
downstream ot the impoundmant and at the reservoir surtace
averagad 177, 59 and 90 mg/H3, respectively, in 1988. These
are slightly higher than those present in 1987 when average
upstream, downstream and reservoir surtace values ot 176, 32
and 47 mg/H3 were present, and are substantially higher than

those present in 1986 when average upstream, downstream, and

observed. The high chlorophyll levels observed in the
reservoir during 1988 also appear to be related to tho

stable ,pool present during most ot the period: In past
years large algal populations wero most frequently prosent
when the reservoir elevation remained constant during tho
lummer and tall.
Large algal populations Were also trequently
responlible tor the high BOD values observed during the
summer ot 1988. The average upstream BODS valuo ot 13 mg/L
observed during the Hay-November period was the highost
,
observed since tho ItUdy was initiated in 1966. In the
. early years ot tho study high BOD values were normally
associated with the spring runott period when large amounts
ot organic matter entered the river trom the introduction or
animal wastes applied to land in the drainage basin. Oxygen
depletion and tish kills trequently occurred at this time
especially when the organically enriched runott entered the
reservoir when it was ice coyered. Oxygen depletion
problems have not occurre~ in conjunction with increased BOD
levels resulting trom algal blooms however.
As in previous years, retention ot water in the
Coralville Reservoir resulted in substantial reduction in
the levels ot several p~rameters in the river downstream or
the impoundment, as compared to values observed in the
upstream river (Table 23). These reductions were apparent

apparent when the extremely high values observed at the
upstream 'sampling location on one occasion were deleted.
No aigniticant violations: ot the Xowa':wat~~;:Quality
Standard8 were observed during the February-November 1988
period. None ot the river samples exhibited dissolved
oxygen concentrations ot less than 4 mg/L. A single
upstream river value ot 4.7 mg/L was the only river samples
containing less than 5.0 mg/L ot dissolved oxygen. The Iowa
Clan "B" water quality standards state that dissolved
oxygen values shall not be less than 5 mg/L tor at least 16
hours per day, and not less than 4 mg/L at any time.
Nitrate concentrations never exceeded the 10 mg/L (as
NI Iowa ,Class "c" water quality standard in any river or
reservoir samples. Three reservoir samples exhibited pH
values in excess ot the 9.0 standard but these high values,
ranging trom 9.1 to 9.3, were observed in the reservoir
during the summer and were the result ot extensive algal
activity rather than upstream inputs.

A number ot tecal r.olitorm samples taken trom the
recreational areas at the Coralville Reservoir exceeded the
Class "A" water quality standard tor'tecal colitorm, which
states that "trol1l April 1 through October 1 the tecal
colitorm content shall not exceed 200 organismS/lOa ml

lignificant watar quality violations in the river during a
poriod of extremely low flov is further evidence of tho
minimal impact of point source pollution on the water
quality of the Iowa River. .
In recent yoars, levels of chlorinated hydrocarbon
,pesticides in fish collected from tho Coralville Resercvir

This is not surprising sinco Use of these lubstances was
phased out during the 1970s. During 1988 no fish samples

ot 50 Pg/kg (parts per billion) well below the U.S. Food and

were also below tho 50 P g/kg de taction limit. Although tho
detection limits wore higher during the 1988 studios than
those applied to tho 1985 and 1987 posticido studies it
appears that c~lorinatod hydrocarbon pesticides are
continuing to docline, This is especially evident in the
