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 , .19 ~II .....

Tho impact ot agricultural activitial on the watar quality ot tha Coralville Reeorvoir and Iowa Rivlr is markedly influencad by climatic and hydrological conditions, These IttOCts wara olpecially evident during the 1988 study pari~d, A review ot information relative to nitrate . concentration provides an ex~ollent example ot the signiticance ot hydrological tactors. Although a trend to increasing nitrate levels has be on ob.erved .inc. 1973 it is avident trom Table 21 that lIlaximum l.vels occur during high' tlow periods. This was especially evidant during the current study whan loan nitrate concentrations in tho upstream river tall to 1.4 m~/L (al NI, the lowaet moan value obsorvod Dinco 1977.

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 ~II ."~._,_.._..........".,,. , , , I 1 I I I 1 . j, ; , i -----.-.,-',-"...,--,-,..,..

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).

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 except when the waters are materially attected by surtace runott."

The lack of 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. .

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 CAllO of chlordano lovels which averaged 70 and 78 U g/kg in tho 1985 and 1987 fish samplos respectively, These lcw 24 , f I I I i , , I I I, I i I I I I I I i I .
