Assessment of Long-term Trends in the Oxygen Resources of a Recovering Urban Lake, Onondaga Lake, New York
Open accessAbstract
Long-term trends in dissolved oxygen (DO) resources are documented for ionically enriched, hypereutrophic Onondaga Lake, New York, for 1978–2002. Assessments of oxygen resources are based on DO profiles of 1 m resolution conducted hourly to weekly during April-October. Closure of an industry that operated on the lake's shore until 1986 resulted in an abrupt decrease in primary production and organic carbon deposition and marked changes in hypolimnetic and epilimnetic DO regimes. The hypolimnetic DO response was gradual, reflecting the influence of sediment feedback. The onset of complete hypolimnetic anoxia, which occurred by early June through the 1980s, took place approximately one month later over 1997–2002. The anoxic factor decreased significantly over the study interval, from 97±5 d to 67±2 d. Epilimnetic DO concentrations responded rapidly to the abrupt change in lake metabolism. Before closure of the industry, 41% of the April to mid-September DO observations deviated from saturation concentrations by >30%. In the years immediately following industry closure, this degree of disequilibrium occurred in 23% of DO observations. Percent saturation values during fall turnover increased gradually during the study, from 49±2 to 65±2. DO concentrations in the lake's upper waters have been subject to substantial diel fluctuations (>4 mg/L), with daily minima and maxima generally occurring at approximately 7:00 and 16:00, respectively. Measurements made at 11:00 and 22:00 were most likely to be representative of daily average conditions. Diel variations and sampling frequency were demonstrated to be important issues for the evaluation of status with respect to water quality standards for DO. Levels of DO in the lake's upper waters have been positively correlated with chlorophyll a concentrations (r = 0.52). Despite marked improvements in DO resources, the lake continues to lack cool, well-oxygenated waters during summer necessary to support coldwater fish species.

TL;DR
Long-term monitoring of Onondaga Lake (1978–2002) shows improvements in dissolved oxygen after the 1986 soda ash facility closure, including later onset and shorter duration of hypolimnetic anoxia and higher fall upper-water DO saturation. However, severe fall lake-wide DO depletion and lack of oxygenated cool-water fish habitat persisted through 2002.
Key findings
- Hypolimnetic anoxia duration decreased from a high of 157 days in 1981 to a low of 98 days in 1997; during 1997–2002 it averaged 101±1 days. The anoxic factor decreased significantly (p=0.001) from 97±5 days pre-closure to 67±2 days in the new quasi steady-state, and the onset of complete hypolimnetic anoxia occurred about one month later.
- Upper-water DO became less variable, and fall percent saturation was significantly higher in 1997–2002 (65±2) than in 1978–1986 (49±2) or 1987–1996 (50±1; p<0.001). Still, DO <5 mg/L occurred throughout the water column during fall mixing in all but three study years (1999, 2000, 2001), and in 5 of 23 years DO fell below 2 mg/L.
- In 1999, hourly upper-water DO ranged from 0.2 to 8.2 mg/L within a day; the median diel range was 1.7 mg/L, with <2 mg/L on 60% of monitored days and >4 mg/L on 9%. In 2002, monthly or bi-weekly sampling found 1 violation of the 5 mg/L daily-average standard, whereas daily sampling found 11; daily sampling found 2 violations of the 4 mg/L instantaneous standard versus none with weekly sampling.
- Fish habitat did not substantially improve: the lake’s DO resources were no better in 2002 than in 1988 for cool-water habitat, and during July–September 2002 depths with temperatures ≤20°C were essentially devoid of DO. In October 2002, DO fell below 5 mg/L throughout the water column.
Methods
- Onondaga Lake was monitored at its deepest location (~19.5 m) during April–October/November 1978–1982 and 1985–2002. Profiling was 2–3 times per week in some years, weekly from 1990–2000, and at least daily in 2001–2002; DO and temperature were measured at 1 m intervals with calibrated probes, plus hourly DO/temperature at 1 m during April–October 1999.
- The anoxic factor (AF) was calculated from DO profiles, anoxic sediment area, and lake surface area according to Nürnberg (1995). Analyses used three periods: pre-closure (1978–1986), transition (1987–1996), and new quasi steady-state (1997–2002), and considered onset/duration of anoxia, AF, areal hypolimnetic oxygen deficit (AHOD), saturation deviations, seasonal and diel dynamics, standards status, and sampling frequency.
- Statistical comparisons included Welch t-tests, correlations, and best-fit polynomial curves with coefficients of determination; sampling-frequency effects were evaluated using robotic buoy measurements from 2001 and 2002.
Limitations
- The paper states that near-bottom anoxia metrics could not be calculated in years when complete spring turnover failed (1980, 1985, 1986, 1993, 1994), that the July 19 diel observation was excluded because probes could not measure DO above 200% saturation, and that hypolimnetic pools of oxygen-demanding reduced species were presently unquantified.
- The paper states that diel DO patterns are rarely ideal and that sampling frequency/timing strongly affects assessment of DO standards; a measurement at 11:00, the hour most appropriate for estimating daily average, ranged from 80 to 130% of the true daily average.
- Evident from the text: the monitoring record has a gap in 1983–1984, sampling frequency and instrumentation changed over the study, the diel analysis is limited to 1999, and the fish-habitat comparison uses only 1988 and 2002.

The Abstract (p. 2) says the facility discharged about 1.3 million metric tons of ionic waste annually at peak production and identifies high salinity as an impact. The Ionic Waste section (p. 6) estimates an annual average of 1.2 million metric tons for 1974–1985, but does not establish that discharges exceeded 1.0 million metric tons every year throughout 1940–1986. The stated duration therefore overextends the evidence. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-16.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-16.
Cited sources are checked by gpt-6-sol.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
