Three Rivers System – Summary of 2009 Data Overview Map and Sample Summary Table

• Three full water quality surveys were conducted on July 9th, August 12st and September 24th, 2009. Three additional surveys were conducted only at Buoy 316 on July 30th, August 27th and September 16th. In addition, YSI data sondes were deployed between June and October 2009 to measure in-situ water quality parameters (e.g., dissolved oxygen, pH, salinity, and temperature) at 15-minute intervals.

Seneca River Hydrograph and Flow Summary Table

• Flow conditions in the Seneca River in 2009 exhibited a pattern of relatively higher and more variable flows in spring and relatively lower flows in summer. Compared to the past two years the summer flow conditions were more variable, with flows ranging between 2,000 and 6,000 cfs and relatively short low flow periods at the beginning of August and throughout the month of September. The average summer flow rate in 2009 was approximately 1,600 cfs, which is comparable with the long-term summer average of 1,700 cfs, but higher than what might be considered a summer low flow condition (7Q10 flow is estimated at 350 cfs). In 2009 there were just two days below the 7Q10 flow rate.

Spatial Plots of Water Quality Parameters • The Seneca River water column appeared to be vertically well-mixed during the July

9th (3,350 cfs) and the August 12th (5,090 cfs) surveys, but exhibited stratification in water quality parameters during the September 24th (783 cfs) survey, especially between the Onondaga Lake outlet and the Three River Junction.

• Generally in 2009 the spatial trends of the water quality parameters were consistent with those measured under similar flow conditions in previous years (e.g., 2008 and 2006). However, the patterns in 2009 were generally less pronounced than those observed in lower flow years (e.g., 2007). A summary of the spatial trends in 2009 water quality is as follows:

o Between Cross Lake and the Onondaga Lake outlet:

Library Reference 9.1

2009 AMP Report June 15, 2010

Page 2

- Soluble reactive phosphorus (SRP) concentrations increased gradually while Chlorophyll-a concentrations exhibited a notable decrease due to zebra mussel activities.

- Chlorophyll-a data at Buoy-409 in the September river survey exhibited relatively high Chlorophyll-a concentrations (up to about 55 μg/L) in the vicinity of the Cross Lake, which decreased to below 30 μg/L at the Onondaga Lake outlet.

- Dissolved oxygen (DO) concentrations during the July and August surveys were similar in the top and the bottom layers; DO decreased steadily across the area by a total of 2 - 3 mg/L as a result of zebra mussel respiration and sediment oxygen demand. During the September survey, the DO data indicated stratified conditions in the river with concentrations being higher within the surface waters than the bottom waters throughout the reach between Cross Lake (surface higher by 2 mg/L) and the Onondaga Lake Outlet (surface higher by 3 mg/L).

- Ammonia-N (NH3-N), nitrate (NO3-N) and nitrite (NO2-N) concentrations exhibited little change, with only a slight increase of NH3-N, likely due to zebra mussel activities.

o Between the Onondaga Lake outlet and the Three Rivers Junction: - SRP concentrations remained relatively constant in the surface waters

as a result of the balancing of algal production with filtration of the remaining algae by zebra mussels, as well as mixing with deeper waters and Onondaga Lake inflows. During the September survey, a slight increase in SRP was observed, suggesting a greater influence by zebra mussel activities during that time. The top and bottom SRP concentrations were similar during the July and August surveys but the bottom SRP concentrations were higher than the top SRP during the September survey. A similar situation occurred during the low flow survey in September of 2007 – in both instances the SRP depletion in the top water was also accompanied by an increase in DO and Chlorophyll-a concentrations, suggesting that this trend is a result of phytoplankton activity.

- Consistent with past years, stratification downstream of the lake outlet was observed for salinity, DO, and to a much lesser extent for temperature, but most noticeably during the September survey. These observations can be explained by the influx of Onondaga Lake water, oxygen demand associated with sediments and zebra mussel activity, limited vertical mixing, and potential inflow of groundwater in the area of the “Deep Hole”.

- NH3-N concentrations exhibited little change during the July and August surveys and a slight stratification during the September survey, with higher concentrations in the bottom waters, which was likely due to the lower river flow conditions and possibly flux from sediments and/or zebra mussel activity.

- NO2-N concentrations exhibited little change in this reach of the river, with the exception of a slight increase in the bottom waters during the September survey (similar to NH3-N, but less pronounced).

- Increased concentrations in NO3-N resulting from lake water inflow were observed in all three surveys, although during the September survey, NO3-N exhibited the most prominent increase, including a strong vertical stratification with high bottom layer concentrations (up to 1.7 mgN/L) just downstream of the outlet. The stratification was due to the relatively high bottom concentration waters that entered the river from the lake and the limited vertical mixing in the area of the “Deep Hole”. In all surveys the NO3-N concentrations increased toward the Three Rivers Junction as a result of increased vertical mixing.

YSI Sonde Figure

Temporal trends in the high frequency DO data recorded by the YSI sondes exhibited some stratification at Buoy 409, with several periods of low concentrations (in the upper waters and more so in the bottom waters), with relatively large diurnal variations as compared to the other sampling locations. Compared to 2008, the daily DO concentrations at Buoy 409 were similar in the top waters and slightly higher in the bottom waters, with a greater swing in the daily minimum and maximum DO values. Similar to 2008, DO data at Buoys 316 and 236 showed less stratification and


Page 4

less day-to-day variability. Note that the DO concentrations at Buoy 236 were higher at the bottom water than at the top water during the first half of July. The reason for this oxygenated bottom water is uncertain; however, the large DO increase (from 1.4 to 15.3 mg/L) in the bottom water on July 3rd 2009 may suggest an equipment failure.

Seneca River Compliance and Sonde Compliance Tables

• From the routine water quality surveys, the data showed two violations of the NYSDEC instantaneous minimum DO standard (4 mg/L) for both the top and bottom waters at Buoy 316 during the August 27th survey. There were no observed violations of the NH3-N or NO2 standards.

• In 2009, DO standard violations were observed in the 15-minute in-situ data collected by the YSI sondes. For days in which the sondes were in operation, one or more of the measured DO levels at either the top or the bottom layer were below the daily instantaneous standard of 4 mg/L on 26%, 19% and 19% of those days at Buoys 409, 316, and 236, respectively. Likewise, daily averages calculated from the DO measurements made by the sondes at either the top or the bottom layer were below the daily average standard of 5 mg/L on 14%, 24% and 21% of the days in which the sondes were operated at Buoys 409, 316, and 236, respectively. Similar to previous years, these violations were more prevalent in the bottom waters than in the upper waters. However, compared to previous lower flow years, these data represent an improvement in water quality conditions (e.g., the frequency of violations was much higher during the low flow conditions observed in 2007).

Three Rivers System – 2009 Major Findings

• The water quality data collected in 2009 during the three full river surveys were generally similar to data collected in previous years. The data measured during the individual surveys were reflective of the predominant processes occurring in the river at that time of the year, including flow conditions, zebra mussel activities and inflow from Onondaga Lake and subsequent mixing.

• The average summer flow rate in 2009 was comparable to the long-term summer average, but it was much higher than what might be considered summer low flow conditions. As a result, the spatial trends of water quality parameters during the July and August surveys were similar in top and bottom waters and were overall less pronounced than those typically observed under lower flow conditions. Spatial trends observed during the September survey indicated stratified flow conditions and were consistent with trends observed during low flow surveys conducted in previous years.

• When compared with previous lower flow years (e.g., 2007) the water quality conditions in 2009 exhibited an improvement in terms of regulatory compliance.
