EXECUTIVE SUMMARY

This memorandum is one of a series of three memoranda that have been produced to describe fish habitat in the Red and Assiniboine rivers within the City of Winnipeg Ammonia Criteria Study Area. This document describes the water chemistry component of fish habitat, while two other memoranda describe the physical attributes and benthic invertebrate community. Data from all three memoranda will be used to explain fish distributions within the Study Area.

The objective of this study was to document the water chemistry of those portions of the Red and Assiniboine rivers within the Study Area. The focus of the study was to provide information to describe regional (zone) differences in habitats (macrohabitats) to contribute to explaining potential regional differences in fish distributions.

Three surveys were conducted to describe water chemistry in the Red and Assiniboine rivers. The first sampling period took place during February - March, 1999, the second during July, 1999, and the third during September, 1999. A water chemistry sampling program was developed using the segments previously designated by the physical habitat surveys. The Red and Assiniboine rivers had been divided into five major zones, which were divided further into 86 and 30 segments, respectively.

For all three sampling periods, water chemistry data were collected at each of the fish sampling sites. All tributaries to the Red and Assiniboine rivers in the Study Area, and the mixing zones downstream of the Water Pollution Control Centre (WPCC) effluent outfalls, were also sampled during the second and third periods. Water chemistry data are presented by river segment within each of the major zones.

Water chemistry data collected in the Red and Assiniboine rivers during the open water period of 1999 were gathered under conditions of very high stream discharge. During the autumn sampling period, stream discharges of both rivers were the highest on record. In winter, ammonia was elevated above background concentrations at sites downstream of the WPCCs, with the highest concentrations occurring in Zone 3. Elevated ammonia concentrations downstream of the WPCCs were less evident in summer and autumn, likely due to the breakdown of ammonia by biological processes. The Manitoba Surface Water

i City of Winnipeg Ammonia Criteria Study Fish Habitat - Water Chemistry Data Draft - January, 2000

Quality Objective (MSWQO) for dissolved oxygen for the protection of cool water species is 47 % saturation (Williamson 1988). All dissolved oxygen measurements made in the Red and Assiniboine rivers in winter, summer, and autumn, 1999, met the MSWQO guideline, with the exception of a single measurement at Segment 59 (within the NEWPCC mixing zone) on July 13.

1.0 INTRODUCTION

Fish distribution, abundance, and health are dependent on the quality and quantity of habitat. Fish habitat is generally a function of physical (i.e., substrate, water depth, water velocity, and riparian conditions), chemical (i.e., dissolved oxygen, turbidity, water temperature, pH, and ammonia concentration), and/or biological (i.e., benthic invertebrate community abundance and composition) factors. To explain differences in distribution, abundance, and condition of fish inhabiting various locations, we must have an understanding of how habitat parameters differ among those sites.

This technical memorandum is one of a series of three memoranda that have been prepared to describe fish habitat within the City of Winnipeg Ammonia Criteria Study Area (Figure 1) and contribute to the understanding of fish distributions in the Red and Assiniboine rivers. This document describes the water chemistry component, including measurements of pH, conductivity, turbidity, dissolved oxygen, water temperature, and ammonia concentration. A description of the physical attributes and biological components of fish habitat in the Red and Assiniboine rivers within the Study Area are provided in two other technical memoranda entitled:

Fish Habitat Technical Memorandum #FH 01: Physical Data to Characterize Fish Habitat in the Red and Assiniboine Rivers.

Fish Habitat Technical Memorandum #FH 02: Benthic Invertebrate and Sediment Data to Characterize Fish Habitat in the Red and Assiniboine Rivers.

The primary objective of this portion of the study was to document the basic water chemistry of those portions of the Red and Assiniboine rivers that lie within the Study Area for the City of Winnipeg Ammonia Criteria Study. The focus of the study was to provide information to describe regional (zone) differences in habitats (macrohabitats), which would assist in explaining potential regional differences in fish distributions.

2.0 METHODS

2.1 STUDY AREA

The study area for the City of Winnipeg Ammonia Criteria Study is shown in Figures 1 - 3. The study area is divided into five major zones, which are divided further into segments. Two additional zones were used as controls for some components of the Ammonia Criteria Study. A description of the extent of each zone is as follows: C Zone 1A - extends between Ste. Agathe and St. Adolphe on the Red River and was used as a control area for the summer and autumn sampling periods; C Zone 1 - extends from St. Adolphe to the South End Water Pollution Control Centre (SEWPCC) on the Red River; C Zone 2 - extends from the SEWPCC to the North End WPCC (NEWPCC) on the Red River; C Zone 3 - extends from the NEWPCC to the St. Andrews Locks near the town of Lockport on the Red River; C Zone 3A - extends from the St. Andrews Locks at Lockport to downstream of the City of Selkirk on the Red River; C Zone 4 - extends from the West End WPCC (WEWPCC) on the Assiniboine River to the confluence of the Assiniboine and Red rivers; and, C Zone 5 - extends from Headingley to the WEWPCC on the Assiniboine River.

2.2 WINTER SAMPLING

Water chemistry data were collected from February 24 to March 11, 1999 as part of the Fish Habitat component of the Ammonia Criteria Study. Water chemistry data were collected at each site at which a gill net was set, using the holes drilled through the ice for the nets. Measurements were made at both ends of each gill net to provide information on any variation in ammonia concentrations along the length of the net.

Measurements of pH, conductivity (corrected to 25 EC), turbidity, dissolved oxygen, and temperature were made with a Horiba® U-10 Water Quality Checker (Horiba® Ltd., Kyoto,

2 City of Winnipeg Ammonia Criteria Study Fish Habitat - Water Chemistry Data Draft - January, 2000

Japan). At selected sites, measurements were made near the river bottom and at the bottom edge of the ice (referred to as surface measurements). At all other sites, measurements were made 1 m below the bottom of the ice.

Ammonia analysis was performed on 10 ml aliquots of water collected from the river surface. When sampling through ice, the water was mixed vertically to avoid contamination by meltwater from the ice. Immediately upon collection, each sample was fixed for ammonia analysis with a Palintest® reagent system (a tablet reagent system based on the indophenol method). Fixed samples were stored in the dark until analysed at the end of the day with a Palintest® 5000 spectrophotometer (Palintest® Ltd., Tyne & Wear, England). For samples that required dilution, dilution was performed in the field, by adding aliquots of sample into pre-measured volumes of tap water. The tap water was analysed to ensure that it contained no measurable ammonia.

Unionized ammonia for all samples was calculated using the following equation:

(0.09018+(2729.92/(273.16+temperature(EC)))-pH) NH3 (mg NH3/L) = total ammonia (mg/L)/10 +1)

2.3 SUMMER AND AUTUMN SAMPLING

Water chemistry data were collected from July 8 to 27 and from September 8 to 19, 1999 as part of the Fish Habitat component of the Ammonia Criteria Study. Measurements were made from an anchored boat.

As in the winter sampling, measurements were made at each gillnet site, but only one set of measurements was made at each site, at a point near the middle of each net. All tributaries to the Red and Assiniboine rivers in the study area were sampled. Measurements were made in the mixing zones downstream of the Water Pollution Control Centre (WPCC) effluent outfalls to determine the spatial extent of elevated ammonia levels within the mixing zones.

Measurements of pH were made at the water’s surface with a handheld Oakton® Model 35624-35 pHWand®. Turbidity was measured at the surface with a Hach® Model 2100P portable turbidimeter (Hach® Company, Loveland, Co, USA). All other in situ

3 City of Winnipeg Ammonia Criteria Study Fish Habitat - Water Chemistry Data Draft - January, 2000

measurements were made at mid-depth. Dissolved oxygen was measured with a YSI Model 95 handheld meter (YSI Corporation, OH, USA). Conductivity (corrected to 25EC) and temperature were measured with a YSI Model 30 handheld meter.

Surface samples were collected and immediately preserved for ammonia analysis using the same Palintest® system used in the winter sampling program.

2.4 SAMPLING WITHIN THE MIXING ZONE OF THE NEWPCC

As part of the Fish Behaviour component of the Ammonia Criteria Study, sampling within the mixing zone of the NEWPCC effluent outfall was performed in March and October, 1999. All measurements were made from an anchored boat.

Measurements of dissolved oxygen, temperature, and pH were made at various depths using the Horiba® U-10 meter. Water samples were collected for ammonia analysis from discrete depths with a 1.5 L Kemmerer sampler. Aliquots of each sample were fixed for ammonia analysis with the Palintest® system.

3.0 RESULTS AND DISCUSSION

Table 1 summarizes the ammonia data collected from Zone 1A to Zone 5 in winter, summer, and autumn of 1999. Water chemistry data collected as part of the Fish Habitat component of the Ammonia Criteria Study are presented in tabular format by river segment within each of the major zones. Maps to illustrate where data were collected are provided in Figures 4 - 26. Water chemistry data from sampling in the mixing zone of the NEWPCC have been presented in Lawrence (1999) and Lawrence and Barth (2000). The water chemistry data collected in these studies are presented in Appendix 1 (study conducted in March, 1999) and Appendix 2 (study conducted in October, 1999) of this report.

Water chemistry data collected in the Red and Assiniboine rivers during the open water period of 1999 were collected under conditions of very high stream discharge. During July, discharge in the Red and Assiniboine rivers (provisional weekly data provided by Manitoba Conservation, Water Resources Branch) was approximately 2.5 and 3 times, respectively, the historical mean monthly mean discharges (Figures 27 - 29; Environment Canada 1991). During the autumn sampling period, stream discharge of the Red and Assiniboine rivers (provisional weekly data provided by Manitoba Conservation, Water Resources Branch) were the highest on record (Figures 27 - 29; Environment Canada 1991).

Ammonia concentrations were highest in winter, which is expected, as cold temperatures and reduced light in the water column during winter reduce the abundance and activity of bacteria and phytoplankton (algae in the water column), which remove ammonia from the water. In winter, ammonia was elevated above background concentrations at sites downstream of the WPCCs, with the highest concentrations occurring in Zone 3. Elevated ammonia concentrations downstream of the WPCCs were less evident in summer and autumn, likely due to the uptake of ammonia from the river by biological processes.

Three sets of measurements taken in Zone 3 on March 8, 1999 showed higher than anticipated ammonia concentrations. The higher values occurred at Segment 72 (1 measurement) and Segment 74 (both measurements). Under the pH and temperature conditions at these sites at the time, the unionized ammonia concentrations were 0.0246 mg/L at Segment 72 and 0.0223 mg/L and 0.0190 mg/L at Segment 74. Other winter

5 City of Winnipeg Ammonia Criteria Study Fish Habitat - Water Chemistry Data Draft - January, 2000 measurements made in Zone 3 were lower.

The Manitoba Surface Water Quality Objective (MSWQO) for dissolved oxygen for the protection of cool water species is 47 % saturation (Williamson 1988). All measurements made in the Red and Assiniboine rivers in winter, summer, and autumn, 1999, were above this value, with the exception of a single measurement of 3.78 mg/L (46% saturation), which occurred at Segment 59 (within the NEWPCC mixing zone) on July 13.
