Shediac and Scoudouc Rivers Water Quality Monitoring

Water quality monitoring began in the Shediac Bay Watershed during the provincial water classification program in the years 2000 and 2001. Basic physical measurements were then taken at the same sites from 2002 to 2006.  In 2007, additional parameters were measured (nitrate-nitrogen, total phosphorus and E. coli counts) on a monthly basis at each sampling site. The water quality monitoring is used to support the need for specific remediation actions and measure the effectiveness of our work. It is also used to complete detailed sanitary surveys and establish the status of our rivers.

Such monitoring helps determine if changes to the water quality have occurred and if sections of the stream or river remain suitable for aquatic life. It is of utmost importance to have accurate and continuous data of water quality parameters for the watershed. This allows for effective management strategies in the creation of remediation plans.

A database has been created to collect historical ABVBS monitoring data collected since 2000. This data set shows trends in water quality for sites monitored by the SBWA.

CABIN Macro-Invertebrate Survey

The Canadian Aquatic Biomonitoring Network (CABIN) is an aquatic biomonitoring program for assessing the health of fresh water ecosystems in Canada. The SBWA field team has been certified to conduct the sampling of invertebrates. Data on the habitat and species found were collected and sent to the Miramichi River Environmental Assessment Committee in a partnership project looking to increase CABIN data in Atlantic Canada.

All data from the CABIN surveys have been entered in the Canadian Aquatic Biomonitoring Network database on the Government of Canada website. Data can be shared with other groups and reports can be generated from the website.

The next step in this program is to compare our sites with reference sites in the area to determine stream health.

Water Testing in Shediac Bay

To measure improvements in water quality, Shediac Bay Watershed Association (SBWA) staff has initiated a water quality collection and testing program for waters of the inner bay. In-kind water analysis is performed by the Science & Technology Branch/Marine Water Quality Monitoring laboratory of Environment and Climate Change Canada.

The Data (2016) is summarized in the Water Sampling for the Shediac Bay report.



Community Aquatic Monitoring Program (CAMP)

Every summer since 2004, watershed and science-based community groups have been monitoring the health of ecosystems in estuaries throughout the Gulf Region, in partnership with the Department of Fisheries and Oceans (DFO).

The program consists of a single sweep of a 30-metre-long beach seine, at multiple sites, effectively gathering a representative sample of fish, shrimp and crab communities. The organisms caught are identified, counted and released. Other information is gathered on-site, such as water quality measurements, sediment samples and information on aquatic plants.

The SBWA studies 6 sites around the Scoudouc River estuary and 6 sites around the Shediac River estuary. In the past 12 years of sampling, communities in both rivers have remained relatively stable, indicating no major impacts on the health of these ecosystems.

Salt marshes

Salt marshes are an important ecosystem for the health of the Bay of Shediac. In 2016, the Association will survey the salt marshes around the Bay. We will Salt marshes are an important ecosystem for the health of the Bay of Shediac. In 2016, the Association will survey the salt marshes around the Bay. We will be examining vegetation and land use around the marshlands.

Two marshes, one in Pointe-du-Chêne and one in Grande-Digue, have been chosen for Bird Studies Canada’s Maritime Marsh Monitoring Program. This program aims to monitor all marsh birds, including waterfowl, migratory birds, and other wetland-associated species and their habitats. Monitoring these marsh birds helps us track long-term population trends and assess overall marsh health.

A report on the status of Shediac Bay marshes in will be available in winter 2016.

State of the Bay reports

Two important reports have been specifically prepared on the Shediac Bay Watershed.

In 2006 a report on the general state of the Bay and activities by the Association was published with support from the Environmental Trust Fund, the Department of Fisheries and Oceans and the Shediac Rotary Club. The report provides general information on the ecosystems and human activities in the Shediac Bay Watershed.

An Ecosystem Overview Report , prepared by the Department of Fisheries and Oceans in 2009, provides a good source of scientific and technical information about the Shediac Bay.
