Pictou County Water Quality data

Map and Visualize

The Pictou County Rivers Association (PCRA) started monitoring the water quality in the seven main rivers that run through our county in 2014. Approximately every two weeks from late May to early October, PCRA volunteers use portable water quality sensors to measure temperature, dissolved oxygen, pH and conductivity at 2 locations on each river, one just above the head of tide and one in the upper watershed. The program has been conducted every year since 2014 so we have 7 years of data collected and plan to continue the program in 2021. The data collected is compiled and summarized each year and the results compared to previous year’s results and Canadian Water Quality Objectives for the protection of fish and aquatic life. The PCRA acknowledges the technical and financial support provided by the Atlantic Water Network at St. Mary’s University and the NS Salmon Association's Adopt a Stream program which make it possible to conduct this program.

Data Collection Information

A WetPro Kit supplied by the Atlantic Water Network (AWN) at St. Mary’s University is used to collect the measurements. The portable YSI multiparameter probe is calibrated before each monitoring survey following the protocols established by the AWN.

Data Collection Processing

The data collected during the water quality monitoring surveys is entered onto field record sheets. Following the survey, the data is entered into an Excel spreadsheet. From there, the data is uploaded into the Atlantic DataStream.

Update to metadata


The measured pH of the Middle River site 1 was observed as abnormal. Three other locations along the river were tested after the abnormal pH reading was taken and all additional sites were noted as having a normal pH value for that particular area. An additional pH measurement was taken later in the day at the Middle River site 1 and also observed to be back to normal levels for that river therefore the cause of the alkalinity is unknown.

Thank you Noah D'Ascanio for assisting in formatting our field data for DataStream! Added new observations for 2018, 2019 & 2020 Season. pH values for 2019 not be used. We started with Sonde s/n 14H102448 (June 19th until Sept 15th) and received Sonde s/n 14H101221 for the Sept 29th & Oct 14th runs. There was an issue with the pH sensor (suspect faulty) that caused values that should not be used in the dataset, even values that were not negative are not valild/representative of normal or actual values. DO values for Sept 29th & Oct 14th were noted in % in the field and then calculated for data entry with the following formula on this website: We noted the water temperature and % to calculate the mg/L of DO.
