title: CIMP 180_ The impact of wildfire on diverse aquatic ecosystems of the NWT

description: During the summer of 2014, the southern Northwest Territories (NWT) experienced an unprecedented fire season, with a burn fingerprint that spread across two ecoregions (the Taiga Plains and Taiga Shield), and a landscape that is underlain by mosaic of permafrost coverage, vegetation type, and previous fire history.  Our study was conducted across the Dehcho, Wek’èezhii, and Akaitcho Geographic Regions, which encompass the most significantly burned areas from the 2014 fire season.  Within these regions, we examined water quality across a series of 50 catchments that varied based on within-catchment fire extent, ecoregion (Taiga Plains vs. Taiga Shield), and within-catchment characteristics such as wetland extent. This sampling scheme – which covers as significant a range of landscape variability as possible – is allowing us to tease apart the effects of wildfire from other landscape variables that cumulatively impact aquatic ecosystem health. We find that the effects of wildfire on stream water chemistry are relatively weak when measured at stream outlets, but that these effects can teased apart from other, key landscape attributes with the use of multivariate analyses and a large sample size. However, we do find transient changes in water quality immediately post-fire, and changes in pore water chemistry and hydrologic parameters within catchments affected by wildfire. Future work should examine long term fire-induced changes within catchments, and focus on determining the effect of wildfire during years that are relatively wet.

title: Woodstock First Nation Climate Monitoring Program

description: The Woodstock First Nation Climate Monitoring Program aims to continuously sample the streams and lakes of our elders before us and those who surround the Wolisataquey territory for safe fishing and swimming. The sampling is conducted by portable sensors that lay just below the water’s surface and sends the data to a device in which the data can be saved and reviewed.  
The team of the Woodstock First Nation Climate Monitoring Program also promotes and encourages both youth and elders to play an active role in our project and to understand the importance of monitoring the health of our waters surrounding us.
description: A YSI multiparameter probe (Professional Plus) is used to collect water temperature, dissolved oxygen, pH, conductivity and oxidation reduction potential data at all river and stream sampling locations just below the water surface. Sensors for dissolved oxygen, pH and conductivity are calibrated every day before sampling and data are recorded on paper and logged on the YSI. Observations and notes are also recorded on paper field sheets. Field data are collected several times through the open water season.
description: Logged values are compared to field sheets before uploading to confirm consistent and complete record keeping.

title: Canaan-Washademoak Watershed Association Water Quality Dataset

description: CWWA has been monitoring water quality for over 20 years; we have followed the Province of New Brunswick’s methods for monitoring *B and E. Coli, installed data loggers to measure temperature, and established 23 long-term monitoring sites.  We attempt to sample every two years, and have selected a subset of 10 monitoring sites based on availability of funding for our work.
description: A YSI probe is used to collective data on physio-chemical parameters at all sampling stations (n=10 to 23).  A YSI 9500 is used to test to additional chemical parameters, including nitrate, nitrite, and organophosphorus.  Hoskins Tidbit data loggers are installed at 10 sampling stations in June and removed in October to monitoring water temperature (interval = 30 minutes).  

1997-2018 samples were collected and submitted to Provincial lab for analysis (1997-2016); after Provincial lab class, (2017-) samples were submitted to RPC laboratory in Fredericton, NB.

title: KananaskisRiver_ENSC

description: The University of Calgary Environmental Science Program has an annual field school in the lower Kananaskis Valley, SW Alberta, that occurs in the first week of September.  At several river sites, largely consistent among years, senior students collect data on water chemistry, macroinvertebrates and hydrology.  Water chemistry data are obtained using field and lab instruments by the students and by a lab technician. These annual data are analyzed each year by students to assess human impacts associated with recreation in the valley.
description: At each site, physio-chemical parameters were measured with replication using individual hand-held meters. Grab samples following standard protocols were collected for geochemistry analysis (one 500 mL bottle, field filtered with 0.45 micrometer cellulose nitrate membrane), alkalinity (one 500 mL bottle, unfiltered) and microbiology (four 125 mL bottles, unfiltered). 

Samples were transported back to the field station in coolers with ice packs. Subsamples were collected in scintillation vials, from the field-filtered geochemistry sample, for major ion analysis. At the field station students used Hach spectrophotometers to analyzed for sulphate (Method 8051 SulfaVer 4 Method Powder Pillows), ammonium (Method 8155 Salicylate Method Powder Pillows), ortho-phosphate (Method 8048 PhosVer 3 (Ascorbic Acid) Method Powder Pillows), and silica (Method 8185 Silicomolybdate Method Powder Pillow). Alkalinity was measured using a Hach digital titrator (Method 10244 Phenolphthalein and Total Alkalinity), while samples collected for microbiology were analyzed for total coliform and Escherichia coli (recently Colilert test). Major ions where determined by ion chromatography at the Environmental Science Laboratory (University of Calgary).

Prior to field work, students were trained on the use of hand-held meters, including calibration, and of field spectrophotometers using standards.  All field and lab work by students was supervised by staff with expertise in water chemical analyses.
description: Data were reviewed and analyzed each year.  Potentially anomalous values were checked against original values or field notes and corrected if errors were detected.  Otherwise, the 'anomalous' values were retained.

title: Bragg Creek Water Quality Monitoring

description: The Bragg Creek Water Quality Monitoring Collective group (comprising 44 volunteer citizen scientists) collected grab samples along Bragg Creek from 2005 to 2019. Each sampling period covered the first “weekend” of the month (Friday through Monday). Six sites were monitored five times per year (May through September). The resulting dataset provides baseline conditions for the temporal and spatial variations in gradients of water quality in Bragg Creek, measured in six water quality traits and stream level, and is sufficiently long for among-year trends to emerge. With each passing year, the additional data allow for a more robust statistical analysis of water quality changes. Our project is succesful thanks to our volunteers, to Ralph Cartar's dedication, to the Elbow River Watershed Partnership, turbidity meter from The City of Calgary, conductivity meter from Bob McAlpine, and titration of our stream gauge from Alberta Environment)

With each passing year, the additional data allow for a more robust statistical analysis of water quality changes. This is the equipment used for monitoring:
Meters currently in use (2020): 
-Hach 2100P Turbidometer (0-9 NTUs (±2%)) 
-Hach Pocket Colorimeter II (Nitrate; Cadmium Reduction Method, 0.4-30 mg/L) 
-Hach Pocket Colorimeter II (Phosphorus; Reactive (Orthophosphate); Ascorbic Acid Method, 0.2-3.0 mg/L) 
-Hanna HI 96753C Chloride Meter (0-20 mg/L (±6% of reading @ 25°C)) 
-Hanna HI 9033 Conductivity Meter (0-1999 (±1%))
description: The key modifications to data came in 2 ways:

1. All measurements of turbidity, N, P, Cl, and conductivity reported are an average of 3 readings. These weren't 3 independent preparations of the same water sample. They were 3 readings of the same preparation of the same sample. That is, they reduce measurement error, not sampling error.

2. Some "zero" readings for kits with high sensitivity were discarded, because they represent a failure in the process, not a true zero.

title: Petite Riviere Lakes and Headwaters Dataset 

description: The Petite Riviere Water Quality Program has added this secondary complementary program to monitor water quality within the headwaters of Millipsigate Lake, Hebb Lake, and Minamkeak Lake, and within each of the lakes, to assess and mitigate harm to the environment and aquatic organisms within the watershed. This program is funded by the Habitat Stewardship Program.
description: A YSI Pro-DSS and Pro Plus are used to collect the water's physical characteristics in situ. The probe's pH and conductivity are calibrated monthly, while DO% is calibrated once before each field day, and twice-more throughout the sample collection. All chemical samples are sent to an accredited laboratory for analysis, where samples are also subject to the lab's QAQC. Samples are held on ice until delivery to the lab - within 24 hours of collection.

title: Blue Mountain Birch Cove Lakes Water Quality Baseline data

description: In April 2021, a team of volunteers conducted a water quality survey by canoe of 21 lakes within the conceptual boundary of the Blue Mountain Birch Cove Regional Urban Wilderness Park.  Variables measured included Secchi depth (a measure of turbidity), dissolved oxygen, conductivity, pH and total phosphorus.  Vertical profiles indicated that all lakes were well mixed from surface to bottom at the time of sampling.  Mean values of each variable were calculated for each lake.  Secchi depths ranged from 1.5 to 3.0 m, dissolved oxygen ranged from 80 to 100 %, conductivity ranged from 14 to 187 μS/cm, ph ranged from 3.61 to 6.12 and total phosphorus ranged from 4 to 9 μg/l.  The highest values for conductivity occurred in the lower part of the Kearney Run watershed and indicate the addition of road salt and other pollutants from surrounding development.  The lowest values for pH can most likely be attributed to widespread acid precipitation during the latter part of the twentieth century.  Overall, the water quality of the lakes appears excellent but continued monitoring is recommended, especially in the lakes in the lower part of the Kearney Run Watershed such as Susies, Quarry, Washmill and Kearney lakes which are currently the most affected by development.
description: Vertical profiles and surface sample water were collected using canoe platforms.  Physical data collected using YSI Professional Plus multi-probe equipped with a 30 m cable but lacking pressure so sample depths estimated by wireout.  The sample dates were windy so station keeping difficult and depths questionable.

title: NSRBC Water Quality Data

description: The North Saskatchewan River Basin Council (NSRBC) is a non-profit organization that has formed to support and direct the implementation of the Source Water Protection Plan for North Saskatchewan River Watershed. As part of the Lake Winnipeg Basin Fund, the NSRBC partnered with 3 other local watersheds to monitor water quality trends for upper tributaries of the Saskatchewan River System. Water quality field data is collected at each site along with water samples, which are sent for lab analysis. The goal of this project is to collect data on nutrient loading in the Saskatchewan River Basin and increase public awareness of the effects from nutrient loading to our river systems.
description: The Myron L UltraPen models PT2 and PT4 are used to collect pH, temperature, and conductivity in the field. To collect water samples for future lab analysis, a pole-mounted 1-litre sampler bottle is used. These samples are chilled and sent off for lab analysis on additional parameters.

title: Ghost Watershed Water Quality Monitoring Program

description: The purpose of the multi-year GWAS Water Monitoring Plan is to provide knowledge and a database of information about the health of the lotic aquatic systems within the Ghost Watershed. Monitoring changes over time is an important aspect of protecting a watershed. Monitoring of watershed health following the CABiN (Canadian Aquatic Biomonitoring Network) protocol is a recommendation in the Ghost River State of the Watershed Report (2018). The data collected will augment existing information and is intended to assist public land managers and other organizations tasked with water management responsibilities to better manage our water resources. It will also help GWAS identify high priority sites for future restoration and provide baseline data for future state of the watershed reporting.
description: Water properties were either recorded on-site using a YSI-DSS multimeter* or samples were collected in specific plastic containers provided by the analytical laboratory depending on the test**:  
-	pH*

title: Charlottetown Harbour Water Quality Monitoring

description: Holland College conducts annual sampling for the City of Charlottetown to monitor the water quality of the City's Harbour for recreational use. Enterococci testing was conducted by PEI Analytical Laboratories.
description: Samples were collected at each site using sample bottles obtained from the PEI Analytical Laboratory (Faecal Sample bottles).  Collected samples were kept on crushed ice for delivery to the lab on the same day that collections were made. The PEI Analytical Lab had been previously notified that the samples would be coming in that day, to allow them to prepare the media prior to the samples arriving.  They were tested for Enterococci, which is used as a primary indicator of recreational water quality (Guidelines for Canadian Recreational Water Quality, #rd ed. 2012).

title: LakeWatch Water Quality Data

description: The Alberta Lake Management Society accepts requests from citizen scientists across Alberta to have their lake monitored as part of the LakeWatch program. Volunteers often contact the Alberta Lake Management Society due to concerns around eutrophication, harmful algal blooms, watershed developments, biodiversity monitoring, and for the early detection of aquatic invasive species. If accepted into the program, a lake will be monitored 4-5 times throughout the open water season: once in June, once in July, twice in August, and once in September. ALMS hires and trains field technicians in proper sampling techniques and it is these field technicians who arrange the sampling trips with the citizen scientists. At the lake, the citizen scientist’s role is to transport the technicians around the lake on a boat and to assist with sampling. The field technicians provide all necessary sampling equipment, support the volunteers in training, and oversee sample preservation, handling, and shipment. This program is free of charge for individuals hoping to collect water quality data from their lake. This program is made possible with the support of various funders, including the Government of Alberta, and would not be possible without hundreds of hours of volunteer time by lake stewards.
description: Data is collected as both a profile and a composite sample. For profiles, Hydrolab multiparameter sondes are used to measure depth, temperature, conductivity, pH, dissolved oxygen, and redox potential at one location on the lake. Samples are recorded in increments of 0.5 or 1.0 meters. The multiparameter probes are calibrated on a weekly basis, with the exception of the RO meter which is calibrated monthly. At this location, a Secchi disk depth reading is also collected. The composite sample is comprised of water collected from ten locations around the lake. These samples are collected from the lake’s euphotic zone using a one-way foot-valve attached to weighted tubing. Samples collected using the composite method are ultimately poured off into various bottles to be tested for various parameters. Nutrients and general water chemistry are analyzed by Maxxam Analytics whereas total recoverable metals are analyzed by Innotech. Chlorophyll-a samples are filtered by field technicians before being sent for analysis.

Biological data is also collected through the LakeWatch program. Biological data includes a zooplankton haul at the lake’s profile site, samples collected to detect spiny water flea and Dreissenid mussels, and a sample collected as part of the composite for phytoplankton taxonomy. 

A duplicate true-split total phosphorus sample is collected once per season at each lake to act as a quality control.

title: Measurements of Total Phosphorus within the Lake Mattatall and its watershed

description: The objective of the Mattatall Lake Stewardship Association is to support all measures of improving the water quality of Mattatall Lake and to protect the surrounding watershed. The Association endeavours to understand nutrient levels that may cause algal blooms, and to use this knowledge to protect water quality into the future.  The Association will share knowledge and encourage best environmental practices with the residents of Mattatall Lake and surrounding watershed stakeholders. Through research and advocacy, the Association will help prevent similar problems in other parts of Nova Scotia. Water samples were collected from Mattatall Lake and its adjacent streams using appropriate water sampling bottles and were delivered to a certified laboratory for analysis of total phosphorus.
description: Measurements of total phosphorus were made by the Environmental Services Laboratory of the Nova Scotia Health Authority (Halifax, Nova Scotia). Surface water samples from streams were collected using sample bottles provided by the laboratory and depth samples within Mattatall Lake were collected using a horizontal Van Dorn bottle before sub-sampling to the laboratory bottles. Efforts were made not to include sediment. Samples were kept cool until delivered to the laboratory generally within 1-2 days.

title: Aquatic Habitat Inventory Water Chemistry Data

description: The Aquatic Habitat Inventory contains lake, river and stream survey data collected from the 1950s to the 1990s. These surveys were conducted to acquire basic knowledge of the chemical, physical and biological characteristics of Ontario’s lakes, rivers, and streams to aid in watershed planning, aquatic habitat conservation and fisheries management.
description: For information on how data were collected please visit: https://www.ontario.ca/document/aquatic-habitat-inventory-survey-manual
description: The official name of the lake, river, or stream approved by the Ontario Geographic Names Board is used as the Monitoring Location Name. Where there is no official name, the unofficial name is used and labeled as such (E.g., Patricia Lake (Unofficial Name)). 

For some waterbodies there were monitoring site-specific coordinates provided. To account for any method inaccuracies or transcribing errors, a horizontal accuracy measure of 500 m is assigned to these site-specific location coordinates. In all other cases the monitoring location is indicated by general waterbody coordinates, locating either the mouth of a stream or a central point in a lake. A horizontal accuracy of 2000 m is assigned to these waterbody coordinates to account for the formerly mentioned method inaccuracies as well as the fact there may be multiple sampling sites within the lake or stream.

description: Temperature Data are DAILY Mean (for DAILY Min and Max visit http://rivtemp.ca/)

The instruments used for water temperature measurement vary from station to station. However, Hobo Pendant (Onset) models are widely used at these stations. Some stations are monitored only during the summer months while others are maintained year-round.
description: The daily data were validated according to a series of automated procedures applied to the observed data (validations are made on the amplitude of the measured values and on the fluctuations between two observations) and to the calculated daily values (verification of the number of observations kept and of the average fluctuations of the measurements during the day). Despite these validation procedures, some erroneous data may still be present. RivTemp and its partners assume no liability for any action, error or omission, use, misuse or result arising from the use of this data or parts thereof.
