The Canadian Aquatic Biomonitoring Network (CABIN) program is used to assess the ecological health of wadeable streams by using data from a wide range of sites that are minimally impacted by humans to establish the natural variability of healthy benthic invertebrate communities within a large watershed. The data collected at these sites (known as “potential reference”) are used to build CABIN models, which can be used to evaluate the aquatic health at sites where there are concerns with the aquatic ecosystem (known as “test sites”). The differences between the benthic macroinvertebrates at the test site compared with the range of conditions found at similar reference sites provides information about the level of impacts within a watershed. CABIN models are used by government, Indigenous groups, industry, community groups, and others to assess aquatic ecosystems across the province.

CABIN models in BC are developed by the BC Ministry of Environment and Climate Change Strategy and Environment and Climate Change Canada and are available for data analysis on the CABIN website. Model documentation can be found here: https://gov.bc.ca/biomonitoring. However, note that online training and certification must be completed to access the CABIN database and to use the models (https://www.canada.ca/en/environment-climate-change/services/canadian-aquatic-biomonitoring-network.html).

Object Description


Comments: Polygons showing drainage basins for current BC CABIN bioassessment models

Column Name Short Name Data Type Data Precision Comments
ENV_CM_SYSID ENV_CM_SYD NUMBER 10 A system generated unique identification number
SUB_DRAINAGE_AREA_NAME SB_DRNG_NM VARCHAR2 60 The Water Survey of Canada Sub Drainage Area (WSCSDA) name, e.g., Headwaters Yukon, Hay.
MODEL_NAME MODEL_NM VARCHAR2 50 The name of the CABIN model, e.g., Okanagan (2018)
MODEL_YEAR MODEL_YEAR NUMBER 4 The year the CABIN model was developed.
FEATURE_AREA_SQM FEAT_AREA NUMBER 19 FEATURE_AREA_SQM is the system calculated area of a two-dimensional polygon in square meters.
FEATURE_LENGTH_M FEAT_LEN NUMBER 19 FEATURE_LENGTH_M is the system calculated length or perimeter of a geometry in meters.
SHAPE SHAPE SDO_GEOMETRY 1 SHAPE is the column used to reference the spatial coordinates defining the feature.
OBJECTID OBJECTID NUMBER 38 OBJECTID is a column required by spatial layers that interact with ESRI ArcSDE. It is populated with unique values automatically by SDE.
SE_ANNO_CAD_DATA BLOB 4000 SE_ANNO_CAD_DATA is a binary column used by spatial tools to store annotation, curve features and CAD data when using the SDO_GEOMETRY storage data type.
