Scripts to prioritize assessment/remediation of potential barriers to fish passage, based primarily on stream gradient.

bcfishpass

bcfishpass is a collection of scripts to create and maintain an aquatic connectivity / fish passage database for British Columbia to:

• track known barriers to fish passage (eg dams, waterfalls)
• work with assessed BC Provincial Stream Crossing Information System (PSCIS) crossings
• model potential barriers to fish passage (stream gradient, road/rail stream crossings)
• model passability/accessibility of streams based on species swimming ability
• model streams with potential for spawning and rearing activity (for select species)
• report on habitat/connectivity based indicators to support prioritization of assessment and remediation
• support mapping in office and field via a comprehensive QGIS layer file

See the Documentation for details.

General requirements

• bash
• GDAL (tested with v3.6)
• a PostgreSQL / PostGIS database (tested with v14/v3.3)
• Python (tested with v3.11.0)
• bcdata
• fwapg
• bcfishobs

Setup / Usage

bcfishpass is a collection of shell/sql/Python scripts. To download and use the latest:

git clone https://github.com/smnorris/bcfishpass.git
cd bcfishpass

Install required tools using your preferred method. For local development, conda can be simplest:

conda env create -f environment.yml
conda activate bcfishpass

A Docker image is also provided:

docker pull ghcr.io/smnorris/bcfishpass:main

If the database you are working with does not already exist, create it:

createdb bcfishpass

All scripts presume that the DATABASE_URL environment variable points to your database. For example:

export DATABASE_URL=postgresql://postgres@localhost:5432/bcfishpass

Load FWA:

git clone https://github.com/smnorris/fwapg
cd fwapg
make --debug=basic

Load/run bcfishobs:

git clone [e-mail]:smnorris/bcfishobs.git
cd bcfishobs
make --debug=basic

Create db schema:

jobs/db_setup

Load source data:

jobs/load_static                     
jobs/load_monthly
jobs/load_weekly
jobs/load_modelled_stream_crossings

Run the model:

jobs/model_stream_crossings    # (optionally - this is only needs to be run on the primary provincial bcfishpass database)
jobs/model_prep
jobs/model_run

Backups

Backup strategies will vary but it can be useful to dump the entire database to file.
This appends the date and commit tag date to the file name:

    pg_dump -Fc $DATABASE_URL > bcfishpass.$(git describe --tags --abbrev=0).$(date +%F).dump
