Elk River Alliance's 2025 Community-Based Monitoring Hydrometric Report
Download: 2025_hydro_report_w_review.pdf
The Elk River Alliance’s hydrometric program monitors temperature and flow variations over time, creating datasets to model the impacts of climate change and land use on the Elk River and its tributaries. Ongoing logging enables long-term assessment of changing conditions while accounting for daily, weekly, and monthly fluctuations. This information is critically important for monitoring the health of aquatic habitat for wildlife species, including SARA-listed Westslope Cutthroat Trout (WCT). This data also helps develop water budgets within the Elk Valley, giving decision makers and land managers the information needed for long-term planning for fisheries, climate change adaptation and flood mitigation.
ERAs hydrometric program consists of five level logger stations and 17 temperature logger sites located on tributaries throughout the Elk River Watershed. Originally, 19 temperature loggers were installed, with two temperature logger stations being upgraded to level loggers in 2024, which also collect temperature data.

| Data collection info | Station equipment is industry-standard, and stage, discharge, and benchmark measurements are conducted in accordance with BC RISC standards (Ministry of Environment and Climate Change Strategy, 2018). ERA aims to complete two benchmark surveys and at least seven stage/discharge measurements at each hydrometric site per year. Temperature loggers are visited 1-2 times a year to download data and to complete any necessary maintenance. |
| Data processing | Level logger data, stage and discharge data, field notes, and photos are uploaded to Aquarius. This software platform allows management, analysis, and export of water data. Initial data quality assurance and quality control (QA/QC) is conducted in-house by the Elk River Alliance. Further preliminary review of hydrometric data was conducted by MacHydro. All initial review of temperature data is conducted in-house using HOBOware, Microsoft Excel and R. Data is then uploaded to be publicly available through the Columbia Basin WaterHUB. |
