WELL OWNER’S REFRESHER: TAKING CARE OF YOUR GROUNDWATER VIDEO
This video, put together by Montana State University Extension Water Quality is a great resource for homeowners new to using a well and septic, or a great refresher for anyone. Check it out here:
GOING SWIMMING? EAST GALLATIN RECREATION AREA WATER QUALITY
A resource is available for you to check on the water quality at the recreation site, and will be updated once a month. Click here for the information.
NEW RESOURCE: IRON AND IRON BACTERIA FACT SHEET
The GLWQD has just published a new fact sheet on iron and iron bacteria. If you think you may have iron in your well water, or iron bacteria present in your water system, read more about it here.
GALLATIN COUNTY WATER SUPPLY OUTLOOK
Gallatin County Extension is now compiling monthly water supply outlook reports for the Gallatin County region, reporting data from nearby NRCS SNOTEL sites and USGS stream gages and comparing it to longer term averages. The reports also include the NRCS Surface Water Supply Index and the NOAA’s Drought Monitor maps. Online reports can be found here.
Gallatin County Emergency Management provides comprehensive flood preparedness information, including how to prepare for and stay safe during a flood.
Gallatin County Planning is currently working with the Federal Emergency Management Agency (FEMA) and Montana DNRC to update Flood Insurance Rate Maps for the West Gallatin River and Bozeman Creek and its tributaries. The finalized maps may be used by lenders, insurance agents, county government, property owners, and developers to determine areas of flood risk. Gallatin County GIS has put together an interactive map viewer of the update for visualization and planning (non-regulatory) purposes. Users are advised that the interactive map may not align exactly with the official FEMA Flood Insurance Rate Maps, which will be used by lenders.
Current floodplain boundaries can be viewed on the Planning Department’s web mapper. Please select one or more ‘FEMA layers’ in the upper right. Layer display is scale-dependent.

ADVENTURE SCIENTISTS RELEASES MICROPLASTICS INITIATIVES FINAL REPORT
Bozeman-based Adventure Scientists has released a final report outlining the findings of their Global and Gallatin Microplastics Initiatives. GLWQD was a member of the Gallatin Microplastics Coalition and provided guidance on project design and implementation for the project. Microplastics, defined as plastic particles less than 5mm in size, are gaining attention as a contaminant of concern in water bodies globally. The Gallatin initiative surveyed contamination in the Gallatin River Watershed, and is the only watershed-scale study of microplastic pollution conducted to date with seasonal sample collection over multiple years. Read the report here.
CHANNEL MIGRATION ZONE MAPS AND REPORTS COMPLETED FOR EAST & WEST GALLATIN RIVERS
Tony Thatcher of DTM consulting and Bozeman geomorphologist Karin Boyd have completed channel migration zone (CMZ) maps and reports for the East and West Gallatin Rivers. CMZ mapping is based on the understanding that rivers are dynamic, moving laterally across their floodplains through time, and is a science-based tool that can be used to help the public, landowners, and decision makers develop an understanding of river dynamics, along with the inherent risks and benefits associated with those processes. The reports are moving to a new home on the Montana State Library CMZ webpage, and should be available there soon!
