Trend Insight
Odor reports tend to peak in the late afternoon and evening hours, likely due to temperature inversions that trap ground-level air. Landfill and farm odors are the most commonly reported types across both cities.
Your Neighborhood,
Your Air Quality
OdorWatch is a community-powered tool to help track and share information about unpleasant outdoor smells in real time. Whether it's a nearby landfill, a farm, or an unknown source — your reports help everyone in Roseville and Rocklin stay informed.
Report to the Authorities
OdorWatch helps you track smells with your neighbors — but for official investigations and corrective action, use these city and county resources.
Tip: Filing a report with OdorWatch helps your neighbors stay informed. Filing a report with the city or county creates an official record that can trigger inspections and corrective action. We recommend doing both when you experience a significant odor event.
