Green Stream provides flood and weather early warning infrastructure.

Green Stream is a full flood and weather monitoring system provider for Public Safety, Environmental Professionals and Property Owners who want to protect people and property from flooding.  We offer everything from environmental sensors to software to real-time actionable data.

We believe that situational awareness from ground truth data is key to building flood resilience.
It is our mission to provide that data.

Flood Monitoring Network

Over 450 active deployments across 8 states as of June 2026.

With a large presence in Virginia and North Carolina, Green Stream is expanding its footprint as more communities learn about our flood monitoring capabilities.

Green Stream is deployed in coastal, plains and mountain environments, from dense urban neighborhoods to rural and remote locations.

About Green Stream

In 2017, Jim Gray and Karen Lindquist formed Green Stream. United by a concern about climate change and the increasing flooding in their area, they pooled their business and technology expertise to build an end-to-end affordable solution: remote sensors, co mmunications, cloud computing and data visualization. Since then, Green Stream has developed a growing customer base in flood-prone areas. We help communities build resilience with the end goal of better protecting people and property.

Today, Green Stream is a woman owned business with a team that works in partnership with customers and other solution providers to design, build, install and service solutions. We offer our own equipment and cloud services as well as third party equipment and platforms to meet our customers’ needs.
