Water agencies are under growing pressure to collect more data, share it publicly, and report it to regulators — often with lean staff and legacy systems. Our purpose-built See Upstream Water Data Portal brings sensor data, maps, and dashboards together in one place for engineers, program managers, and the public alike.
See Upstream is Tierra Plan’s water data platform. A configurable, agency-ready foundation for monitoring surface water conditions, tracking groundwater, sending flood alerts, and providing data to the public.
Interactive web maps can be customized to match your unique needs. Maps display your sensors by type, including real time data, current and aggregate conditions, and flood risk.
Real-time and historic data can be mapped, charted, and downloaded online. Maps, charts and tables are colorful and dynamic, indicating current stream flows, reservoir conditions, and groundwater data.
We can integrate sensor data from diverse systems data from USGS, Aquatic Informatics, Hydstra, Xylem’s Hydrosphere, LoggerNet, Mesonet, CIMIS, and other systems. Our scalable water portals support unlimited sensors and sources, bringing streamflow, stage, precipitation, reservoir, and temperature and other data together in one platform.
Our water data portal websites are responsive: they are designed for desktop and mobile screens. We avoid the complexity of native apps with a single web application that lets users explore your water sensor data on any device.
See Upstream can help your agency meet SB88, Sustainable Groundwater Management Act (SGMA), Open and Transparent Water Data Act, and AB1755 Open Data requirements by making your hydrologic sensor data publicly available online.
Manage your sensor configurations and locations through a secure administrator portal. Add and remove sensors, customize dashboard layouts, and define your own stream flow thresholds.
Alert users through visualizations and notifications when stream flow conditions approach flood risks, or when low-flow or low-level conditions could affect water health.
Every agency has unique needs and their own identity. We customize your water portal design and user experience to best suit your data, branding, and desired user experience.
We provide hands-on guidance to organize and optimize your portal’s design, content, and data, ensuring your portal is practical, intuitive, and informative.
We can host your water portal or help with deployment for hassle-free launch. We also provide technical support, features updates, and bug fixes.
Explore what we can do together through examples of water data portals we’ve created for our clients.

We worked with the Santa Clara Valley Water District to design and build a public-facing surface water data portal that allows visitors to view real-time sensor data, view flood watch alerts and forecasts, sign up to be notified of flood alerts, and graph and export data.
Zone 7 Water Agency provides water and flood protection within California’s Tri-Valley region of eastern Alameda County. The agency hired Tierra Plan to create their StreamTracker surface water portal for viewing and managing data from their network of stream gauges and rainfall sensors.
We worked with the Monterey Peninsula Water Management District to design and build a modern system for data sharing and visualization. Our sustainable solution informs and engages the public through a simple interactive map and consolidated water data platform that’s future-proof and highly scalable. The tool brings current and historic surface water data to life through maps, graphics, and a dashboard for quick real-time overview of the watershed.
Tierra Plan’s See Upstream Water Data Portals are intuitive, responsive web applications that display water sensor data in interactive maps, charts, and dashboards to provide water agencies, hydrologists, planners, and the public with a central platform for monitoring surface water conditions, tracking groundwater conditions, and sending flood alerts.
We can integrate unlimited sensors and sources, bringing streamflow, stage, precipitation, reservoir, and temperature and other data together in one platform, including sensor data from USGS, Aquatic Informatics, Hydstra, Xylem’s Hydrosphere, LoggerNet, Mesonet, CIMIS, and other systems.
The API consolidates and standardizes all water sensor data into a single, consistent source that makes it easy to download, share, and integrate data with other applications.
Sensor configurations and locations are managed through a secure administrator portal. This management interface lets you add and remove sensors, customize dashboard layouts, and define your own streamflow thresholds.
Reach out and let’s talk about your project. After we know more, we can provide a proposal to address your needs. Once a project’s underway, we provide hands-on guidance to organize and optimize your portal’s design, content, and data, ensuring your portal is practical, intuitive, and informative. We can host your water portal or help with deployment for hassle-free deployment. We also provide technical support, features updates, and bug fixes.
