Track Bureau of Reclamation Hydromet & AgriMet station data with fast, scrollable hourly and daily charts. Pick your station, watch your parameters, set reference lines.
TerraMet puts U.S. Bureau of Reclamation (USBR) Hydromet and AgriMet station readings in your pocket, with clean, fast charts built for the field.
Browse a built-in catalog of more than 440 mapped stations across the Pacific Northwest region Oregon, Idaho, Washington, Montana, Wyoming, Nevada, and California. Not in the catalog? You can enter any station ID supported by the USBR to monitor it directly.
Pick any station by ID, by name, or by tapping it on the map, then watch exactly the parameters that station measures discharge, flow, water level, temperature, and more. Each station reports its own set of parameter codes (pcodes), and TerraMet shows just those.
FEATURES
• Interactive charts — Smooth, horizontally scrollable line charts with hourly and daily resolution. Scroll back through history; older data loads automatically.
• Multi-parameter view - Show or hide any parameter with a tap. Every line and its value axis share the same color, and the left/right scales stay pinned on screen as you scroll so you always know the values.
• Live updates - A built-in refresh timer tracks each station's data cadence and pulls the latest readings automatically, with a countdown to the next expected sample. A clear banner appears if the source data is lagging.
• Years of history - Jump between years, browse by month, and load any year on demand.
• Threshold reference lines — Draw a dashed reference line at any value for a station's parameters. Lines are saved per station and restored every time.
• Station map - Find stations on a map across the Pacific Northwest (442 stations in OR, ID, WA, MT, WY, NV, and CA). Blue pins have exact coordinates; orange pins are approximate. Any USBR station ID can also be entered manually.
• Parameter dictionary - Built-in reference of the standard Hydromet parameter codes and what they mean.
Your station selection and preferences are saved on device and restored the next time you open the app.
