Watershed & Water Resources Portal
Every water-supply figure in a plan or a permit is either measured or modelled, and almost no portal says which one you are reading. This app puts a watershed’s three published records on one navigation — what has been promised to diverters, what is actually gauged, and what has been assessed for quality. Descend the hierarchy and the records drop out: a grain notice names which book has just become an estimate. It counts claims and never claims volumes. Runs on live, verified California data.
Runs on Strata, or on your existing Esri services. Opens in a new tab.
How the app works — the walkthrough
A short, self-contained deck that walks through what the app does. Use the arrow keys inside it, or open it full-screen.It opens full-screen in a new tab.
Cloned a recipe, opened it in Claude — the app built itself
This app — and nineteen others — were generated in a single run from recipes handed to Claude. Clone the recipe from our GitHub repository, open it in Claude, and start building advanced, Esri-compatible web mapping applications immediately, on your own data.
Serve your data. Then talk to it.
Strata serves your spatial data over the ArcGIS REST protocol, then lets anyone explore it in plain language — on-prem and sovereign, at a fraction of Enterprise cost. Keep your Esri licenses.
