📝 How to add new reports

To add a new archive entry, copy this template into the ARCHIVE array in the JavaScript section and fill in the fields:

{
  title: "Your Report Title",
  year: 2025,
  source: "Agency or Author",
  agency: "USGS",  // USGS, CDFW, USFWS, LCWPD, UC Davis, Tribal, Lake County
  summary: "2-3 sentence summary of the report.",
  takeaways: [
    "Key finding #1",
    "Key finding #2",
    "Key finding #3"
  ],
  tags: ["spawning","population","kelsey creek"],
  locations: ["kelsey","adobe"],  // creek IDs for map linking
  url: "https://link-to-report.pdf"
}

The locations field uses the same creek IDs from the interactive map (e.g. "kelsey", "adobe", "forbes", "burns", "manning"). This means a future integration can show related reports when someone clicks a creek on the map — just filter the archive by matching location IDs.
