I'd be happy to write that page note, but I need to clarify: are you asking me to write this to a file (and if so, where?), or to display it here for you to review?

Also, to make sure the note is in the format you want:

  • Should it be markdown, plain text, or HTML?
  • Who's the primary audience (water managers, environmental monitors, general public, internal dashboard)?
  • Any specific tone (technical, accessible, urgent alert style)?

In the meantime, here's a draft note based on the data you provided:

---

Columbia River Discharge: Elevated for mid-summer

Current discharge at The Dalles stands at 163,000 ft³/s, running 18% above the 5-year median for this date. This reflects robust snowmelt carryover and above-normal basin precipitation year-to-date.

Recent trends: Flow has declined 4.7% week-over-week and 19.7% month-over-month as expected for summer recession, but remains 41.7% higher than this date last year—indicating a notably wetter basin compared to 2025.

Outlook: Continue tracking weekly decline as summer progresses and snowmelt diminishes. Compare to historical July averages to assess pace toward seasonal lows.

Let me know if you'd like me to adjust the framing or write it to a specific file.
