Upper Colorado River Alliance's network

5 peoplei5 people on this map.The large node is the subject of this page. Solid lines are what the register itself records (5). Form 990 filings give names without a person identifier; SEC insider filings carry a CIK.

The board

5 listediTime on the board is observed from the annual filings: the IRS files no appointment date, so the bar counts years from the first filing the person appears on - a lower bound, not a filed start date. Names are exactly as filed. The IRS publishes no person identifier, so this edition does not yet link a person across organisations.Time served and departures are observed across annual filings. Observed time served is a lower bound - a member may have joined before the first year on record.
