Big Thompson River

47 water rights in Weld County, Colorado, with priority dates from November 18, 1865 to December 30, 2005.

Listed in priority order. When Big Thompson River runs short, the rights near the top of this list are filled first and the ones at the bottom are the first asked to stop. Rights on the same stream in a neighbouring county, or on connected groundwater, can sit in the same line; the state's water commissioner or district office has the full picture. Sources are matched by name within the county, so two different streams with the same name would share this page.
