2 USGS Streamgages · Colorado River system
Loutsenhizer Arroyo flows and levels
Loutsenhizer Arroyo is gauged at 2 USGS streamgages in Colorado, each tracked by Rivermatics. The mainstem runs about 15 miles (24 km) from headwaters to outlet. It drains into the Colorado River system. It drains roughly 73 square miles at its outlet. The gauged reach falls about 130 feet, from 5,380 feet down to 5,250. Rivermatics issues a daily machine-learned 14-day flow outlook at 1 of them.
Gauges on this river, upstream to downstream
Ordered by drainage area, which is how far down the river each gauge sits. April and July figures are long-term median daily flows for that month from the USGS record — historical normals, not a forecast and not today's reading.

Common questions
- How many gauges are on the Loutsenhizer Arroyo?
- Rivermatics tracks 2 USGS streamgages on the Loutsenhizer Arroyo, across Colorado. Each has its own page with the site's full flow record and monthly normals. The river may carry other gauges that publish neither daily values nor discharge statistics; those are not tracked here.
- Is there a flow forecast for the Loutsenhizer Arroyo?
- Yes, at 1 of the 2 gauges. Rivermatics trains a machine-learned model — a temporal-fusion transformer — on each basin's observed flows, weather and snowpack, and issues a daily outlook reaching 14 days ahead: a median estimate inside a confidence band, not a single number to bet on. Every forecast is scored against days the model never trained on, and that track record is published on each gauge's live screen.
- What river system is the Loutsenhizer Arroyo part of?
- The Loutsenhizer Arroyo drains into the Colorado River system — it is a tributary somewhere in that chain, following the flowpath down to its terminal river. Rivermatics builds this from the USGS/geoconnex reference-mainstem network rather than from names.
- Can I use Loutsenhizer Arroyo data for flood or safety decisions?
- No. Rivermatics provides estimates, not guarantees, and the readings and forecasts here may be delayed, inaccurate, or wrong. Do not use them for navigation or for any safety, rescue, or emergency decision. Check the National Weather Service and USGS directly, and use your own judgment.
