Common questions

When does Lake Fork at Gateview, CO normally run highest?
June, on the long-term record. The median daily flow that month is about 882.1 cfs, against 44.1 cfs in February, the lowest month. These are historical normals for the date, not a forecast and not today's reading.
What is a normal flow for Lake Fork at Gateview, CO?
It depends on the month. In January, half of days historically fall near 46.8 cfs, with the middle 80% of days between 35.3 and 60.2 cfs. The month-by-month table on this page gives the full range.
How long has Lake Fork at Gateview, CO been measured?
Discharge records at USGS site 09124500 begin in 1937, about 89 years, covering roughly 9,200 days of published daily values. The long record is what makes the monthly percentiles on this page meaningful.
Is there a flow forecast for Lake Fork at Gateview, CO?
Yes. Rivermatics trains a machine-learned model — a temporal-fusion transformer — on this basin's observed flows, weather, and snowpack, and issues a daily flow outlook reaching 14 days ahead: a median estimate inside a confidence band, not a single number to bet on. A companion model forecasts each day's water-temperature high and low. Every forecast is scored against days the model never trained on, and that track record is published on the live gauge screen. Open live conditions to see the current outlook.
Where is Lake Fork at Gateview, CO?
The gauge sits at 38.29888, -107.23006, in Colorado, in hydrologic subbasin 14020002, at an elevation of about 7,836 feet, draining roughly 339 square miles.
Can I use Lake Fork at Gateview, CO 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.
