Platte River flows and levels

Platte River is gauged at 2 USGS streamgages in Missouri, each tracked by Rivermatics. The mainstem runs about 197 miles (318 km) from headwaters to outlet. It drains into the Mississippi River system. Drainage area at the gauges ranges from 1,760 square miles at Platte River near Agency, MO up to 2,380 at Platte River at Sharps Station, MO. Rivermatics issues a daily machine-learned 14-day flow outlook for every one 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.

Typical flow by month at Platte River at Sharps Station, MO

The furthest-downstream gauge on this river, so the fullest flow it carries here. Long-term daily discharge percentiles from the USGS record (up to 48 years of data), averaged within each month. These describe the historical normal range — they are not a forecast and not today's reading.

Common questions

When does the Platte River run highest?
May, on the long-term record at Platte River at Sharps Station, MO — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 1,662.3 cfs that month, against 196.7 cfs in October, the lowest. Upstream gauges peak on their own schedule; the table on this page gives April and July for each.
How many gauges are on the Platte River?
Rivermatics tracks 2 USGS streamgages on the Platte River, across Missouri. 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 Platte River?
Yes, at 2 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 Platte River part of?
The Platte River drains into the Mississippi 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 Platte River 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.
