About Clarks Fork Yellowstone River Hydrology & Flow Dynamics
The Clarks Fork Yellowstone River monitoring station (USGS Gauge #06208000) is positioned at latitude 45.392° and longitude -108.895° near Clarks Fork Yellowstone River At Fromberg Mount, serving as a vital streamflow telemetry reference for recreational paddlers, tubers, anglers, and water resource managers in Montana at an elevation of 3520 ft above sea level.
Streamflow discharge on Clarks Fork Yellowstone River fluctuates based on seasonal precipitation, upstream reservoir releases, groundwater spring baseflows, and watershed snowpack runoff. Typical baseline discharge averages around ~804 CFS with typical river depths near 2.2 ft. Instantaneous discharge is measured in Cubic Feet per Second (CFS)—where 1 CFS equates to approximately 7.48 gallons (28.3 liters) of water rushing past the sensor each second.
Riverable continuously ingests 15-minute telemetry from the USGS National Water Information System (NWIS) and compares instantaneous volume against calibrated floatability ratings and safety thresholds.
Clarks Fork Yellowstone River Flow Sweet Spots by Activity
Different paddlecraft require different water volumes to float comfortably without scraping gravel bars or facing hazardous hydraulics.
Leisure Tubing
Gentle current with sufficient depth over riffles. Below 150 CFS expect frequent bottom scraping; above 600 CFS currents create entrapment risks.
Rec Kayak & Canoe
Optimal paddling flow with responsive tracking and easy maneuvering around gravel shoals, rock gardens, and gentle river bends.
Whitewater & Raft
Swift continuous currents, wave trains, and surging hydraulic features. Requires spray skirts, helmets, and intermediate-to-advanced river maneuvering skills.
Fly Fishing & Wading
Safe wading velocities and accessible bank pockets. High flows over 800 CFS make cross-river wading unsafe and cloud water clarity.
Essential Paddling & Tubing Checklist for Clarks Fork Yellowstone River
🦺 1. Wear a USCG-Approved PFD
Submerged strainers, unexpected drop-offs, and swift underwater hydraulics can overpower strong swimmers. Always wear a properly fitted life jacket.
🌡️ 2. Cold Water Shock Awareness
Water temperatures below 60°F (15.5°C) can trigger involuntary gasp reflexes and rapid muscle incapacitation. Check live water temp before launching.
🪵 3. Watch for Strainers & Log Jams
Fallen trees and branches allow water to pass through while trapping watercraft against obstacles. Give outer river bends wide berth.
☀️ 4. Hydration & Sun Protection
Water surface reflection intensifies UV radiation exposure. Carry at least 1 liter of potable drinking water per person for every 2 hours on the river.
Frequently Asked Questions About Clarks Fork Yellowstone River
How fast does water flow on Clarks Fork Yellowstone River?
River speed depends on discharge (CFS) and gradient. In general, typical floating speeds range from 1.5 to 2.5 mph in inner tubes and 3 to 4.5 mph in recreational kayaks.
How often is the flow data refreshed for Station #06208000?
The USGS satellite telemetry system polls sensor probes and transmits instantaneous discharge and gage height readings every 15 minutes.
Can rain in the watershed cause Clarks Fork Yellowstone River to flood?
Yes. Heavy rain events within the upstream drainage basin can cause rapid streamflow surges hours after a storm. Always check our 7-Day Rainfall Forecast tab before heading out.
