Understanding Water Flow and River Levels
The Ozarks is a region that is known for its rugged terrain, dense forests, and winding rivers. The region's rivers are fed by a network of springs and creeks that flow into larger streams and rivers. The level of these rivers can fluctuate depending on a number of factors, including rainfall and dam releases. Whether you’re on the river in your own equipment or using a rental, understanding how to read the river levels is crucial for planning a safe and enjoyable outing on the water.
The first step in reading the river levels is to consult the United States Geological Survey (USGS) website. The USGS operates a network of gauges along rivers that measure the water level, flow rate, and other important data. By visiting the USGS website, you can view real-time data from these gauges and get a sense of the current conditions of the river you are planning to visit.
When reading river levels, paying attention to the water level and flow rate is important. The water level is measured in feet and represents the height of the water above a designated point, such as a gauge or a bridge. Water level, gage height, river stage, and river height are all terms used interchangeably when describing the height of a stream above the gage reference point.
Flow rate, on the other hand, is measured in cubic feet per second (CFS) and represents the volume of water passing through a given point in the river each second. A higher water level or flow rate generally means a faster current and a more challenging paddling experience. It’s important to note that different rivers have different optimal water conditions depending on your planned activity. For example, a higher water level or flow rate may be desirable for whitewater kayaking but may be dangerous for flatwater paddling or fishing.
The most common way of understanding water conditions in our region is by current and anticipated water levels. The National Weather Service uses gage height numbers to communicate to the public about different levels of flooding hazards. Flood stage is the gage height at which water begins to overflow from the natural river banks, thus causing damage. It is important to consider the overall conditions, such as weather forecasts and recent rainfall, when interpreting the data. Rainfall must be considered not only at the location you plan to paddle but also upstream locations. A paddler must consider the trend in the data presented. Noting whether the water level is rising, falling, or holding steady is important to have a comprehensive understanding of water conditions. A rising trend may indicate that the river is becoming more challenging or even dangerous, while a falling trend may indicate that the river is becoming more manageable
In addition to consulting the USGS website, talking to local outfitters like 37 North, fishing guides, and other experienced river users is a good idea. They can provide valuable insights into the current conditions of the river and offer tips for navigating the water safely and effectively. If you’re still feeling unsure about getting on the water, you can always book an experience with 37 North. You’ll enjoy the beauty of the Ozarks and local rivers, all the while not having to worry about your safety. 37 North lead guides have extensive knowledge of the rivers we operate on and have Wilderness First Aid and CPR certifications.
Staying informed about current and forecasted water levels, paddlers can take necessary precautions to ensure their safety. The availability of real-time river data and weather forecasts has made it easier for people to monitor river levels and make informed decisions. By being aware of the factors that affect water flow, we can both understand the power of water and enjoy the beauty and benefits that rivers bring to our communities.
