Will there be enough water for our trip?
Rio Grande has a very slight gradient, making for good boating even when water volumes are low. River levels of 200 cubic feet per second (cfs) or greater are enough for canoes and smaller paddle craft. A river level of 400 cfs is generally the minimum for rafts. Refer to flow readings at NOAA, IBWC or the park's weather page for river level readings at various locations along the river. Note: The IBWC website will give readings in cubic meters per second, convert the cms number into cfs by multiplying the cms number by 35.3 Example: 14 cms X 35.3 =492 cfs.

Is the water polluted?
The Rio Grande and her tributaries reach far into the high country in both Mexico and the United States and all along the way livestock, industry, and human habitation leave their impact on the river. Section, flow, seasons, and countless upstream influences all affect the water quality.
What is the best boat for the Rio Grande?
Canoes work well here due to their durability, speed, and ease of mobility in shallow waters. Inflatable rafts are suitable for higher flows. There are numerous types of inflatable and rigid kayaks, these too can be a good choice for the Rio Grande. You should be familiar with your watercraft, know its limitations, and be prepared with repair kits, extra paddles/oars, and consider floatation for open canoes.
What about drinking water?
Replenish your drinking water at the Cottonwood Campground, Rio Grande Village, and certain springs along the Lower Canyons. Bring one gallon of water per person per day on your river trip. For the Lower Canyons; bring enough for several days, and re-supply in the Asa Jones area. Filter all water from natural sources.
