2011 River Levels
July 22, 2011 Update: The Deerlodge Park Campground has reopended. Restrooms and water are now available. The camping area may have soggy spots and mud. The flow of the Yampa River has decreased greatly over the past week, but still remains above normal levels for this time of year. The Green River has also decreased slightly.
Dinosaur's rivers—the Green and the Yampa—are expected to reach record or near record levels in the Spring of 2011 due to the heavy snowpack and wet spring. Some areas within the watershed received over 150% of the average annual snowfall. Actual flow rates for the rivers will be dependent on the how quickly the snowpack melts, which will be affected by temperatures and any additional precipitation.
The amount of water flowing through the rivers may have dramatic changes on the experience for visitors. Some river campsites, put ins and take outs could become inaccessible due to water levels or debris carried by the current. Some rapids may disappear completely underneath the water while others may become more challenging or require different routes than boaters have used before.

Special River Safety Considerations
Protect yourself - Always wear an approved lifejacket, protective footware and clothing. Because flood waters may carry additional bacteria or other biological hazards, promptly treat any cut or abrasion that has been exposed to the water.
River currents - In some areas the current will be much faster than normal. The location of the currents can change as well as the speed. Stay out of the water. Do not attempt to swim in the river under these conditions. Sharp drop-offs, sandbars and other unseen hazards make swimming dangerous.
Water temperature - The water in the rivers is extremely cold due to melting snow in the mountains. Shock from exposure to the temperature or hypothermia (loss of body heat) can set in quickly. If someone gets wet, get them into dry clothing and make sure they get warm as soon as possible.
Debris - The higher levels and swift current can carry debris such as logs, full-size trees and rocks. Always be on the lookout for obstructions caused by this debris. Additionally, since the rivers flow into the monument, they may carry in fuel tanks, animals, culverts, tires or other refuse. Do not disturb any unknown containers. Report any containers or other hazards that you find to park rangers to the River Office as soon as possible. Note the distance upstream or downstream from river miles listed on maps and guides. Include if the hazard was river right or left. Provide a brief description of the hazard and take a photo, if possible.
River edges - The force of the current can quickly erode the banks of the river. Be careful to stay away from the edges, particularily in places where the water has cut under the bank, creating an overhanging edge or what is also know as a "cut bank." These areas can collapse with no warning, causing anyone standing near to fall into the water and then swept downstream.
Power of the river - Do not underestimate the power of the river. Rangers watched full-grown cottonwood trees hit the hole at Warm Spring at 22,000 cubic feet per second in 2008 and saw the rapid's hydraulics thrust the trees several feet in the air.
Did You Know?
Do you know the difference between a petroglyph (pictured here) and a pictograph? Petroglyphs are images pecked into rock while pictographs are painted images. Dinosaur National Monument preserves both forms of Native American rock art.
