River Sanitation and Environmental Protection Requirements

Aquatic Invasive Species (AIS)

While not currently mandatory, the monument strongly encourages responsible cleaning and inspection of boats as a preventive measure to minimize the spread of AIS. AIS (such as zebra mussel, New Zealand mudsnail, or quagga mussel) can have devastating effects on the ecology of river ecosystems. Please clean and thoroughly dry your boat between river trips. Do your part to keep our rivers healthy.

Please keep a clean campsite. Cans and other refuse may not be discarded in the water or along the shore of the river in side canyons, trails, or any other portions of the canyon. All refuse material must be carried out. Directly strain liquid garbage and dishwater into the river through a rigid fine-mesh screen capable of holding small food particles. Place the solids in garbage bags that are stored in an animal-proof container. Use the acceptable disposal containers located at Split Mountain boat ramp or remove trash completely from the monument. Do not put garbage into the groover dump station. Please dispose of wet wipes, sanitary napkins, and personal hygiene products into the garbage. Do not dispose of these items in groover toilets.

Kitchen ground tarps must be placed under all food preparation and serving tables to leave the beach free of food scraps. The proper use of these tarps will minimize negative wildlife impacts and interactions at campsites. Put food particles collected on your kitchen ground tarp into the trash and not into the river or on the ground. Crushing food and beverage cans must be done on a tarp or below the high water line in a manner that will not leave food particles, liquids, or paper on the beach. The trip leader must ensure that participants properly dispose of refuse.

You are camping in bear country. All food, garbage, and equipment used to cook or store food must be kept sealed in a container that is contructed of solid, non-pliable materials. Proper food storage will also help keep smaller animals from causing issues at river campsites. Do not leave trash in your vehicle at the put-in or the take out, or in the vault toilets. This can habituate local wildlife, including chipmunks, squirrels, mice, skunks, and bears to human food.

Stop The Spread Of Multiple Trails

'Multiple trailing' and its consequent impact on vegetation and soils comprise a perennial problem at attraction sites and along backcountry trails. All river runners should stay on established trails and avoid short-cutting across fragile desert soils.

Campsite Impacts
Impacts above the sandy, post-dam riparian zone at camping areas continues to be a problem. Desert and old pre-dam riparian plant communities are particularly susceptible to damage and erosion due to trampling. River runners should set up camp in the more resistant, post-dam, sandbar areas. Please use already established tent sites.

Use Of Soap
Use of soap in side streams with Dinosaur National Monument is prohibited. The use of soap must occur in the main flow of the Green and Yampa rivers. You must stand in the main flow of the river to rinse off with a solar shower. The dishwashing setup and handwashing station, using biodegradeable soap, should be placed in the wet sand below the high water mark or in such a way as to leave the beach free of soap and food spillage.

Portable Toilets
All river runners must carry their solid human waste out of the river corridor. A waste carry-out system will accompany all multi-day trips on the river. The toilet system must provide for secure containment and an adequate volume of storage. The toilet system must be the washable, reusable type allowing for the sanitary transfer of waste materials to septic vaults or sewage treatment facilities. Plastic or metal waste containers must be sturdy enough to withstand strong impact, and they must have a leak proof lid (even when inverted). This system must be approved by Dinosaur National Monument. Your toilet system must be accessible during the day.

The use of bag systems (such as WagBags or PET) for transporting human waste is prohibited.


If you must urinate while hiking away from the river, go "HIGH and FAR" at least 100 feet from trails, backcountry campsites, and side streams, to avoid the buildup of urine. Due to the impact of high volumes of people visiting the same areas, when hiking away from your river camp, bag all human waste (feces) and bring it back to your river camp and deposit it in your reusable toilet.

Only feces, urine, and toilet paper should be put in the washable reusable container, not feminine hygiene products or baby wipes of any kind. The park uses a septic system and these items are not appropriate for a septic system.

The number of containers needed is dependent on the number of people and the length of the trip. It is easy to contain about 50 uses in a container measuring 2,000 cubic inches.

Many commercially available chemical additives and holding tank deodorants are available. The park strongly suggests the use of non-toxic, non-formaldehyde based additives to lessen the impacts to sewage treatment facilities. Formaldehyde is a known carcinogen.

Human Waste Disposal
A sewer dump station for river users only is located at the Split Mountain take-out ramp from early spring until the first freeze in the fall. Inquire at the River Office for specific dates.

Gathering Firewood
Gathering firewood of any kind is prohibited on the Green River above Echo Park year-round. Driftwood may be collected:
along the Yampa River,
and along the Green River below Echo Park.

Gathering other types of wood (dead, down or live) is prohibited at all times on both rivers.

Why are there limits on the collection of firewood?
Driftwood has become scarce in Lodore Canyon because 1) Flaming Gorge dam blocks wood from upstream source areas and 2) reduced spring peak runoff volume is insufficient to wash new woody material in to the river. High spring floods still occur on the free-flowing Yampa, where large driftwood piles can still be seen. Coarse woody debris (driftwood, trees, branches, etc.) provides an important food source for aquatic invertebrates, so food webs in the Green River have been altered and diminished by Flaming Gorge dam operations. Restrictions on driftwood gathering in Lodore help preserve this dwindling resource. Standing dead, down and live wood provide habitat for cavity-nesting species and insects, which are food for birds and other animals. These resources are protected in all national parks.
