How can I be notified that a lottery has opened?

There are three ways to know a lottery has opened.

What can I do on this website?

Use this website to submit lottery applications and permit applications for noncommercial Colorado River rafting permits.

Note: Anyone applying for a noncommercial Colorado River rafting trip (or listed as a Potential Alternate Trip Leader (PATL)) must have a river user account.

What are the general requirements for a noncommercial permit?

General requirements listed below, for more information see the Noncommercial River Trip Regulations (pdf file, 970kb).

What type of river experience is required?

There must be at least one qualified boat-operator present on the entire river trip. That person must have participated in a previous Grand Canyon river trip as a boat-operator in command of a boat or participated as a boat-operator in command of a boat on a river of similar difficulty to the Colorado River through Grand Canyon. Your boat-operator must be guided by a thorough understanding of the technical skill required to navigate the major rapids found in Grand Canyon National Park. The selection of boat-operators is the responsibility of the trip leader. Rivers of similar difficulty to the Colorado River through Grand Canyon (this list is not all-inclusive): Cataract Canyon, Utah; Lodore Canyon, Colorado; West Water Canyon, Utah; Middle Fork Salmon, Idaho; Rogue River, Oregon; Green River, Utah; Selway River, Idaho; Yampa River, Colorado; Tuolumne River, California; Main Salmon, Idaho.

Why is it called a "weighted lottery"? How does it work?

It's called a weighted lottery because we adjust (weight) each individual's odds of winning, so that those who have been on a recreational trip on the Colorado River less recently (or never) have a greater chance of winning a launch date than those who have been on a river trip more recently. The lottery system centers around the concept of standard points and, for those persons transitioning from the waitlist only, bonus points. The total points for a lottery application are calculated by adding the total standard points and total bonus points. The total standard points for a lottery application is the minimum (or lowest number) of all standard points held by the trip leader and any confirmed PATLs. The total bonus points for a lottery application is the sum of all bonus point held by the trip leader and any confirmed PATLs.

TOTAL APPLICATION POINTS = MINIMUM of all standard points + SUM of all bonus points

The next few paragraphs explain in more detail how points work to influence a lottery application's chances of winning.

Standard points are the basis for the system and are used to weight the lottery to give persons who have not been on the Colorado River recently a better chance of success than those who have been more recently. Calculating your standard points is easy: it's simply the number of years since you've been on a recreational river trip on the Colorado River between Lees Ferry and Diamond Creek (or won in a lottery, whichever is later), up to a maximum of five points. So if it's been five or more years since you've been on a trip, or you've never been, then you have five standard points, which means, essentially that you have five chances of winning (think of it as "five lottery tickets for your permit in the pot that we draw from"). On the other hand, if you were just down the river last year, you have one point. If it has been three years since you last went on a recreational river trip (noncommercial or commercial) through the canyon, you have three points. Keep in mind that this formula applies for both noncommercial (private) and commercial trips. So if you took a commercial trip last year, you'll have one standard point when you apply for a noncommercial trip this year.

Of course, there may be multiple persons listed on a lottery application, for example the trip leader and any confirmed Potential Alternate Trip Leaders (PATLs). So how do we calculate the total points for a lottery application as a whole? Simple: if no person listed on the lottery application has "bonus points" (see below), then the total points for a lottery application is the minimum of all standard points held by the trip leader and all confirmed PATLs. If the trip leader has five standard points, and there are two confirmed PATLs with three and four standard points respectively, the trip application will enter the lottery with three standard points, i.e., with three "tickets in the pot".

Bonus points (or extra chances) for persons transitioning from the old waitlist system. (Note: the following applies only to persons who were on the waitlist in 2006 and elected to transition to the lottery system with bonus points, everyone else has zero bonus points.) Persons transitioning from the old waitlist system were given one bonus point for every year they had been on the waitlist. These extra points remain viable indefinitely, and can be used year after year to boost the odds of success in the lottery. Once the holder of bonus points is awarded or goes on a recreational river trip (i.e., is a trip leader or confirmed PATL on a winning lottery application or a is passenger on a recreational river trip), their bonus points disappear and subsequent participation in lotteries is based on standard points only.

The total points for a lottery application with multiple applicants (i.e. trip leader and one or more confirmed PATLs) are calculated by combining the standard points and bonus points of all listed applicants. Bonus points are particularly powerful because they are cumulative across all applicants on a permit and act in addition to standard points. To illustrate this, consider the following scenario: Mike submits a lottery application with John and Betty as confirmed PATLs.

The number of points for this lottery application is calculated as follows: First, take the minimum of all applicants' standard points, then add to that number any bonus points the applicants have due to being on the waitlist. So, in the above case, take the minimum of standard points of all applicants: minimum(3,5,5)=3. Then add all the bonus points held by all applicants: 10 (from Betty). The total points for this application as a whole would be 13, i.e, this application will essentially have 13 "tickets in the pot" for the lottery.

What would cause me to lose my lottery chances (points)?

There are two ways for you to lose your lottery chances (points). First, your points will be reset to one if you are listed on a lottery application that wins (i.e. if you are on an application as either the trip leader or a confirmed PATL), even if your trip is later cancelled. Second, your points will be reset to one if you participate on a noncommercial trip or are a recreational passenger on a commercial river trip through any portion of the Lees Ferry to Diamond Creek section of the Colorado River through Grand Canyon National Park.

What are Potential Alternate Trip Leaders (PATLs) and why should I list them on my lottery application?

A PATL is a person who would be capable and willing to take over river trip responsibilities if the trip leader is unable to go. PATLs commit their points (standard and bonus) to the lottery application they are confirmed on. The National Park Service strongly recommends that all lottery applications have at least one confirmed PATL. If the original trip leader becomes unable to go on the river trip, and there are no confirmed PATLs, the trip will be cancelled. PATLs can be added to a river trip by the trip leader only when submitting a lottery application; see Noncommercial River Trip Regulations for clarification.

How do Potential Alternate Trip Leader (PATL) tokens work?

When you first log into your river user account after a lottery has opened, you will have two options available: "TRIP LEADER: CREATE NEW Lottery Application" and "PATL: JOIN AN EXISTING Lottery Application". Select "PATL: JOIN AN EXISTING Lottery Application" and you will be directed to a page with a PATL token. The token is unique to you, is for one specific lottery only, can only be used once, and is only good while the lottery is open. Give this token to the trip leader whose lottery application you want to join as a PATL. If the trip leader accepts you as a PATL, you will be automatically confirmed as a PATL on their lottery application.

IMPORTANT: If you provide a PATL token to a trip leader your are consenting to be listed (and your points used) on their lottery application. When a lottery application wins and a launch date is awarded, the trip leader and all confirmed PATLs have their points reset to one standard point --- whether or not they actually go on the river trip.

You can be listed on only ONE lottery application within a lottery. You can be either a trip leader or a PATL. Once you have been listed on one lottery application, you cannot be on any other application within that same lottery.

Why do you need to know the date of my last recreational river trip down the Colorado?

In order to give everyone a fair chance to experience a raft trip down the Colorado River, individuals are limited to one recreational river trip (commercial or noncommercial) on the Colorado River between Lees Ferry and Diamond Creek per year. Moreover, we weight the odds of winning the lottery, giving more chances to those who have not been down the river recently. Note that we do check the accuracy of last river trip date for all applicants listed on a river permit application before issuing the permit; false statements of last river trip date will result in cancellation of the permit and payments made to the National Park Service for that launch date will be forfeited.

How often do I pay the lottery application cost?

The lottery application cost is charged once for each LAUNCH YEAR for which a trip leader applies. After you have paid the lottery application cost for a LAUNCH YEAR, you can apply in all later lotteries for that LAUNCH YEAR for no additional charge. The application cost is paid by the trip leader after submitting a lottery application. IMPORTANT: Lottery applications with unpaid LAUNCH YEAR lottery application costs are not included when a lottery is run.

For example, you decide to apply in a lottery with launch dates in 2024, you submit a lottery application and pay, you are now eligible to apply in all later lotteries with launch dates in 2024 for no additional charge. If you then decide to apply in a lottery with launch dates in 2025, you would submit a lottery application and pay, you are now eligible to apply in all later lotteries with launch dates in 2025 for no additional charge.

How much are noncommercial river permit costs?

IMPORTANT: Lottery and river permit payments are nonrefundable.

Noncommercial river permit costs are:

River trip participants with an Interagency Pass do not need to pay the park entrance fee. Each pass automatically covers four boaters (the pass owner and three additional adult participants (age 16 and over)). For a list of valid passes, visit (opens in new window).
