Colorado River Basin High Water

When they say the high water in the Colorado River basin this year will exceed that of 1983, it makes river runners pay attention. Guides who experienced Colorado River rafting in the mid- 1980's know big water. A number of factors come into play every time high water rolls through the canyons of Utah and Arizona, and it appears the same factors are at play this year. By February there was speculation, but so much still had to play out just right. The wet spring, and lower temperatures have kept the snowpack in the mountains late into the spring. Now we wait and see how fast it will all come down.

The Grand Canyon, with flows regulated by Glen Canyon Dam, will likely not see the high flows like in '83 because the Dam folks know what not to this time. But Mother Nature will do what she wants upstream of that dam. Cataract Canyon is the place for high water Colorado River rafting.

There's no better way to experience the power and magnificence of an untamed river than from the relative safety and security of a large J-Rig, patented by Western River Expeditions and named after its founder Jack Curry. Designed specifically for high water, rafting guides agree there is not anything quite like a J-Rig to flex over and punch through strong rapids.

High Snowpack- Always Good for Rafting?

The talk this season is of course the snowpack and water levels across the country. Global warming is obviously in full effect :) Most areas across the nation have experienced a good winter, which usually means that a good summer is to follow.

Good snow does not mean good river levels. Let me explain. We basically have two types of river-dependent factors to consider in the situation. Dam controlled rivers and natural flow rivers.

Earlier posts have talked about rivers across the nation changing over to dam controlled levels, in which certain river flows are guaranteed throughout the summer months. In general, good snow-pack and snow run-off are a good thing for dam controlled rivers. It means more water in the reservoir, and will continue to leave plenty of water flow throughout the coming years.

Natural flow rivers are a different story. Lets take a look at the Western U.S. as an example. The image here shows the current snow-pack levels across the various regions in the West. These numbers are a "percentage of normal", meaning that anything close to 100 is a very good thing, and anythin over 100 means higher-than-normal levels. Many locations that feed large rivers have over 100% snowpack for the season (still). But the weather still plays an important factor as to whether the snow will produce high, constant water levels or not.

Even with a good winter, if the weather heats up too fast, you run into flooding and fast run-off. So essentially, you would have a nice spring rafting season, followed by normal (or even below normal) water levels for the rest of the season. So it really still depends on mother nature and the transitional temperature from winter to spring to summer.

So remember that when the news reports a good winter, we still need to hold-on and see how the spring rolls out to accurately predict a good rafting season or not.

Mixed Reviews for Whitewater Rafting Levels

Looks like we are getting mixed reviews for the outlook of whitewater rafting around the country. Naturally, spring offers the best water runoff as the river catch the brunt of the early snow runoff. Colorado is experiencing great water levels (we all remember the horrible storms in Denver over the winter), perhaps the best they have seen in over a decade. You even have water agencies in Colorado and some parts of California letting out a little extra water now to prepare for the increased runoff. Other areas of California are lower than expected.

And for other parts? Southern Utah has average levels right now, but things are not looking so great for the rest of the season. Water levels on the Colorado River and Green River could see a 5 year low, bringing it back to the dry season three years ago.

The East coast is getting mixed results as well. North-East regions has levels as good as last year, some even running high. But travel down South towards the GA, TN region, and things are running in the 10% level of where they should be.

It will make for an interesting season across the country, and hopefully everyone will at least have an increase over last year.
