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.

Rafting Article in USA Today

USA Today ran a good article about white water rafting and the snow levels across the country. Laura Bly did a great job at talking to the right people and getting the facts on what is really happening across the nation.

The article was along the same tune as my last post, talking about how winter snow and water has various affects on outfitters across the nation. Overall, you find mixed reviews. Why? Not just the reasons I pointed out in my winter snowpack post, but also because many rivers now are dam controlled.

So even drought conditions and water concerns has no immediate impact on some rafting regions (Southeast, Northeast, limited west coast). The problem is getting the conception that river rafting is directly correlated with water levels.

But overall, the rivers and reservoirs across the nation are looking good for the season. It will be interesting to see if gas prices have a negative affect on the season. So far I have gotten mixed reviews, some good, some o.k., some dont know. YTBD!

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.
