What class rapids are on the Lochsa River?

Sometimes referred to as the “Gauley of the West”, the Lochsa (pronounced Lock-Saw) offers one of the most famous whitewater day trips in Idaho. It competes with some of the world's most iconic rafting rivers, such as Cherry Creek in the Sierra Nevada mountains and New Zealand’s mighty Kaituna River. 

Many adventurers opt to tackle a 12-mile stretch of the Lochsa, known as the Goat Range or the Black Canyon, which encompasses the river’s densest whitewater section. This area is packed with continuous Class III and IV rapids that guarantee a thrilling ride. The journey begins with a rapid known as “House”, famed for its residential-sized waves and a large black rock resembling a house. It continues through “Split Creek”, home to two holes known as the “Toilet Bowl” and “Car Crash”. 

Aside from rafting this legendary 12-mile stretch, you can opt for our 20-mile full-day adventure that includes the technically challenging Class IV “10 Pin Alley” rapid. Additionally, you can join our “SUPER” Lochsa trip, which adds an extra 10 miles of rapids, including some of the Lochsa’s most challenging, such as “Triple Hole”, “Eagle Mountain”, and “Lost Creek”.

If one day isn't enough, consider joining ROW’s 2 or 3-day multi-day camping and whitewater adventure - our most comprehensive trip on the mighty Lochsa!

Finding the right flow

People frequently inquire about the ideal flow for rafting the Lochsa. While many rafters prefer high water conditions, the truth is that the river offers fantastic rapids at every water level. 

In May and early June, the river is elevated, swift, and chilly, providing an adrenaline-fueled adventure. During this time, flows generally range from 12,000 to 25,000 CFS (Cubic Feet Per Second), with each level presenting a unique yet equally thrilling experience. This period is best for fit and active individuals who are prepared to paddle continuously throughout the day. Generally speaking, you can expect unpredictable waves that create exhilarating rapids, with little opportunity to take a break.

As we move into mid-June, water levels usually decrease, and flows drop to between 3,000 and 12,000 CFS. During this period, we utilize smaller rafts, which heightens the excitement on the water. While the river is steeper and more defined, there is also more space between the rapids, creating opportunities to rest in the ever-increasing sunshine!

No matter the flow, the Lochsa boasts nearly endless Class III and IV rapids - the whitewater thrills are guaranteed! If you're not familiar with rapid classifications, you can learn more here. While the rapid classification system is clearly outlined, you may find differing opinions, largely influenced by the skill level of boaters, their familiarity with the river, and how they perceive consequences.
