All standard gauges and common nicknames for whitewater runs in the United States are supported (as well as a few in British Columbia). Many abbreviations are also supported, such as: NF for North Fork, Snoq for Snoqualmie, etc. For example, the following requests all return the same river information:

• Level South Fork Stillaguamish
• Level SF Stillaguamish
• Level Robe Canyon
• Level Robe

This service is 100% volunteer created and maintained, but it costs a lot to keep it running. If you find this service useful, please consider donating what you can to keep it going!
