Don't know who designated the river levels, but 300 cfs (minimum run) is scrapy all the way down, whereas 800 cfs (flood state according to account) is what I consider a moderately low run. Here are my observations based on dozens of runs:

500-800= low (few play holes)
800-1200= medium (best novice/int. playboat run)
1200-2000=high (actually easier,as rapids and holes start washing out)
