Range Water Level Difficulty Comment -999.00 -0.00 ft extremely Low-somewhat Low II(III) Too low (below 100 cfs). 0.00 -0.50 ft somewhat Low-barely Low II(III) Possibly 100-150 cfs. Very low (though possibly boatable). (Unlikely to adequately flush ice in winter.) 0.50 -1.00 ft barely runnable-med runnable II(III) Possibly 150-220 cfs. Possibly low to low-moderate level. Check for ice shelves and ice floes. 1.00 -1.50 ft med runnable-a bit pushy runnable II(III) Possibly 220-300 cfs. Possibly low-moderate to moderate level. Check for ice shelves and ice floes. 1.50 -2.00 ft med runnable-a bit pushy runnable II(III) Possibly 300-400 cfs. Possibly moderate to high-moderate level. Check for ice shelves and ice floes. 2.00 -2.50 ft a bit pushy runnable-high runnable II(III) Possibly 400-500 cfs. Likely moderately-high to high flow. Check for ice shelves and ice floes. 2.50 -3.00 ft a bit pushy runnable-high runnable II(III) Possibly 500-600+ cfs. Likely extreme high flow. 3.00 -5.00 ft barely High-extremely High II(III) Extremely high level ... possibly too high? Check for ice shelves and ice floes.

usgs-04087088	225 - 625 cfs	II(III)	01h17m	25.4 cfs (too low)
	Too low. Boat and paddle abuse (scraping down a cement ditch and rocky rapids).
Gauge (18.1 sq.mi.) is on listed section, thus accurately reflects flow. Flow is extremely 'flashy' and WILL CHANGE SIGNIFICANTLY by the time you get there

Boat and paddle abuse (scraping down a cement ditch and rocky rapids). 225 - 325 cfs barely runnable-med runnable II(III) Low/scrapey, especially through 'remediation' downstream of Hwy.41/45.

DO NOT PUT ON IF FLOW IS STILL RISING! 1000 -5000 cfs somewhat High-extremely High II-IV Outrageous flows. DO NOT PUT ON! Flow will change while you set shuttle and while on river! Bridges downstream on MenTosa will not allow passage!
