PRESQUE ISLE RIVER NEAR TULA, MI
usgs-04032000	500 - 1000 cfs	III-V	307d10h00m	145 cfs (too low)
	Likely too low for reasonable whitewater trip. (We need your input to help refine ranges here! Add a comment or report about recommended flows!)
Gauge (261 sq.mi.drainage) lies 10+miles upstream, so will understate flows (perhaps by 10-20%).
Range Water Level Difficulty Comment 0 - 250 cfs extremely Low-somewhat Low III-V Likely too low for reasonable whitewater trip. (We need your input to help refine ranges here! Add a comment or report about recommended flows!) 250 - 500 cfs somewhat Low-barely Low III-V Likely a bit grungy, possible ELF (Extreme Low Flow) run. (We need your input to help refine ranges here! Add a comment or report about recommended flows!) 500 - 700 cfs barely runnable-med runnable III-V Likely low-boatable flow. (We need your input to help refine ranges here!

PRESQUE ISLE RIVER NEAR CONNORVILLE, MI
usgs-04032150	6.20 - 6.60 ft	III-V	02h00m	6.34 ft (running)
	Likely low-to-moderate runnable flows. (Add a report to help define/refine these ranges.)
Gauge added summer of 2023. At present, no flow (CFS) correlations, only stage (FT.tenths).
Range Water Level Difficulty Comment 0.00 -5.80 ft extremely Low-somewhat Low III-V Almost certainly too low for whitewater run. (We need your input! Add a report to help define/refine these ranges.) 5.80 -6.20 ft somewhat Low-barely Low III-V Likely too low (maybe marginal?). (Add a report to help define/refine these ranges.) 6.20 -6.60 ft barely runnable-perfect runnable III-V Likely low-to-moderate runnable flows. (Add a report to help define/refine these ranges.)
BLACK RIVER NEAR BESSEMER, MI
usgs-04031000	2.80 - 6.90 ft	III-V	01h30m	~ 3.15 ft (running)
	Likely low-to-low-moderate flows. Help your fellow boaters! We need input to fine-tune boatable levels. Add a comment or report!
Reference gauge (Black River) should provide reasonable correlation for this river. Actual flows must be confirmed by on-site inspection.
