Runs and Levels
| Run | Class | Current Level | Reference Gage | Gage Quality & Information |
|---|---|---|---|---|
| Big Cedar Creek (Route 727 to Clinch River) | II-III | 1780 cfs (Clinch) 05/29/2023 21:45 EDT  |
USGS: Clinch (Cleveland) | Fair. Gage well downstream of PI. Insufficient observations: Report your runs! Color codes: minimum = 1400, medium = 2000 - 3000, too high = 6000. |
| Big Laurel Creek | III-IV- | 286 cfs (Ivy) 05/29/2023 21:30 EDT  |
USGS: Ivy | Fair. Confirm boatability using PI visual gage before putting on: min = -1' opt = .5-2.5' max = 3.5'. Alt: Look for .75" of rain in 24 hours on the Little Laurel Creek gage. Insufficient information: Report your runs! Color codes: minimum = 150, medium = 300 - 600, too high = 1000. |
| 1240 cfs (estimated) 05/29/2023 21:00 EDT |
BoatingBeta.com: Big Laurel at US 25/70 Bridge VG | Speculative. Confirm boatability using PI visual gage before putting on: min = -1' opt = .5-2.5' max = 3.5'. This gage is a guestimate based on the difference between the French Broad at Marshall and the French Broad at Hot Springs. It is set to read 50 cfs when the flow at Marshall is greater than the flow at Hot Springs. This happens in the period after the flow from heavy rain in the French Broad headwaters has reached Marshall but not Hot Springs. Under these conditions this VG is meaningless. Color codes: minimum = 250, medium = 350 - 550, too high = 800. | ||

Alt #2: the USGS gages the Saluda below Lake Murray Dam; this flow reaches the Mosh Pit a little over two hours later. Note: the color coding is for the Mosh Pit, but this hole is part of a series of rapids with plenty of opportunities for paddling and play at levels as high as 20,000 cfs! Color codes: minimum = 1000, medium = 3300 - 4500, too high = 5000. |

USGS: Tuckasegee (Bryson City) | Excellent. Duke Energy provides 3 day generation schedules every morning. Water arrives about 13 hours after release. A release on either Fork provides water to Devil's Dip. Alt: Call 866-332-5253 (toll free) or 828-369-4559 for release information. When the water is too low Devil's Dip is sticky and shallow, with the potential to break paddles in the player's right side of the hole. From 700-2000 cfs it is a sticky hole, from 2,500-2,800 (the optimum) an excellent wave/hole, from 2,800-3,000 it is tricky to get to, and over 3,000 it is gone.

You will note that from late May to early September, the higher East Fork releases are frequently Wed, Thu and Sat, while the lower West Fork releases are frequently Tu, Fri, and Sun. Color codes: minimum = 250, medium = 500 - 750, too high = 1500. |

Flow Color Coding Key
| Color | Interpretation | Meaning |
|---|---|---|
Note: assigning flow codes is highly subjective -- one person's "way too high" is another's "yahoo!" I have attempted to assign the codes relative to the typical person likely to boat the run at normal levels. "Too high" in this context means "the typical person found on this run at the levels it is most often paddled would find this run at this level very challenging." In general, runs are harder at higher levels. Use your discretion regarding the suitability of the run to your skill level and experience after seeing the level in person. |
||
| Too High | Beyond the envelope for the typical person likely to boat this run. | |
| High | Frequently run this high, but a stretch for the typical person likely to boat this run. | |
| Medium | Very enjoyable for the typical person likely to boat this run. | |
| Low | Frequently run this low. Worth a look but probably not a long drive. | |
| Too Low | Seldom run lower by anyone who isn't desperate and/or lives by the put-in. | |
| Don't Know | What's your opinion of this level? Email The River Gages Project. | |
Gage Quality Key
| Rating | Meaning |
|---|---|
| Excellent | Gage located on the reach near the run. Significant number of observations. |
| Very good | Gage located on the reach but a significant number of tributaries upstream or downsteam from the run, or gage based on rainfall or located on a proxy reach. Significant number of observations and strong correlation. |
| Fair | Gage located on the reach near the run but very limited number of observations; gage located on the reach but a significant number of tributaries upstream or downsteam from the run, or gage based on rainfall or located on a proxy reach. Limited number of observations and/or modest correlation. |
| Poor | Gage is based on rainfall or located on a proxy reach. Significant number of observations but weak correlation. |
| Speculative | Gage is based on rainfall or located on a proxy reach. Very limited number of observations or very weak correlation. |
