Runs and Levels
| Run | Class | Current Level | Reference Gage | Gage Quality & Information |
|---|---|---|---|---|
| Big Laurel Creek | III-IV- | 161 cfs (Ivy) 08/07/2020 19:30 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. |
| 50 cfs (estimated) 08/07/2020 19:15 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. | ||

| Russell Fork of the Levisa Fork of the Big Sandy, Gorge | IV-V | 846 cfs (estimated) 08/07/2020 19:30 EDT |
USGS: Russell Fork + USGS: Pound | Excellent. The gages that are combined to create this virtual gage are located approximately five (Pound) and seven (Russell Fork) miles upstream of the Garden Hole put-in. Alt: Army Corps of Engineers Russell Fork at Bartlick. This gage combines the Russell Fork and Pound River flows. It is located approximately three miles upstream of the Garden Hole put-in. Scheduled releases occur in October; unscheduled releases occur year round. Water takes approximately 2.5 hours to reach put-in. Annual calendar of scheduled Russell Fork releases. Color codes: minimum = 150, medium = 400 - 800, too high = 1500. |
| Russell Fork of the Levisa Fork of the Big Sandy, Upper | II-III (IV-) | 846 cfs (estimated) 08/07/2020 19:30 EDT |
USGS: Russell Fork + USGS: Pound | Excellent. The gages that are combined to create this virtual gage are located approximately two (Pound) and four (Russell Fork) miles upstream of the Bartlick Bridge put-in. Alt: Army Corps of Engineers Russell Fork at Bartlick. This gage combines the Russell Fork and Pound River flows. It is located at the Bartlick Bridge put-in. Scheduled releases occur in October; unscheduled releases occur year round. Water takes approximately one hour to reach put-in. Annual calendar of scheduled Russell Fork releases. Color codes: minimum = 400, medium = 800 - 1200, too high = 3000. |
| Saluda (Mosh Pit / Pop Up Hole) | (II) Park and Play | 2370 cfs 08/07/2020 20:15 EDT |
USGS: Saluda near Columbia | Excellent. Gage located a short distance upstream of the hole. Alt #1: Call 1-800-830-5253 for the daily release forecast. If SCE&G is releasing the hole will be playable; two turbines are good and all five can be ideal. 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. |
| Swannanoa | I-II | 168 cfs 08/07/2020 20:00 EDT |
USGS: Swannanoa | Speculative. Color coding inspired guesswork. Insufficient observations: Report your runs! Color codes: minimum = 100, medium = 150 - 300, too high = 400. |
| Toe River Gorge, Toecane to Red Hill Bridge | II-III | 1550 cfs (Nolichucky) 08/07/2020 19:30 EDT |
USGS: Nolichucky | Fair. Red Hill bridge visual gage: min = 0, opt = 1-2'. Generally runs when the Nolichucky runs; Noli gage 40 miles downstream. Insufficient observations: Report your runs! Color codes: minimum = 800, medium = 1500 - 2000, too high = 6000. |
| Toe River, South Fork, Carolina Hemlocks to Patience Mullindore Park | I-II | 302 cfs 08/07/2020 19:30 EDT |
USGS: South Toe | Fair. When over 700 cfs top half becomes Ocoee-like in nature. Watch for low water bridges that must be portaged. Insufficient observations: Report your runs! Color codes: minimum = 250, medium = 400 - 1000, too high = 1800. |

| Tuckaseegee, Devil's Dip | (II) Park and Play | 1440 cfs 08/07/2020 19:15 EDT |
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. Color codes: minimum = 700, medium = 2000 - 2800, too high = 3000. |
| Tuckaseegee, Dillsboro to Barker's Creek | II | 1230 cfs 08/07/2020 19:15 EDT |
USGS: Tuckasegee (Barker's Creek) | Excellent. Gage a quarter mile or so above the take-out. An annual calendar of scheduled releases is available at Duke Power's Tuckasegee Recreation Flow Calendar (select Nantahala Area on the dropdown menu; the link will be on the right side of the page you are taken to). The calendar is color coded: Releases on the East Fork of the Tuckasegee are colored purple, come from the Cedar Cliff PH, and are generally 500 cfs; releases on the West Fork of the Tuckasegee are colored red, come from the Thorpe PH, and are generally 250 cfs. 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. |
| Tuckaseegee, East Fork, Granny Burrel Falls to Rock Bridge (Upper Upper EF Tuckaseegee) | IV-V | 6.23 feet 08/07/2020 19:40 EDT |
AFWS: Rock Bridge SG | Fair. Thanks to Kirk Eddlemon for tracking this gage and working out the levels. Some of the color coding is still speculative, however, and it is always good to have more data: Report your runs! Note: AFWS gages can report sporadically. Here are links to the Rock Bridge hydrograph and Rock Bridge streamflow archive. Color codes: minimum = 2, medium = 2.3 - 3, too high = 4. |
| 0.04 inches (rain,12 hrs) 08/07/2020 20:25 EDT |
AFWS: Hogback RG | Speculative. Thanks to Kirk Eddlemon for tracking this gage and working out the levels. Except for the minimum the color coding is speculative, so Report your runs! Color codes: minimum = 1.5, medium = 2 - 2.25, too high = 3. | ||
| 0.12 inches (rain, 24 hrs) 08/07/2020 20:25 EDT |
AFWS: Hogback RG | Speculative. Thanks to Kirk Eddlemon for tracking this gage and working out the levels. Except for the minimum the color coding is speculative, so Report your runs! Color codes: minimum = 2, medium = 3 - 4, too high = 5. | ||
| Tuckaseegee, Ela to Bryson City | II | 1440 cfs 08/07/2020 19:15 EDT |
USGS: Tuckasegee | Excellent. Gage at TO. Alt: Call 866-332-5253 (toll free) or 828-369-4559 for release information. Color codes: minimum = 750, medium = 1250 - 3000, too high = 6000. |
| Tuckaseegee, West Fork | III-IV+ (V) | 263 cfs 08/07/2020 19:15 EDT |
BoatingBeta.com: West Fork Tuckaseegeee VG | Speculative. Calculated by subtracting the Thorpe and Cedar Cliff PH releases from the Tuck at Cullowhee flow. When flows appear high enough to boat, Duke Power is spilling water out of either/or Cedar Cliff and Glenville Lakes. Water spilled from Cedar Cliff can lead to a skunking; water spilled from Glenville for reasons other than recreation can lead to dangerous conditions. Duke Power posts information regarding spills from Cedar Cliff Lake on their Cedar Cliff Lake Message Page and from Lake Glenville on their Lake Glenville Message Page. They also post updated information on their recreational WF releases, including when those scheduled releases are cancelled, at the same link. An annual calendar of scheduled releases is available at Duke Power's West Fork Tuckasegee River Bypass Releases (select Nantahala Area on the dropdown menu; the link will be on the right side of the page you are taken to). Color codes: minimum = 250, medium = 300 - 350, too high = 400. |
| Tuckaseegee, Whittier to Ela | II (II+) | 1440 cfs 08/07/2020 19:15 EDT |
USGS: Tuckasegee | Fair. Gage well downstream of PI. Alt: Call 866-332-5253 (toll free) or 828-369-4559 for release information. Color codes: minimum = 750, medium = 1250 - 3000, too high = 6000. |
| Watauga Gorge | IV-V- | 270 cfs 08/07/2020 19:30 EDT |
USGS: Watauga | Very Good. Gage 2 miles upstream of PI. Color codes: minimum = 160, medium = 250 - 500, too high = 1200. |
| Wilson Creek, Gorge (flows) | IV | 1054.1 inches (estimated) 08/07/2020 20:10 EDT |
BoatingBeta.com: Wilson Creek at Adako Bridge VG | Re-estimation Needed. Based on flows measured at the Edgemont AFWS gage and 91 Adako Bridge visual observations reported between 11/19/09 and 3/13/2010. 86% of the predicted values were within +/- 1" of the actual values; 99% were within +/- 2". Because the Edgemont gage is located on Wilson Creek, this gage should be good year round. At high flows it takes approximately four hours for water to flow the 11.6 miles from the Edgemont gage to Adako bridge. The virtual gage takes this lag into account: the predicted flow at the bridge at any point in time is based on the flow at Edgemont four hours earlier. Note: The Edgemont gage appears to update only when the river level changes. To be safe, check the alternate gages when the timestamp is stale. Virtual gages require frequent re-estimation: Report your runs! Color codes: minimum = -6, medium = 0 - 6, too high = 12. |
| 91.06 feet 08/07/2020 20:10 EDT |
AFWS: Edgemont SG | Very Good. Located on Wilson Creek above the confluence with Gragg Prong/Lost Cove Creek -- eight miles upstream of the Gorge and 11.6 miles upstream of the Adako Bridge visual gage. At high flows it takes approximately four hours for water to flow from the Edgemont gage to the Adako bridge. The timestamp associated with this gage does not take this lag into account: what you see is the level at the Edgemont gage at the time reported in the timestamp. Note: The Edgemont gage appears to update only when the river level changes. To be safe, check the alternate gages when the timestamp is stale. Help maintain this gage: Report your runs! Note: AFWS gages can report sporadically. Here are links to the Edgemont (Wilson Creek) hydrograph and Edgemont streamflow archive. Color codes: minimum = 2, medium = 2.5 - 3, too high = 3.5. | ||
| 377 cfs 08/07/2020 20:15 EDT |
USGS: Johns River | Fair. It is best to look at sets of gages to determine if Wilson Creek is running. WC is a tributary to the Johns River; the Johns River USGS gage is located 7.5 miles downstream of the WC visual gage so flows on the Johns Creek gage are serveral hours behind flows on WC. If both the Watauga and Johns River gages indicate that WC is running it most likely is, and at a level close to that on the WC virtual gage. If, on the other hand, the Watauga is running at a healthy level and Johns River hasn't budged the rain may have fallen on the west side of the mountains and WC is dry. Color codes: minimum = 300, medium = 500 - 1600, too high = 2000. | ||
| 270 cfs 08/07/2020 19:30 EDT |
USGS: Watauga | Fair. When rainfall is widespread the Watauga is an amazingly good predictor of the level on Wilson Creek. Widespread rainfall occurs frequently in the Winter and Spring, less often in the Summer. Look at the WC rain gauges (is the rainfall widespread?) and the Johns River gage (is it rising?). If the answers to these questions are "no," go run the Watauga instead! Color codes: minimum = 170, medium = 280 - 370, too high = 600. | ||
| 41.9 cfs 08/07/2020 19:45 EDT |
USGS: Yadkin (Patterson) | Fair. The Yadkin is the next watershed north of Johns Creek. If rainfall is widespread and the Upper Yadkin is over 50 cfs WC is generally running; If, on the other hand, the Yadkin is indicating a good WC flow and Johns Creek is indicating a marginal flow there is a good chance the rain fell north of the WC watershed and WC is not running. Color codes: minimum = 50, medium = 150 - 250, too high = 350. |

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. |
