John Alden says:
"A fine surfing wave forms at the confluence of Big Rocky Run....and Cub Run as the level approaches 3 feet on the Route 29 gauge. It is a steep, fast wave with good eddy access on river left.
"For multiple runs you can eliminate the shuttle by taking out on river right at the powerline crossing and carrying back to the pedestal foot bridge and ferrying across to river left. A full run from Route 29 to the powerline crossing and the hike back to the put-in can be done in thirty minutes (without scouting)."
There is currently two pipe bridge crossings that are a must scout before you run. The first one is just down from the route 29 bridge and the other is at the foot crossing next to big rocky run. I found a link that describes what all of the construction is all about. Check out:
I am not sure if they are going to remove the pipe bridges but the construction is scheduled to be complete by the fall of 2011.
There's an actual gauge on Cub Run at Compton Rd -- you can get a reading at http://www.owml.vt.edu/owmlgis/index.asp (login as guest/guest) and click on station ST50. Those familiar with the run should be able to deduce a good level -- looks like it normally reads about 1 ft lower than the Broad Run gauge, although on 3/7/11 it crested at 12 ft(!) and 4400 CFS.
A thought on gauges. While the Broad Run gauge has been a decent correlation, I believe I found a better gauge while messing around on the USGS site: Its FLATLICK BRANCH ABOVE FROG BRANCH AT CHANTILLY, VA....which it so happens is a tributary that runs into Cub Run about a mile above the standard whitewater run (check the Site Map to verify)
Right now, with about 3/4" rain in the area, its showing about 60cfs and 1.6ft...not sure what the Cub Run bridge gauge is at, but I doubt its running yet. If people posted what their runs on the bridge were and what this gauge was at, I bet we could get a reliable correlation.
There is a temporary sewer pipe strung across Cub Run at the second footpath crossing, just above the confluence with Big Rocky Run. This will form a perfect deadly strainer at certain water levels. Imagine a round pipe with water flowing under it into a comb of concrete stepping stones.
Ran it today at 0' on the bridge gauge...wouldn't want to run it any lower than that, and it was a bit scrapey. The log at the bend is still there, though the bottom of the log was at river level...when I ran the creek back in June (around 2' on bridge gauge), I didn't notice the log, so I imagine it was underwater.
The gauge at Broad run read 250cfs, or 4.5ft, and was just peaking when we put on...so you can probably do it a bit below 5ft
cub run is a wild ride, i was thinking of runnin' it this past Tues...way too high!
This is a great creek to run but watch out for strainers and the log across it right before the first rapids as Jason said. Plan for next Monday again Jason. 7.2 feet this little creek is pure adrenaline.
6.5 feet is a good running level. There is one good size strainer tree stretched across the whole creek about 1/2 mile past the put-in at the route 29 bridge. It is right after a bend in the creek. At this level it was only about 1 1/2 feet above the water. Protage this spot and put in right after the log and it is smooth sailing the rest of the way. Also ran Big Rocky Run, there is one good size strainer, but it had enough room to duck under it, the main run on this was smooth. After the two creek meet move to the right, there is a large debre pile on the left that could propose a snag hazard. Great day for creeking!
13 feet is very high and creates a strainer condition--use caution above 9 feet. MIKE
Ran the lower wave train right before the bridge in October after about 3 days of solid rain. It was goin at about 8-9 feet. LOADS of fun, but even more strainers, so be careful. Thanks to Kenneth for the opportunity

The above gauge *seems* to provide an OK correlation for Cub Run. But use it with caution, as the gauge is on a different stream. Around 5 ft. appears to be a good minimum based several 2003 observations.
Locals often post levels on the Monocacy Canoe Club message board Paddle Prattle. A painted gauge is on the Route 29 bridge on the downstream side of the western abutment. Zero appears accurate with 1 to 3 feet making for a good run. At Yahoo (4 Ft.) the creek flushes through the trees.
