Gauge Information

Name Range Difficulty Updated Level
SANGAMON RIVER AT RIVERTON, IL
usgs-05576500 200 - 4000 cfs III+ 01h51m 9600 cfs (too high)
Very high flow. Gauge (2618 sq.mi. drainage) is well upstream. Drainage at Petersburg is 3063 sq.mi., or 1.17 times that, so flows may be ~1/6th again as high.


River Description

This is the premier park and play spot for Central Illinois.

Depending upon river level, play ranges from small waves, to big waves and a big hole.

A huge eddy houses debris (anything from trees to garbage to the namesake fish) so stay on your toes.

Gauge Information

Gauge Description:

The USGS gauge is approximately 30 miles upstream. At times of rapid waterlevel change, there is approximately a 20 hour delay from the level at Riverton to this playspot in Petersburg.

The drainage area at Petersburg is 3,063 square miles, whereas the drainage at the gauge in Riverton is 2,618 square miles. Thus, one might expect (on average) the actual flow at this playspot to be 1.17 times (or 1 and 1/6th as much as) the flow on the cited gauge.

Gauge/flow analysis based on Riverton gauge 1908 to 2008
Minimum mean daily flow during stated period 3 cfs (1914.10)
90% of time flow exceeds 84 cfs
10% of time flow exceeds 3,490 cfs
Maximum mean daily flow during stated period 67,700 cfs (1943.05.19)
10/90 ratio ('flashy-ness')
(under 3 is fairly steady, over 10 is quite 'flashy')
41.5
Average days per year over recommended 'low' threshold ( 75 cfs)  223

Paddled the DCD yesterday at 2500. It was too high for any significant play opportunities. There
was one shallow play hole that only allowed flatspins on far river left and a pretty small surf
wave on far river right. The DCD hole was very much washed out and only remained as a completely
green (brown) wave. Perhaps if you had a long boat, surfboard, or body board you could surf it
well. But no luck in my playboat.

Definitely worth the drive for a beginner looking to get some surfing or hole playing experience
under his/her belt. The whole length of the sangamon river is pretty tame class I stuff except for
this nice little drop in petersburg. We drove 2 hours and weren't disapointed. More experienced
paddlers may be bored with it or feel it wasn't worth the trip, but if you live close and are
looking for a whitewater fix, this is the place!
