White River Water Levels
Why is it best to look at Cubic Feet Per Second (CFS) flows rather
than "number of generators" online from the Bull Shoals Dam recorded
you call the Bull Shoals Dam recording (870-431-5311) to
see how many generators are running, you probably are aware that it
sometimes does not give a clear picture of the water levels in the White River.
There are a number of reasons for this; mainly:
#1 Generators are quite often run at less than full capacity.
#2 The 8 generators are not equal capacity. The 4
newer ones are bigger. The voice recording just reports that; for
example, 3 generators are online, but actually 2 could be running at 75%
capacity and 1 at 50% or anything else.
Understandably, the voice
recording that is updated all day everyday just is not going to get
into all this detail. This page is NOT a criticism of the voice recording. The recording IS
useful. For instance, any non-power releases by the Corp of
Engineers (usually in high water situations) will be on the recording.
This page and the chart/graph (opened by clicking on the "Month" link) is an ongoing effort to look at the actual Cubic Feet Per Second (CFS) that the dam is putting into the
White River. The idea is that ongoing data should show daily
patterns which are fairly reliable AT TIMES (until they change!).
Also, looking at the CFS provides a clearer picture of what happened before.
An example would be that you call the dam in the morning and it says zero
generators online, but you get to the river and find fairly high
water. Most likely, they were running a lot of water last
night. They attempt to report this on the recording but it is not
always very clear.
A prime example occurred March 5th when they went from zero generation
for several days. At 1:00, they started some generation. They
recording said 2 generators were now online. However, if you look
at the chart, it shows the CFS to be approximately 3300 CFS. This
is actually the equivalent of 1 (averaged/theoretical) generator running
at full capacity.
The data in my charts comes from this link.

(this explanation looks more complicated than it actually is)
Rather than calling the Recorded Tel # 870-431-5311
or looking at my charts (which are not updated very regularly), you can
use your smartphone or computer to access the same info that I use to
make my charts. Each report shows about 36 hours of past generation history.
The water will travel about 2-4 MPH. The more generators they turn on
the faster it will flow. At cotter, 18 miles below the Dam, we
figure 5-6 hours (very wide average) for it to get here. A
map showing the mileages from the Dam to points along the river is here
. The water will fall out slower than it arrives.

And it looks like this>>>>>>>>>>>>>>>>>
Other than the first two columns (date and time), the column you want is column #5 (Turbine Release - CFS).
1) Each generator at Bull Shoals is 3300 CFS (average) at full capacity.
2) Looking at the sample at the right, you can see that around midnight
on Feb 3rd they started some generation and by 1 AM Feb 4th they were at
1226 CFS. This is less than 1/2 of one generator.
3) I am writing this at 7:30 AM Feb 4th and just downloaded the file at
the right. I also just called the Dam Tel# (870-431-5311).
The Tel Recording says generation began about midnight and they are
running two generators. They probably ARE running 2 generators, but only at something like 25% of full capacity (each).
4) When will it get here? At 1AM on Feb 4th, they started some
small (1226 CFS) generation. I would expect to see a very small
water rise around 9-10 AM (using the lower 2MPH because they only turned
on less than 1/2 of one generator). 18 miles divided by 2MPH =
At Rim Shoals, about 24 miles below the Dam, I would expect the water will not rise until at least 12 hours from 1AM, etc. Important (especially if you are wading) >>> Unless they turn on more generators since you looked at this data.
If you are going fishing today, and just call the Tel#, you might expect
there is (or will be shortly) quite a bit of water (the 2 generators it reported) except
it might not be at Cotter quite yet (18 miles below the Dam).
You get to the river (Cotter) at 8AM with your boat and find it is pretty much
low. Which is fine for fishing, just not what you were expecting and you
may be restricted between shoals if you are not planning to shuttle and
don't want to get out and push back over the downstream shoal.
Or, much worse, if you want to wade, you might not go at
all because you think 2
generators might be too high.
Also, and very important, from the recording, you do not know what was happening before
By looking at this data, I can see it has been turned
off since 1:00 AM Feb 3rd. Therefore, at Cotter, 18 miles below
the Dam, I would expect it to be pretty much dead low (and it is)
plan to keep the charts as up-to-date as possible; probably try to update each
evening at a minimum. I just started this
March 1, 2012, so we will see how it goes.
I do not see this as replacing the recording as the recording will be
more current. The Corps of
Engineers has this same type of CFS info online here, but for a rolling 7 days.
Southwestern Power Administration has a telephone recording (866-494-1993) of projected generation that is sometimes very close. And it projects it "as the equivalent of" so many generators online.
This, in fact, would be a big improvement to the Corp of Engineers
current generation report at (870-431-5311). For instance, instead
of "4 generators online', if they could report it as "the equivalent of" 3 generators online and so on.
The message to take from the above information is; if you are calling
the Bull Shoals Dam number (870-431-5311) from Texas and waiting for
wade-able water or low water or high water don't believe everything you
The White River is eminently fish-able 365 days a year.
The Newport gauge
(stage/height) is a key "control" or determinant of what the Corp of
engineers can do relative to "non-power" releases from Bull Shoals Dam.
The following (in italics) is from the Corp of Engineer FAQ page.
What are the regulating stages in the current Water Control Plan?
The water control plan, simply stated, says releases from Beaver are
dependent upon the elevation in Table Rock and Bull Shoals Lakes;
releases from Table Rock are dependent upon the elevation in Bull Shoals
Lake; and releases from Bull Shoals and Norfork are dependent upon the
seasonal regulating stage at Newport, Arkansas. Release criteria for
the lakes was developed more specifically based upon the pool elevation,
pool elevation of downstream lakes, the time of year, and downstream
• From 1 December through 14 April - Regulate to 21 feet except, if a
natural rise exceeding 21 feet occurs, regulate to the lesser of the
observed crest or 24 feet.
• From 15 April through 7 May - Regulate to 14 feet except, regulate to
21 feet, from 15 April through 30 April, and 18 feet, from 1 May
through 14 May, if the four-lake system storage exceeds 50% full.
• From 8 May through 30 November - Regulate to 12 feet except, regulate
to 14 feet from 15 May through 30 November, if the 4-lake system storage
exceeds 70% full.
• Release a minimum of firm power and in extreme cases zero if a
significant reduction in critical downstream flood conditions is
• Prorate the flood control releases between Bull Shoals and Norfork to
maintain equal percentages of available flood control storage in NF and
• Release a maximum of 32,500 cfs from BS and 10,500 cfs from NF subject to a 50,000 cfs flow limit at Batesville.
• Curtail secondary power generation—releases exceeding firm power—until
six days after the crest at Newport. Secondary power releases should
provide that stages above the regulating stage continue to recede until
the regulating stage is reached.
