Watching Lake Levels

gates 550

May 10, 2017 ~ I've been wearing out two apps on my iPhone the last two weeks -- the weather app and the USACE Little Rock app.  After the rain stopped, it's been the corps app.  I'm watching lake levels, as we watch 23,000 c.f.s. of water move past our resort here on Taneycomo.

It's an amazing amount of water moving through the system, but what's more amazing is that Table Rock's level hardly budges after a day of 10 flood gates and three turbines of water is removed from the lake.  Beaver's level remains the same because that water is being held.  So will Table Rock's water as soon as the three lakes -- Beaver, Table Rock and Bull Shoals -- are balanced, according to the Corps.

On the USACE app, there's a section called Lake Forecast.  This gives either what a lake crested at and the date or the estimated crest level and the future date.  According to the app, Bull Shoals is to crest at 692.3 feet on May 14th.  When a lake or river crests, it usually means that's the level it stops rising and starts to fall.  If this is true, either the flow into Bull Shoals will slow or stop or water will start to be released from Bull Shoals when the lake reaches 692.3 feet.  My guess is that both will happen to some degree.

Another level and flow I've been watching is the USGS water monitoring station at Newport, Arkansas.  This information is given on the app labeled White River Basin.  The reason this level and flow is important is because this section of the White River, before it dumps into the Mississippi River, was flooded a week ago.  This is the reason the corps could not release water from Bull Shoals--it would add more water to what already was close to a record flow.  We were told by Steve Bays, of the corps' Little Rock office, that officials couldn't release water from Bull Shoals until seven days after the White River crested at Newport.

There is another section that has my interest, (and I'm not sure it has any bearing on our lakes,) but it's in the White River Forecast section.  It shows estimated flows and levels of the Mississippi River at Arkansas City, AR, which is below where the White and Arkansas rivers enter.  Today the forecast for crest is May 14th, four days from now.  Again, I'm not sure what bearing this has on the future release of Bull Shoals, but it is another piece of the puzzle that the corps uses to manage water in the system.

This morning, Bull Shoal's level is 691.01 feet.  It is rising .63 feet every 24 hours, but this rate of increase is slowing as the lake rises.  Still, it looks as if it will reach 692.3 feet on the 12th or 13th of May.  What then?  The answer and effects of that question will play out on Lake Taneycomo and the flow, or lack thereof.

It makes sense to me that two things will happen.  One, the flow from Beaver/Table Rock will have to be slowed or stopped until Bull Shoals starts releasing water.  Bays said that the three lakes would be balanced as to volume of water in each, keeping about the same amount of freeboard space in each lake.  The term freeboard is the amount of space available for water storage within the flood pool of a lake.  Two, Bull Shoals, at some point, will have to start releasing water.  How much, how fast?  Hard to say, but I would guess that officials will release as much as they can, taking into account flows on the Mississippi and Arkansas rivers.

The hope is that this water will be moved out of the White River system before more rain falls in the basin.  A little rainfall in spotted areas won't hurt, but heavy, widespread rainfall will cause more flooding, especially in the tailwaters. The lakes simply can't hold much more runoff.

Now, what that does for boating and fishing on Lake Taneycomo . . .

Fishing off the bank or from docks has been tough with this high flow of water.  Fish tend to seek out slower currents in which to float and pick off food as it flows by.  This could be along the bank, behind structures in the water or on the bottom where the current is slower.  Getting your bait or lure to these spots, even fishing from a boat, isn't the easiest thing to do without practice and a keen sense of where your bait is at any given time.

I've said in past reports and articles, that if you're not losing jigs and rigs on the bottom, you're probably not catching fish.  If you're not feeling the occasional tick of the bottom when drifting, your bait isn't being seen by trout on the bottom.  Two things to do --  add weight and/or add line.  No three things --  change where you throw the line.

If I'm having trouble getting down in fast, deep current, I won't throw directly upstream as usual.  I'll throw to the side or just a little downstream to the side and let the sinker take my bait to the bottom.  Then at some point I'll have to reel back in and repeat when the line moves upstream and stops bumping the bottom.

There is a fourth thing you can do, but it takes time to learn how to manuever.  It's using your trolling motor to slow the boat down, allowing the weight to drop down to the bottom with the slack line this creates.  But if you slow the boat down too much, your weight and bait will catch up to the boat and probably get hung on the bottom.  This technique is a little tricky.

Now if and when the water slows down, I think fishing is going to get really good!  The fish will have had a vacation from fishing pressure for almost two weeks and the absence of high, fast water will make getting to the fish much easier.  During this time, the Missouri Department of Conservation have been stocking rainbows as usual, so there will be lots of fish in the lake to catch.  With Memorial Weekend just around the corner, and the influx of fish normal stocked for the busy weekend, trout fishing should be excellent.
