Mon The Best Bet?
Biologist Confirms That Classic Will Be Tough
The pros complained about the fishery and the fishing during Bassmaster
Classic practice in Pittsburgh, Pa. Nothing new there. But how legit
are those complaints? According to a state fisheries biologist, they're
pretty much on the mark - but that doesn't mean he thinks this will be
a lame Classic.

Most fish caught at the Classic will be small, but these smallies were shocked up from the Allegheny River in June 2004.
We threw some questions at Dennis Tubbs, an aquatic resources
program specialist for the Pennsylvania Fish and Boat Commission, and
here's what he said.
BassFan: All the pros say the bass fishery is bad. Is that true?
Tubbs: A lot of fish are less than 12 inches. Our legal limit is
12, and a lot of times when they get over that, people take them.
(Classic competitors) will catch fish, but getting them over 12 inches
will be the issue.
How about the fishery as a whole?
We have a decent-size population – about 95 percent smallmouths
– but (not much) habitat. They're located in the rocks. Because of
flowing water, there's not a lot of vegetation.
Are there a lot of rocks or are the rivers silted in?
Anyplace you have moving water there are going to be rocks. At
the calm places above locks and dams it's silted in, but the biggest
bass populations are within a mile of the locks and dams. In surveys,
that's where the highest concentrations (of bass) are.
That's because of oxygen and temperature. These are larger,
slower rivers, so the dissolved oxygen levels are higher the closer you
get to locks and dams. That's the only turbulence on the rivers. Water
going over the dams raises the oxygen levels. That will be key in the
warmer waters we have right now.
But there are a lot of rocks, especially below some of the
locks – like in the wash, in the middle, where it's only a few feet
deep. The fish stay at the lower end, below the gravel piles below the
locks and dams.
The piles are below the no-boat buoys, so they're fishable.
Locals will go to the buoys and cast above them, but (Classic
competitors) can't do that.
What's the primary forage?
The primary forage is gizzard shad. I was looking at a school
(Thursday) that probably had 2,000 to 3,000 shad in it. They're about 2
inches right now.
If they find rockpiles, there will be crayfish and the jig
fishermen could do well. But crankbaits and spinnerbaits (will be the
primary baits) – something moving like a shad.
I you find a crawdad hole, that's a bonus. That's where you'll
find a big fish. I'm a jig fisherman myself, so I know some of the
spots. If you can find rocks below the locks – big chunk rock – more
than likely there's good population of crayfish there.
What will be the most important factor?
The big thing here is if someone can find cooler water. An
inflow, creek, stream, another river, a discharge – look at the
temperature difference, if it drops a couple of degrees. Right now the
water is so warm that a slight variation in temperature will hold the
Last weekend on the Ohio we had a (water) temperature of 85.
For Pennsylvania that's unbelievable. We're in a hot streak right now.
We've been having 90-degree weather and scattered thundershowers.
They're calling for a cold front to come through next week, which may
How about docks. Do they hold fish?
Docks and bridge piers hold fish, but creek channels, inflows,
discharge pipes – we have enclosed streams around the city (that dump)
cooler water. Anything with moving (and cooler) water will be key.
There were drought conditions in Pittsburgh. Is that still the case?
We haven't had a lot of rain, but it's not that bad. It's not a
drought. But the water is a lot clearer than what would be normal for
Pittsburgh. Topwaters seem to be working well this year, but normally
you don't have that clarity.
Visibility was 18 to 20 inches and now it's 30 to 40 inches,
which is odd for the rivers. Usually there's a lot of turbidity in the
But there's still barge traffic. Doesn't that stir up the water?
Barge traffic does stir it up, but it clears up fast. The big
thing is we don't have much water flow right now because of the lack of
Some people think that since they're fishing around rusty
pipes and industrial areas that the water quality is bad, which is
hurting the fishery. Is that the case?
You will find that 98 percent of the banks are pretty good, but
there are some hotspots. Those are old industrial sites that look
beautiful, but there's no life. Most of those are gone, but a few are
Overall the health of the rivers is really good. We just had a
mayfly hatch, and we've had several real significant hatches the last
couple of years. And again, you can walk down to the river's edge and
see large schools of shad.
How do the three different rivers fish? Is one better than the others?
This will be a thinking-man's tournament. The Monongahela has a
lot of fish. It has probably the highest density, but the fish will be
12 to 14 inches – they'll just be legal.
The Ohio has bigger fish. We've done studies where we've found
8-pound largemouths, but very few. There's just not the population
there. The Allegheny is in-between.
Then you have locks to contend with. You have to decide whether
to go to the Ohio for big fish and lose 20 to 30 minutes in a lock, or
be safe and go to the Monongahela, catch five legal fish and then
travel to find bigger fish.
Hopefully they'll have good gameplans coming into next week.
You could gamble and lose or come out way ahead. This is a unique
fishery because it has three distinct rivers.
Does that mean that each river can be affected differently by weather?
If we get a rain up north it does affect the Allegheny, and rain
in West Virginia does affect the Monongahela. So little storms in the
area don't affect the whole river system, but one river could be very
muddy and another very clear because of wherever the storms hit. That's
what makes it unique in Pittsburgh. All three rivers could have
different conditions at the same time.
In view of that, how does the fishing hold up day to day? Can the fishing in one river shut down for some reason?
Any river can shut down any day. Something could happen upriver.
A lot of storms down south could raise the water in the Monongahela,
but it won't affect the Allegheny. You have to look at the whole
regional weather patterns, not just Pittsburgh.
You could be on a spot that's hot one day and catch a limit,
then go there the next day and not catch a single fish. They do move a
lot in river systems. Now, you may find a cool spot that holds fish a
couple of days, but normally that doesn't happen.
We will have a true angler come out of this. You'll have to fish a lot of techniques and you'll have to move a lot.
The pros are predicting that just catching a limit of keepers every day might win it. What do you think?
If you can get a legal limit of 2-pound fish, that's what it
will take. And if you can get a kicker, you'll be in real good shape.
But the final weigh-in will be extremely close. The Top 10 could all be within a pound.
