The USFWS claims to
have enough scientific data to not only justify, but make necessary
a change in the Missouri river hydrograph. This change is supposed
to aid the recovery effort of the pallid sturgeon, least tern, and
piping plover.
Common sense should tell anyone with a basic knowledge of the
situation, this is not true.
The pallid sturgeon: USFWS says the spring rise "may" cue
the spawning of the pallid, but there is convincing evidence
available that shows the pallid is already being cued, and that cue
is a water temperature of 65 degrees. There is also evidence that
the pallid does not spawn in the mainstem of the Missouri, but goes
up into the tributaries. This takes place in the month of
May.
Tarleton H. Bean, author of Fishes of Iowa, Report of the State
Fish Commission, 1892-93 states: "Nothing is recorded of its
habits, except it runs up into the small streams in May for the
purpose of spawning". Any attempt at changing the hydrograph
in May will affect water temperature, and defeat the natural
reproduction cycle.
The piping plover: Although piping plover never successfully used
the Missouri River for nesting prior to the building of the dams
because of the day to day fluctuations of the river, they have
readily adapted to the consistent flows afforded by the current
operation of Gavin's Point. The spring rise will be a disaster for
them, because of their need to nest just inches above the
waterline, coupled with their arrival in late April and early May,
which means they will have laid their eggs just before the spring
rise.
The least tern will face the same plight.
Let's return to the pallid sturgeon. Presume for a moment that in
spite of the spring rise, they were successful in getting their
eggs laid and hatched. These larvae will eventually move into the
shallow waters of the mainstem. It is common knowledge that very
little shallow water exists between Gavin's Point and the mouth of
the Platte due to degradation. Let's assume sturgeon do manage to
find some shallow water. Just about the time they adjust to their
new environment, the summer drawdown occurs and in many cases
either leaves them high and dry or unable to find any more shallow
water. Either situation will lead to their demise.
This overview should convince any reasonable person that the spring
rise and summer draw down has problems, but there is more. The
USFWS says it is necessary to recreate the natural hydrograph, but
is it "natural?" Let me present an analogy to show the
answer to that question is a resounding "NO." We all know
what Mom's Beef Stew is and what constitutes the ingredients. We
need beef, vegetables, seasoning, and water. Does anybody really
believe a bowl of cold water could be placed in front of
"Mom" and she would agree it is beef stew? This is
exactly what USFWS is asking. They have a spring rise with, no
CARBON, no SEDIMENT, and no HUMUS, and they are trying to say it is
a "natural hydrograph." Mom wasn't fooled on plain cold
water being beef stew, and that other "Mom," Mother
Nature, won't be fooled with a hydrograph of sterile cold
water.
Does it take a degree in aquarian biology, or a Ph.D. in
ichthyology to reach this conclusion. You know the answer is no. It
only takes common sense.
There is more, 1,700 miles more, above Sioux City. The introduction
of non-native gamefish above Gavin's Point has wreaked havoc with
the vast majority of native species. According to the NAS report,
51 native species on the Missouri River are losing numbers, the
majority above Gavin's. There is convincing evidence, that
non-native game fish are eating them. The USFWS in answer to a
petition to list sicklefin and sturgeon chub on the Missouri River
as endangered replied: " predation has likely increased over
historic levels due to the stockings of piscivorous fish into the
reservoirs and remaining riverine sections. Future introductions of
non-native fish, and other organisms may threaten sturgeon chub and
sicklefin chub through predation." See Federal Register/Vol.
60, No.11 Wednesday, Jan. 11, 1995/proposed rules. One of the
results of this finding is the petition for endangered species
listing of the sicklefin chub and sturgeon chub were subsequently
withdrawn, and plans to get the blue sucker, and sauger listed were
canceled, even though warranted.
Every true biologist, or ichthyologist knows game fish are
eating native fish.
Barges aren't above Gavin's, and barges don't eat native fish, only
game fish do, and this is the biggest threat to native species in
any ecosystem. Yet American Rivers, has aligned itself with the
American Sportfishing Association.
Rebecca Wodders, American Rivers president, will be presented with
the woman of the year award by the American Sportfishing
Association in June. Where is the Sierra Club, the Audubon Society,
and the Nature Conservancy when the fish need them? Isn't there a
conflict of interest here, or is this just about money, not birds
and fish?
