Meeting called to order 7:06 p.m.
1. PRESENTATION BY FRIENDS OF HERRING RIVER
Don Palladino opened by stating that decisions made for the Herring River Restoration
Project have been science based. There is an extensive monitoring system already in
place which will be used to prevent/minimize risk. The end result will be improved water
quality. He encouraged the audience to listen to the science and ask questions.
John Portnoy gave some background on the research that has been done on the Herring
River since 1980. John listed many areas of study, but focused on bathymetric water
quality. Points included:
He said that diking causes problems including invasive species, loss of habitat, storm
surge problem, degraded water quality, fish kills, high mosquito production and fecal
coliform contamination of shellfish beds.
Kirk Bosma is a coastal engineer with experience in hydrology. He presented the
physical aspects of the current conditions and what might happen with the HRRP.
HISTORY
He showed a map of the area pre-dike. It showed an opening at what is now Duck
Harbor. He showed a super imposed map that illustrated a 1000 acre salt marsh loss.
Originally the dike was built to drain the land to make way for development and to
reduce the mosquito population.
Kirk showed a table that illustrated that money from the Herring auction dropped off and
money spent on mosquito control increased after the dike was built.
HYDRODYNAMICS
Kirk shared a Bathymetric mesh showing the elevations in the Herring River (underwater
areas).
He then showed all of the places at which data was collected to see what the tides are
doing (velocity, salt level, depth, etc). The instruments in the field were used to compare
to the computer model and showed a very close correlation. The idea is that the model
can be very predictive as to what will happen when the river is opened.
He then showed a moving map of the salt water influx into the river. The opening is so
small that high salinity water is not getting very far up the river. The model showed what
will happen if the river mouth is opened (much more salinity).
Kirk then presented a velocity map and an interactive map of how the water will fill into
various areas.
SEDIMENT TRANSPORT
How much sediment will move and where will it go? 80 to 90% of the sediment is sand
and the rest is fine silt and gravel. He showed a grain size distribution model. Currently,
there is sediment movement seaward of the dike and slightly into Wellfleet Harbor.
Virtually none upstream of the dike.
If the river mouth was opened to 165 ft wide by 3 ft high (very large opening, not
proposed by HRRP for the beginning of the project) the model shows much more
sediment transport upstream of the dike.
Zack Dixon asked if there are sediment transport models further into the harbor. Kirk said
no, but they are considering it.
PROPOSED DIKE
7 slide gates, 2 combo side/flap gates and 16 concrete panels. Gates provide full control.
The beginning of the project will use slide and combo gates, but not full removal of
concrete panels.
ADAPTIVE MANAGEMENT
Kirk listed some of the things that are being measured and monitored so that they can be
checked against later and during the opening of the gates.
Joel Fox asked about the shellfish beds in the harbor and what might happen to them.
Kirk answered that John will address some of that later, but as far as sediment goes it will
go mostly upstream.
Question from the audience pointed out that the Woods Hole study acknowledges that
shellfish beds could be smothered. How will this be monitored and how will shell fish
industry be compensated? Kirk said that the statement was an expressed concern, but the
studies show that sediment will go upstream longterm. He said that he does have a
concern that the initial opening should be done very carefully.
Helen Miranda Wilson pointed out the black mayonnaise problem exists. She asked for
Kirk’s thoughts on if there is a possibility of the opening of the river helping with
sediment in the harbor. Kirk said that it is reasonable to think that it could help.
Barbara asked if dying vegetation will produce problems. Kirk answered that it is not his
area of expertise.
John Portnoy spoke about water quality.
Study by Nat. Seashore in 2005 asked What are the sources of bacteria? Septic? Road
runoff? No, because little land use change since 1965.
The Seashore concluded that the bacteria is likely to come from wildlife.
Fecal coliform survive well in low salinity, low ph and low dissolved oxygen. These are
the conditions in the Herring River.
Fecal Coliform is worst at low tide.
How do large rains affect fecal coliform? Concentrations shoot up, probably from runoff
from what was once the marsh plain. The source is from above the dike (also higher in
the Fall).
How will tidal restoration affect microbiological water quality? Fecal coliform will be
diluted by more salt water, dissolved oxygen and higher ph. This could lead to reopening
of shellfish beds near the dike.
John showed a California study that concluded that the greater the proportion of wetlands
in a watershed, the lower the bacterial loads.
Just the dilution factor alone will bring fecal coliform count to below the limit for
shellfish.
Mark Borrelli is a Coastal Geologist from the Center for Coastal Studies
How stable os the gut? There have been some changes since the dike was put in. It is
stable, but dynamic.
Could an inlet form? what is required for an inlet to form? a storm, a narrow, low-lying
barrier and waters of differing elevation. To maintain an inlet you must have continual
flow, a deep basin and enough movement to prevent shoaling.
Study shows that the lowest spot is not low-lying and is not narrow, there is not a big
difference in water elevation and it is not deep enough for continual flow.
Mark’s conclusion is that there is no way an inlet will form in the gut.
QUESTIONS
Will there be any use of herbicides? Don P. answered that request for permitting will not
include the use of herbicides and therefore no herbicides will be used.
Don reiterated that this is a science based project and that FHRR wants to answer any
questions.
Judith Stiles asked about the impact of the construction of the new dike? Steve Spear
(HRRC) answered was that there are standard regulations and practices that govern
sedimentation during construction. Don said that they will put together a report on what
to expect during construction.
Joel asked about what will happen to all the vegetation. Steve answered that the
vegetation management plan is ongoing. Some will be chipped, some will be burned and
some will be removed.
Barbara Austin asked about the permitting process? Phases? or is it a permit for the whole
thing at once.
Martha answered that there are two phases: 1) around the dike, and part of Mill Creek. 2)
Upper Pole Dike and the rest of Mill Creek only if an agreement can be reached with
abutters.
How long between now and the permitting is complete and work starts? Martha answered
2 years for permitting, then 2 to 3 years for construction, then 5-20 years for adaptive
management.
What about the Herring? John Duane answered that he sees only good things for the
herring. Steve Spear added that during construction there will be continuos passage of
water.
Dennis Cunningham asked when the raising of the roads will happen. Don answered that
it will happen during phase one.
Elspeth Hay asked what will happen to water flow at those roads? Don answered that
many culverts will be replaced and some enlarged.
Meeting adjourned 9:10 p.m.
