Subject:  Invitation to bid on Aquatic Plant Community Assessment on
the Dennys River

NOAA  Fisheries is seeking bids to conduct an aquatic plant community
assessment on the Dennys River.  Please examine that attached RFP
which describes the scope of the project and required deliverables.
We request that bids be submitted to cover the full two years of the
assessment as detailed in the RFP, but that you delineate first year
and second year expenses separately.  If you are interested in
submitting a bid, please submit a proposal to Dan Kircheis, NOAA 
Fisheries by August 9, 2004.

Proposal due date:  August 9, 2004 (postmarked by)
Requirements:  2 year proposal with 1st and 2nd years clearly

Notice:  NOAA  Fisheries reserves the right to fund this contract on
a 1 year basis if it is deemed appropriate.  For more information
regarding the RFP, please contact Dan Kircheis:  [log in to unmask]

Assessment of aquatic plant communities in the Dennys River to monitor
and evaluate an experimental water quality mitigation project for
Atlantic salmon restoration

Work Plan

Following the listing of Atlantic salmon in eight coastal watersheds
within the Gulf of Maine, water chemistry was identified as a possible
significant limiting factor for juvenile life stages of Atlantic
salmon, particularly smolts and alevins.   Low pH, in conjunction with
low levels of calcium, and high levels of biologically available
aluminum in five Downeast rivers may be significantly impacting the
ability of Atlantic salmon smolts to effectively transition between
their natal freshwater environment and the salt water environment
where they spend their adult life.   Given the critical status of
Atlantic salmon stocks within the State of Maine, NOAA-Fisheries and
the Maine Atlantic Salmon Commission, in collaboration with other
government and non-government partners, plan to implement a pilot
liming project on the Dennys River to evaluate the effectiveness in
minimizing deleterious water chemistry affects on salmon survival.

Based on water chemistry parameters, stream flow, and biological
factors, current plans are to construct a fully computer-automated
liming doser at the Rt. 86 Bridge in Dennysville Station.  This doser
will apply a calcium carbonate solution during runoff events (i.e.
rain, snow melt, etc.) that often result in low pH, low calcium, and
high aluminum levels.  Historic information indicates that these
events most often occur between late October and late May of each
year; however, they may occur at other times of the year.

Project Scope:
Sampling of aquatic vegetation, including algae, shall be conducted in
each of the distinct habitat types (lentic and lotic) at and below
bank full elevation encountered in the segment of the Dennys River
targeted for lime treatment.  Additionally, sampling shall be
conducted at control sites representing similar habitat types above
the targeted treatment segment.   The sampling shall be conducted
during the growing season prior to the lime treatment and the growing
season immediately following the first lime treatment.  Sampling shall
be conducted in a manner that clearly documents any changes in aquatic
plant communities that may be associated with the lime treatment.

       Summary report of methods, location of sites (GPS coordinates),
species lists, descriptions of documented habitat types, and
comparisons of species composition and abundance among habitat types.
Report should also include findings, including documentation of rare
or unusual plant communities; conclusions; and recommendations.

       Electronic copy of data in a Microsoft office compatible format.
Preferably Microsoft Excel.

       Site photos, coordinates, and maps of the sites that are sampled
