Subject:  National Stream Quality Accounting Network, Fiscal Year (FY) 2001

This memorandum contains a summary of National Stream Quality Accounting
Network (NASQAN) status and funding for FY 2001. Details of NASQAN station
operation and protocol changes are contained in the NASQAN National
Operations memo, which will be released at the National Meeting to be held
October 17-19 in Jackson, MS.

NASQAN Stations

The NASQAN station network (Table 1) has changed appreciably since last
year, reflecting the decision to shift resources from the Columbia and
Colorado basins to the Yukon basin for the next five years. NASQAN will
suspend operations at all stations in the Columbia and Colorado with the
exception of three index stations in these basins. In addition to the
routine water-quality monitoring in the lower Columbia River, a special
study will be conducted to investigate the use of continuous turbidity data
to refine the estimates for suspended sediment flux and delivery to the
Columbia Estuary.  NASQAN has also withdrawn support for three stations
that were previously operated in conjunction with the National Water
Quality Assessment (NAWQA) Program: Rio Grande at El Paso, TX; Yellowstone
River near Sidney, MT; Platte River at Louisville, NE. NAWQA will assume
full responsibility for operating these stations.

There are a few other changes in the network configuration in the
Mississippi and Rio Grande basins. In the Mississippi, the NASQAN site in
South Dakota will be moved from Pierre to Yankton, below all of the major
storage reservoirs in the Missouri. A new site will be started on the Ohio
River at Sewickley, PA, to characterize the upper Ohio basin because NAWQA
will not be operating the Allegheny-Monongahela study unit during Cycle 2.
In the Rio Grande, event samples have been eliminated. The funds saved from
this activity will be used for measurement of continuous conductivity at
three sites within the basin and for surveys of the two major reservoirs.
In addition, discharge at the terminal station (Rio Grande at Brownsville)
are much lower than was the case in the past both because of the drought
and because of more complete extraction of water for irrigation. This site
will be sampled only when there is substantial flow. The station
configuration in the lower valley will be re-evaluated during FY 2001.

Table 1 also contains the sampling frequency for all stations, including
the "fixed" samples whose collection costs are made in an initial transfer
at the beginning of the year and the "event" samples. Collection costs for
event samples are reserved until samples are collected to provide greater
flexibility to the program. These funds will be transferred in July, 2001.
Detailed sampling schedules will be released with the Operations memo at
the NASQAN meeting.

There will be greater variation among stations this year concerning which
constituents are measured. The final column of Table 1 indicates the number
of large volume samples to be collected for sediment chemistry analysis of
trace elements. In general, after a site has been adequately characterized,
no further sediment chemistry is collected, with the exception of a few key
locations in each basin.

Initial Funding Transfer

The amount of the initial transfer is shown, by District and by station, 
Table 2.  These figures reflect cost estimates provided by the Districts in
August, 2000. Although these amounts reflect the estimates in gross funds
as provided at that time, OWQ reserves the right to adjust the funding if
overhead rates change during the year.

The "Fixed QW Sampling" figures shown in the attached table should be
entered on the CBR request frame in AIS as your request for FY 2001
water-quality funding. Where applicable, funding for surface-water gages is
shown in a separate column and should be entered into the appropriate
request frame.

Analytical Schedules

Although there are no changes in the analytical schedules to be used this
year, the schedules have been changed to reflect changes in the analysis
for dissolved and particulate organic carbon. Different supplies will be
needed this year for these constituents. These issues will be discussed at
the NASQAN meeting in Jackson and in the FY 2001 NASQAN Operational Memo.
"Central" sediment labs will be used for all NASQAN samples to ensure data
comparability across the basins. All NASQAN samples from the Mississippi
and Rio Grande Basins should be sent to the Iowa Sediment Lab; Columbia,
Colorado and Yukon samples should be sent to CVO.

Laboratory Charges

Both National Water Quality Laboratory and Sediment Laboratory Charges are
directly billed to NASQAN using the appropriate basin account number.
Sediment lab charges are not included in the funds being transferred to the
Districts, although shipping costs have been included in the transfer.

Account numbers that should be used are:

Yukon River              4883-15010
Colorado River           4883-15020
Columbia River           4883-15030
Mississippi River        4883-15040
Rio Grande               4883-15050

These account numbers are to be used only for laboratory charges and not
for supplies, equipment or other costs. (Funds for those items have already
been included in the amounts transferred to the Districts.) Any charges to
these accounts directly by Districts will be rejected. Any extraordinary
expenses must be discussed with Rick Hooper. Once approved, funds will be
SV'd to Districts to cover such costs.

Program Coordination

Each NASQAN basin has a "Basin Coordinator" who is the primary contact for
operational questions. For FY 2001, the basin coordinators are:

Mississippi Basin: Richard Coupe (rhcoupe), Jackson, MS; (601) 933-2982
Rio Grande Basin: Dee Lurry (dllurry), Austin, TX; (512) 873-3071
Colorado Basin: Bob Hart (bhart), Flagstaff, AZ; (520) 556-7137
Columbia Basin: Valerie Kelly (vjkelly), Portland, OR; (503) 251-3244
Yukon Basin: Tim Brabets (tbrabets), Anchorage, AK;  (907) 786-7105

Rick Hooper (rphooper; Northborough, MA; (508/490-5065) serves as the
National Technical Coordinator, and is the primary contact regarding budget
