EMAP-GRE Indicators Workshop Is a Success

                USEPA
The EMAP-GRE program held a Biologi-
cal Indicators Workshop in Duluth, MN
Oct. 24-26, 2006. The workshop was
sponsored by the Council of State Gov-
ernments and the USEPA. The workshop
was attended by over 70 people repre-
senting various state agencies, federal
agencies, and universities from the Upper
and Lower Mississippi River Basin. The
primary goal of the workshop was to de-
velop an analytical framework for data
that supports bioassessment of the Ohio,
Upper Mississippi, and Missouri Rivers.

The first day consisted of several presen-
tations covering selected topics related to
assessments. Dave Bolgrien,  EMAP-GRE
Technical Lead, presented an outline of
the EMAP-GRE assessment and an over-
view of the program. Karen Blocksom
(USEPA-NERL) presented a well re-
ceived talk on developing multimetric
indices of biotic condition. Ted Angradi
(co-Pi, EMAP-GRE) discussed progress
towards EMAP-GRE reference condi-
tions.

The next series of talks  covered indicator
approaches that were new to the EMAP-
GRE project. Predictive modeling (O\E)
and relative risk analysis was  presented
by John Van Sickle (USEPA-NHEERL).
Euan Reavie (U of MN-Duluth-NRRI)
discussed how periphyton and phyto-
plankton indicators may be developed for
Great Rivers. Paul Bukaveckas (VA Com-
monwealth Univ.) presented some pre-
liminary data forzooplankton, chlorophyll
a, and suspended particulates, and dis-
cussed how they can be developed for
indicators of Great River ecosystems.
Terri Jicha wrapped up the first day's
presentations with a talk on information
                                  management (IM).

                                  The following day a discussion of stressor
                                  variables was led by Terri Jicha (water
                                  quality), Deb Taylor (habitat and hydrol-
                                  ogy), Mary Moffett (landscape data), and
                                  Jim Lazorchak (fish and sediment con-
                                  taminants).

                                  Breakout sessions were organized by
                                  biotic assemblages (fish, invertebrates,
                                  algae) and stressor variables (water qual-
                                  ity, habitat/hydrology). Each group was
                                  asked to answer a set of questions per-
                                  taining to candidate metrics, autecology
                                  files, and the integration of stressor data.
                                  Throughout the 2 1/2 days report outs of
                                  each group's progress was discussed in
                                  one large group. On the last day each
                                  group was charged to create a roadmap
                                  showing how EMAP-GRE assessment
                                  documents and research products would
                                  be created.

                                  To foster more discussion, participants
                                  were given an opportunity  for a boat
                                  cruise on the St. Louis Harbor on Tues-
                                  day evening. Many folks braved what we
                                  here in Duluth affectionately call a nice
                                  cool evening on the top deck,  but still
                                  enjoyed the sights of one of the world's
                                  largest freshwater ports. Several people
                                  also took advantage of curling lessons at
                                  the Duluth Entertainment and  Convention
                                  Center in the evenings. From what I
                                  heard we should keep an eye out for Jeff
                                  Thomas at the next Winter Olympics.

                                  All presentations and attendee list can be
                                  found at the following website.
