Dear Colleagues:

I am seeking a report generated for EPA by Battelle, Columbus, Ohio, in 
the 1980s.  The citation is:

Sabourin, T. D., R. S. Hayward, B. Cornaby, and R. L. Faulk. 1986. 
Biological consequences of lake recovery. Technical Report to U.S.E.P.A. 
from Battelle Columbus Division, Columbus, Ohio.

None of the authors has a copy; Battelle and EPA searches have come up 
dry.

Dr. Sabourin (co-author) reports (pers. comm.) that this work resulted in 
the following 1986 SETAC presentation:

174
WATER QUALITY IMPROVEMENT AND NUISANCE AQUATIC
LIFE. T. D. Sabourin, B. W. Cornaby, R.
T. Faulk and R. S. Hayward, Battelle Columbus
Division, Columbus, OR, U.S.A.
 
Improved water quality over the last decade
has resulted in mostly positive but some
unexpected negative changes.  We have found
many cases where improved water quality is 
accompanied by changes in plant and animal
species assemblages that give rise to nuisance
biota or other undesirable biological conse-
quences.  Five examples follow:
o expansion of rooted macrophytes - due
   to reduced turbidity
o development of toxic algal blooms - follow-
   ing cleanup of a river’s Zn load
o revitalization of sea lamprey populations
   attributed to tributary cleanup
o invasion by exotic species - shifts in
   lake trophic status opens niches
o return of mayfly swarms - due to reduced
   inputs of limiting nutrients.
We will report on additional scenarios of
biological nuisances.  We advanced causal
and correlative associations by 1) recovery
technique (e.g., aeration, dredging) and
2) nature of environmental change induced
(e.g., turbidity, temperature) to develop
a preliminary conceptual model.  The model
can aid future management plans where recovery
manipulations are contemplated.  This paper
will prepare you to more readily accept nui-
sances associated with cleanup activities.
 

Dr. Hayward passed away awhile ago, and I’m seeking a copy of this 
Battelle/EPA report for a retrospective on his life that I’m writing.

Thank you in advance for your consideration of this request.

Douglas Noltie.
