Biological Considerations for Water Transfer Planning
A comment to the SWSt7 August, 2004 .
John Wiener Oohn.wiener@colorado~edu; 303-492~6746; Campus Box 468, University of
Colorado, Boulder, CO 80309.0468), writing solely as an individual.

The reason for these comments (3 pages of notesj annotated references following):

It is not apparent to an outside observer than anyone is charged to take an overview of the range
of potential consequences of the coming large.scale water transfers. It is an historical outcome
that water policy based in market allocation and traditional water law has resulted, so far, in
"segmentation of analysisH.. That js, when a broad policy is implemented in small incrementst
analysis of any given increment may overrook cumulative and synergistic impacts resulting over
time and in summation.. The simple example is environmental impact analysis of only a mile of
road at a timet where there will be a network of many miles and many roads in total. Because
transfer has been by markets in private property, no planning or evaluation criteria have been
generally developed or accepted. Encountering critical thresholds of cumulative impact can be
expensive and responses can be sto.w (Platte River Recovery Program DEtS, Freeman 2003)~

Therefore, it is my intent to nput some issues on the table.', without intent to disparage the work
done and underway. Rather, I hope this will help the SWSI groups with their discussion, and
perhaps herp the Water ConseNation Board consider further staff and interagency investigations
of these issues. Andt I hope that public interests may be better identified and better served,
perhaps through opportunities for private contributions, and perhaps targeted support for
contributions such as conservation easements~ Private support for public benefits may be
surprising,. and should certainly not be sought only from the agricultural and rural people most
likely to be impacted by the coming water transfers; everyone, including the urban and suburban
population, benefits from extemalities now provided by water distribution. The Water
Conservation Board staff win surely take the lead in these issues, given its role and evolution of
expertise with in-stream flow issues, and it is hoped that this comment will support such work..

Since the social and economic issues involved with moving water from agricultural uses have
been raised. this comment is directed to support of a "biological alternativell, in which the
productivity of the environment is the thing to be maximized. Such an alternative would be
valuable to help avoid inadvertently or unknowingly reaching some criticaf threshold, and to know
how weJl this alternative matches other alternatives. These comments do not duplicate previous
comment on other subjects..

These comments are in three parts: (1) Two pages of very brief djscussion of themes that
emerged from a survey of scientific literatures; (2) the bibliography from the survey; and (3) a set
of annotations on the referencesf for interested readers, and a few additional remarks.
The following 'hemes. emerged from sUlVey of some of the literature. The annotations provide
explanation of sources.

Theme: The Big Picture is Missing

Too much has been changed already in the Eastern Plains of Colorado to presume we know
much now j or can easily foresee consequences of more dramatic change from changes in water
managementt agricultural policy~ or enmate variation. Extreme losses of wetlands, drastic
declines in plains fishes and birdst ross of native grasslands, and a great dear of research at
scales of better value to science than management leave us in a difficult position.. There are
continental scale estimates, and micro-scale research, but regionally, little in the way of a -big
picture" helpful for identifying thresholds, avoiding problems, or anticipating consequences.
Agriculture accounts for well over 85 percent of consumptive use of water; but there is almost
nothing on ditches and canals as part of the environment, or as partial substitute for converted
and drained riparian and wet lands of all sorts. This is especially problematic for Colorado since
there is regional research on the few remaining prairie potholes to the north, and the few
remaining playas and -depressional features to the south; in the middfe, there are rivers and
distributional features" beyond the foothills, and research on the natural but not much on the
