concentration because of the salts embedded in the shale. Any ground water
located below the mancos shale will not be affected because of the relatively
impervious nature of the deeper unweathered shale. The volume of shallow
ground water flowing above and through the weathered shale will be reduced as
irrigation systems and practices become more efficient.

E. Public Participation

Public participation in the Lower Gunnison Salinity Control Study
began when the Bureau of Reclamation issued an invitation for interested agencies,
groups and individuals to participate in formulating an interagency, inter-
disciplinary, Multi-Objective Planning (MOP) Team. The organizational meeting
was held in Montrose, Colorado, on May 4, 1977. The structure of the MOP team
and its subunits is shown in Figure IV-3. Soil Conservation Service personnel
have actively and continuously participated as members of the MOP team and in
some of its subunits. The subunits conduct evaluations ano analyses related
to each discipline and then meet together as a full MOP team to present results,
to resolve interdisciplinary problems and to set the direction for the overall
study.

The Bureau of Reclamation limited its study to the Uncompahgre Project, an
area roughly bounded by the Gunnison River on the north and the east, and
including the irrigated farmland west of the Uncompahgre River. The area
studied by the salinity control study includes the private farmland within the
Uncompahgre Project area plus private farmland and off-farm laterals in the
area north and east of the Gunnison River.
