designed to answer questions raised by ongoing research and address
issues not covered by the core program. These studies would
generally be shorter term projects (1-3 years).

The Seven Year Plan would be executed in three phases with the
cooperating agencies assuming responsibility for conducting various
aspects of the research.

In Phase I (FY 1991) several key research efforts involving long
term core research programs were implemented and design and
logistical issues resolved. Critical Core Research Programs which
were initiated in Phase I included: Adult monitoring/telemetry,
Early Life History research, Secondary Channel studies, and
Habitat/Flow studies. These studies will be conducted for the
entire seven year research period, and used as a baseline index
against which relative population changes can be measured over the
seven year research period. Objectives of Phase I included:

-help refine capture techniques,

-define abundance and distribution of target species in the
San Juan River,

-locate target species aggregation areas and spawning and
nursery areas,

-characterize physical habitat,

-acquire tissue from target species for genetic analyses,

-review and compile available information of San Juan River
water quality and,

-identify critical water quality parameters.

Phase II (FY 1992-1994) will involve implementation of some
additional core research and continuation of existing Core Research
Programs. Studies will also be completed which will more precisely
define the status of species of concern and identify critical
habitat areas for each target species. In Phase II studies will be
initiated to: 1) identify and quantify limiting factors, 2)
determine environmental requirements of the resident ichthyofauna;
and 3) measure responses of species of concern to experimental flow
regimes.

Phase III (1994-1997) will involve continuation of the Core
Research Programs which were initiated in Phases I and II, testing
of specific. hypotheses developed in the initial phases, and
monitoring effects of conservation measures that may be instituted.
Study designs for Phase III will be refined and implemented based
on findings in Phases I and II.
