# barr_BlockageLU

BlockageExtent:
Temporary (landslide; woody debris, etc.)


# barr_SignifLU

BarrSignif:
Temporary, but presently prevents introgression


# BARRIER

Comment:
Seasonal Barrier, sunshine supply ditch diversion dam


Comment:
Falls did not effect historic distribution


Comment:
Headcut vertical drop Scheduled to be corrected
If not corrected treat cutthroat above as separate pop.


Comment:
Not viewed as historic waterfall
Did not restrict historic distribution

Comments:
This mapping segment includes 4 complete barriers


Comments:
Current population abundance associated with level of stocking.   Chemicals used to remove brook and rainbow trout.

Comments:
Segments 16 and 17 on hard copy map are combined in database


Comments:
Two complete barriers on this stream segment


Comments:
Segments 24 and 25 on hard copy map merged in database.


Comments:
lower portions of this segment abundance is rare - fish are larger
with in lower portion there are a number of temporary barriers not identified as barriers in database


Comments:
Water diversion, development, bomb shelter


# FishPres Genetic Risk LU

Activity:
Hybridizing species CANNOT INTERACT with population.  Barrier provides complete blockage to upstream fish movement.


Activity:
Hybridizing species are in same stream and/or drainage FURTHER THAN 10 KM from population, but not in same stream segment as population, or WITHIN 10 KM WHERE BARRIER EXISTS, BUT MAY FAIL.


Activity:
Hybridizing species are in same stream and/or drainage WITHIN 10 KM of population and NO BARRIER EXISTS; however, hybridizing species not in same area as population.


Activity:
Hybridizing species are SYMPATRIC with population in same stream segment.

# FishPresGeneticsLU

GeneticsDesc:
Genetically unaltered (>99.0%) - tested via electrophoresis or DNA


GeneticsDesc:
Introgressed (hybridized) - tested and found to be 75% to 99% YCT


GeneticsDesc:
Introgressed (hybridized) - tested and found to be less than 75% YCT


GeneticsDesc:
Potentially unaltered with no record of stocking or contaminating species present


GeneticsDesc:
Suspected hybridized with records of contaminating species being stocked or occurring in stream


GeneticsDesc:
Hybridized and Pure populations exist in stream (use only if reproductive isolation is suspected)


# HistoricalLU

Description:
Habitat limited - gradient, elevation, temperature


Description:
Known geologic barrier at lower boundary


# RISK Isolation Risk LU

Criteria:
Migratory forms must be present and migration corridors are open (connectivity maintained).


Criteria:
Migratory forms are present, but connection with other migratory populations disrupted at a frequency that allows only occasional spawning.


Criteria:
Questionable whether migratory form exists within connected habitat; however, possible infrequent straying of adults from other populations into area occupied by population.


Criteria:
Population is isolated from any other population segment, usually due to barrier, but may be related to lack of movement or distance to nearest population.


# RISK Pop Demograph Risk LU

Criteria:
Population is increasing or fluctuating around an equalibrium that fills available habitat that is near potential. No nonnative competing or predating species present.


Criteria:
Population has been reduced from potential, but fluctuating around an equalibrium (population relatively stable and either habitat quality is less than potential, or another factor - disease, competition, etc. - is limiting the population).


Criteria:
Population has been reduced and is declining (year-class failures are periodic; competition may be reducing survival; habitat limiting population).


Criteria:
Population has been much reduced and has either been declining over a long time period or has been declining at a fast rate over a short time-period (year-class failures are common; competition or habitat dramatically reducing survival).
