General Concerns
Proposed narrative or stepped numeric standards
would relax required temperature standards during
critical spawning and incubation periods
• Spring spawners
• Cutthroat trout (CS-I)
• Rainbow trout (CS-II)
• Fall spawners
• Brook trout (CS-I)
• Brown trout (CS-II)
• Mountain whitefish (CS-II)
How is WQCD’s proposal
different than winter shoulder
season excursion?
All excursions address 303(d) listing decision
• DON’T list due to abnormally low flows
• DON’T list due to abnormally high air temperatures
• DON’T list due to abnormally warm spring or abnormally
warm fall (shoulder season excursion).
NO assumption that high temperatures due to these conditions
are protective of aquatic life.
Ovary and Sperm Development
• High water temperature during spawning inhibited
ovulation and decreased % survival to hatch
(Taranger and Hansen 1993, Jobling et al 1995)
• Thermal stress reduces oocytes ability to form egg
yolk (King and Pankhurst 2003)
Fertilization
• When fertilization occurs at elevated temperatures
larval survival is reduced (Van Der Kraak and Pankhusrt
1997)
• (Alavi and Cosson 2005) Increase in temperature…
• Increased initial velocity
• Decreased the percentage of motile spermatozoa
• Significantly decreased the total duration of forward
movement between 14-21 oC
Embryo Development
• At 15 oC or more, rainbow trout embryo quality
was poor (Billard 1985)
• The period of optimum egg viability is shortened
by elevated temperatures (Van Der Kraak and
Pankhurst 1997)
What triggers spawning?
• Photoperiod
• Temperature
For Salmonids
• Photoperiod is most important
• temperature secondary
(Van Der Kraak and Pankhurst 1996, Bye 1984)
Salmonidae - Rainbow Trout
Spawning in Colorado River (Nehring 1988)
April 20-May 10
• Viable levels of ovulation, egg production, and survival to
eyed stage occurs 9-15oC (9-12 oC is optimal) (Pankhurst et
al 1996).

Concerns
Does not provide adequately long or cold enough
winter for successful spawning of thermally
sensitive warm-water species.
Current standard may not provide adequate
protection for incubating eggs of spring spawners
What triggers spawning?
• Photoperiod
• Temperature
In general…
• Centrarchids- Photoperiod and temperature equally
important (Kaya and Hasler 1972)
• Cyprinids - mixed
• Golden shiners - Long photoperiods and warm
temperatures are required to induces spawning (de
Valming 1975).
Cyprinidae
Lake chub (Ahsan 1966)
• low temperatures (5–12 °C) are essential for normal gonadal
proliferation and formation of the primary spermatocytes.
Goldfish (Gillet et al 1978)
• High temperatures (20 and 30 oC) in spring blocked oogenesis
Carp (Davies et al 1986)
• Unseasonal elevation in temperature resulted in failure to ovulate
Golden Shiner (De Vlaming 1975).
• Cold temperatures trigger egg and sperm development
Moronidae – Striped Bass
Females constantly exposed to warm water (18 °C), with or
without a natural photoperiod cycle (Clark et al 2005)
• diminished levels of hormones that trigger yolk
formation
• Reduction in egg size
• premature degeneration of ovaries
Percidae – Yellow Perch
yellow perch
•Growth phase of the
ovaries is during
winter
•Optimum gonad
maturation occurred
at 6oC or lower for
185 days
Jones et al 1977
via Hokanson 1977
Percidae – Yellow Perch
•Optimum gonad maturation occurred at 6oC or lower
for 183 days (Krieger et al 1983)
•A winter minimum of 10 oC is near the upper limit,
for a minimum of 145 days (Krieger et al 1983)

• Conclusions supported by field data (Miller 1967).

• Explore heat removal treatment options –
Feasibility study being explored by WQCD.
