AQUATIC HABITAT AND FLOW CONDITIONS: Following the wettest January-February since at
least 1998, March was relatively dry with only 2.2 inches of rain although
river flows remained well above the long-term median. Flow conditions in the Carmel River were generally excellent
for migration and rearing of all steelhead life stages.
Mean daily streamflow at the Sleepy Hollow Weir ranged from 159 to
717 cfs (monthly mean 331 cfs) resulting in 20,350 acre-feet (AF) of
runoff. The Highway 1 gage was rewetted on December 9 and the March monthly
flow ranged from 229 to 651 cfs (monthly mean 378 cfs), resulting in 23,240
AF of runoff.
There were 2.17 inches of rainfall in March as recorded at
Cal-Am’s San Clemente gauge. The rainfall total for WY 2017 (which started on
October 1, 2016) is 30.23 inches, or 161% of the long-term year-to-date average
of 18.72 inches.
CARMEL RIVER
LAGOON: The lagoon began
filling December 9th and spilled on
its own (without mechanical breeching) through an outlet channel sculpted by
the County to the south on December 19th at ~14.2 feet water
surface elevation (WSE) above mean-sea-level (NAVD 1988
datum). During March 2017, the WSE ranged from approximately 4.6 –
12.8 feet above mean-sea-level (see graph below). By the end of March,
the lagoon mouth had moved back to the south.
Water-quality profiles were conducted at five lagoon sites on February 13th. Conditions were “good to excellent” with low salinity (< 4 ppt), and moderate dissolved oxygen (DO) levels (5-12 mg/l) and water temperatures (54-60 degrees Fahrenheit).
LOS PADRES DAM ADULT
COUNTS: Cal-Am began
their adult steelhead trap and truck operations at LPD on December 19,
2016. The first ocean-run adult steelhead since 2013 were trapped
and transported above the dam on February 2, 2017. By the end of March,
a total of five ocean-run steelhead and 24 resident fish (<16”, non-ocean
run) had been trapped and transported.
