AQUATIC HABITAT AND FLOW CONDITIONS:  Unseasonably high river flows in April kept conditions in the Carmel River excellent for migration and rearing of all steelhead life stages.

Mean daily streamflow at the Sleepy Hollow Weir ranged from 159 to 428 cfs (monthly mean 224 cfs) resulting in 13,340 acre-feet (AF) of runoff. Mean daily streamflow at Highway 1 gage ranged from 194 to 335 cfs (monthly mean 250 cfs), resulting in 14,880 AF of runoff.

There were 1.91 inches of rainfall in April as recorded at Cal-Am’s San Clemente gauge. The rainfall total for WY 2017 (which started on October 1, 2016) is 32.14 inches, or 158% of the long-term year-to-date average of 20.39 inches. 

 CARMEL RIVER LAGOON:  During April, the WSE ranged from approximately 4.0 – 10.5 feet above mean-sea-level (see graph below).  

 

Water-quality profiles were conducted at five lagoon sites on April 27th. Conditions were “good to excellent” with low to moderate salinity (0-17 ppt), and moderate dissolved oxygen (DO) levels (3-10 mg/l) and water temperatures (55-62 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 April, a total of seven ocean-run steelhead and 30 resident fish (<16”, non-ocean run) had been trapped and transported.
