AQUATIC HABITAT AND FLOW CONDITIONS: During June 2011, Carmel River streamflow conditions for fish migration were adequate for all life stages of steelhead, with the exception of adult migration, which may become marginal below 80 cubic feet per second (cfs). A storm event hit the central coast on June 5 and increased river flows to a daily average of 201 cfs as recorded at the Monterey Peninsula Water Management District (MPWMD or District) Highway 1 gage. By June 16, river flow decreased to a daily average of 76 cfs, and out-migration for adults became marginal throughout the rest of the month.
During June 2011, the mean daily
streamflow recorded at the District’s Carmel River at Sleepy Hollow Weir gaging
station averaged 86 cfs and ranged from 51 to 235 cfs.
Unimpaired runoff at San Clemente
Dam (SCD) for the month of June 2011 was 5,202 AF. Unimpaired runoff at SCD for
Water Year (WY) 2011, which starts on October 1, 2010 has totaled 97,812 AF or
about 142% of the long-term annual average of 68,900 AF. During June
2011, 1.29 inches of rainfall were recorded at California American Water’s (CAW)
SCD. The rainfall total for WY 2011 is 24.73
inches, which is 115% of the long-term annual average of
