QUALITATIVE (EVALUATED) ASSESSMENT - UNSPECIFIED |
Data Used to Assess Water Quality: |
Historically, spring-run and fall-run salmon and steelhead occurred in the Merced River. The spawning beds extended from the mouth of the river to Exchequer Dam, about 12 miles (G.H. Clark, 1929). Today, only the fall-run has survived. In 1852, Native Americans were observed harvesting salmon at Merced Falls. In November 1877, John Muir noted that salmon were abundant in deep pools. Unconfirmed reports suggest that both salmon and steelhead migrated as far up the South Fork as Wawona and in the mainstem as far as into Yosemite Valley. Reports from early residents along the river speak of high populations of fish coming up the river to spawn in the summer and fall.
In 1920, the Fish and Game Commission received a letter from a resident stating that there were fifty salmon in the past for each one now (1920). In 1928, a statement from Fish and Game said there were several hundred salmon in the fall. In 1961, the fall-run was described as poor. Estimates averaged about 250 salmon per year.
By the end of the six year drought, 1986-1992, escapement populations drastically declined believed to be attributed to low flow and elevated water temperatures during adult immigation and juvenile (smolt) spring-out migration from the Merced River. Between 1993 and 1998, salmon escapement improved when flow and water temperature improved. However, with the higher spring flows and cooler spring water of 1998 and 1999, the population has steadily declined since 2000. In 2000, fall-run salmon escapement numbers (over 13,000 spawners) have dramatically declined to only 2,000 spawners in 2006, a drop of about 84% below the year 2000 peak abundance.
There is a strong correlation between annual spring flow magnitude and future year adult production (Mesick and Marston 2007). As spring flow increases, smolt survival increases (CDFG Annual Reports). However, as temperatures begin to rise while salmon smolts out migrate, juveniles are still trying to migrate from the upper reach of the Merced River to the lower reaches of the Merced River, harming both critical life stages (Merced Irrigation District 1999-2005).
In addition to warm spring temperatures, the Department of Fish and Game submitted data to the Regional Water Quality Control Board regarding warm water temperatures present in the lower Merced River during the fall adult upstream migration season for the years 1998 thru 2005 (Tables 9 and 10 in CDFG¿s Letter to the RWQCB, 2007). Also, the Department of Fish and Game submitted data regarding warm water temperatures present in the lower Merced River spawning habitat reaches during the first half of the spawning season for years 1998 thru 2005 (Table 13 in CDFG¿s Letter to the RWQCB, 2007).
Steelhead in the Merced River are listed winter run. Juvenile rainbow trout have been caught in rotary screw traps out-migrating the Merced River. Anecdotal reports by anglers suggest that steelhead populations are good following years where summer rearing conditions are good (e.g. presence of cold water temperatures). State and Federal agencies believe their abundance trends mirrors those of salmon causing them to be listed as threatened in the Central Valley. The Department of Fish and Game submitted data to the Regional Water Quality Control Board regarding warm water temperatures present in the lower Merced River juvenile steelhead rearing reaches during the summer for years 1999 thru 2005 (Table 20 in CDFG¿s Letter to the RWQCB, 2007). |

Evaluation Guideline: |
In the absence of necessary data to interpret numeric water quality objectives, recent temperature monitoring data shall be compared to the temperature requirements of aquatic life in the water segment. In many cases, fisheries, particularly salmonids, represent the beneficial uses most sensitive to temperature. Information on current and historic conditions and distribution of sensitive beneficial uses (e.g., fishery resources) in the water segment is necessary, as well as recent temperature data reflective of conditions experienced by the most sensitive life stage of the aquatic life species. If temperature data from past (historic) periods corresponding to times when the beneficial use was fully supported are not available, information about presence/absence or abundance of sensitive aquatic life species shall be used to infer past (historic) temperature conditions if loss of habitat, diversions, toxic spills, and other factors are also listed.

Evaluation Guideline: |
Toxicity is defined as a statistically significant effect in the sample exposure compared to the control using EPA-recommended hypothesis testing. For SWAMP data exceedances are counted with the significant effect code SL. SL is defined as the result being significant compared to the negative control based on a statistical test, less than stated the alpha level, AND less than the evaluation threshold. This data set reports a simple pass/fail (Yes/NO) code to report toxicity that is equivalent to the SWAMP SL code. |
