| Topic | WQ: Dissolved Oxygen in Redwood Creek Below MBCSD 1999 |
| Caption: Dissolved oxygen (D.O.) concentrations were measured at three stations (below Muir Beach Community Services District (MBCSD) well , above Muir Beach Community Services District well, and above Highway One) in Redwood Creek in 1999. This graph shows those measurements taken below the MBCSD well site. The reference values represent the minimum Cold water habitat (7.0 mg/L) and Warm water habitat (5.0 mg/L) criteria from the San Francisco Bay Regional Water Quality Control Board 1995 Basin Plan (CRWQCB, 1995). Dissolved oxygen concentrations at this point were above the Warm water criterion, although they did dip below those optimal for salmonids. The sags in D.O. are companion with low flow conditions which allow pools to stagnate. D.O. readings from automated probes may be artificially low if detritus or decaying organic material gets caught on the sensor. Data were provided by the Golden Gate National Recreation Area. See Map for water quality monitoring locations and Info Links for more information. | |
