| Study Name | Continuous Stream Monitoring |
| EIM Data Entry Review Status | Not Reviewed |
| Study Type | General environmental study |
| Study Purpose | Collect diel continuous water and air temperatures statewide at most of Ecology's Ambient Stream Monitoring Stations (June - September). The data may be used to evaluate compliance with state water quality standards and interpret a station's monthly temperature data. |

| Study QA Planning Level | LEVEL 4: Approved QAPP or SAP. |
| Study QA Project Plan Description | The accuracy and instrument bias of each temperature logger is verified through pre- and post-deployment calibration checks. Temperature loggers and a certified reference thermometer are tested in controlled water baths that bracket the expected monitoring range (near 0º C and near 20ºC). Monthly checks are conducted with a reference thermometer during deployment only at ambient stations. |
| Study QA Assessment Level | Level 5: Data Verified and Assessed for Usability in a Peer-Reviewed Study Report |
| Study Result Description | Point temperature measurements recorded at 30 minute monitoring intervals. |
| Study Comment | The stream water temperature data may have periods of data gaps caused by instrument malfunction or from the logger being exposed to air when flows drop below the deployment location. Data with gaps during the critical summer period may not represent seasonal maxima. |
