| Study Name | Extensive Riparian Status and Trends |
| EIM Data Entry Review Status | Reviewed |
| Study Type | General environmental study |
| Study Purpose | Documentation of the current status and future trends of maximum stream temperatures for perennial streams located on lands managed under the current Forest Practices Rules. These data will aid in the evaluation of the landscape scale effects of implementing the forest management prescriptions recommended in the 1999 Forests and Fish Report. |

| Study QA Project Plan Description | Continuous temperature monitoring of perennial fish-bearing and non-fish-bearing streams to assess thermal maximums. Water temperatures were continuously assessed at 30-minute intervals. Air temperature, riparian cover, large woody debris, and several channel metrics were also evaluated in this study. |
| Study QA Assessment Level | Level 5: Data Verified and Assessed for Usability in a Peer-Reviewed Study Report |
| Study Result Description | The report titled "Extensive Riparian Status and Trends Monitoring Program-Stream Temperature Phase I: Eastside Type F/S Monitoring Project Final Report" can be found on DNR's website: https://www.dnr.wa.gov/publications/fp_cmer_10_1001.pdf?6p7em |
| Study Comment | The Extensive Riparian Status and Trends Stream Temperature Monitoring study consists of three parts. One part of the study monitors stream temperatures in Type F, or fish-bearing, streams east of the Cascade crest (study location name beginning with ERST_EF). The other two parts monitor stream temperatures in Type F and in Type N, or non-fish-bearing, streams west of the Cascade crest (study location names beginning with ERST_WF and ERST_WN, respectively).
Data for the following locations are included in EIM, but not used in the final analysis or report: ERST_WF000580UW, ERST_WN000052DA, ERST_WN000052DW, ERST_WN000052UW, ERST_WN000102DA, ERST_WN000102DW, ERST_WN000102UW, ERST_WN000174DA, ERST_WN000174DW, ERST_WN000174EW, ERST_WN000174UW, ERST_WN000249DA, ERST_WN000249DW, ERST_WN000249UW, ERST_WN000342DA, ERST_WN000342DW, ERST_WN000342UW, ERST_WN000749DA, ERST_WN000749DW, ERST_WN000749UW, ERST_WN000866DA, ERST_WN000866DW, ERST_WN000866EW, ERST_WN000866UW, ERST_WN000870DA, ERST_WN000870DW, ERST_WN000870UW, ERST_WN000978DA, ERST_WN000978DW, ERST_WN000978EW, ERST_WN000978UW, ERST_WN001182DA, ERST_WN001182DW, ERST_WN001182EW, ERST_WN001182UW, ERST_WN001753DA, ERST_WN001753DW, and ERST_WN001753UW.
In September 2023, it was determined that the probe at location ERST_WN001255EW was likely exposed to the air and was reading air temperature instead of water temperature. The dataset was updated to qualify these suspect records. |
