The Monitoring Location Registry (MLR) is the first stop in the workflow for establishing a new NWIS Site. In this session we will review the MLR workflow, solicit ideas for improving it, and brainstorm on ways to leverage and enhance MLR to simplify the process of establishing sites in SIMS, AQTS, and AQS. The desired outcome is a roughly prioritized list of MLR improvements and ideas for ways to improve the overall Establish Site Workflow.
