Name: Stream Monitoring

Display Field: SiteID

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This point feature class represents fixed sampling locations along creeks, tributaries, and drainage channels where the Environmental Services Department regularly collects water samples and performs environmental testing.Environmental Monitoring & Compliance Workflow:Program Purpose: Tracks long-term surface water quality trends, identifies illicit discharge impacts, and monitors ecological health across local watersheds (e.g., Big Bear Creek, Denton Creek tributaries).Testing Parameters: Used to record field measurements and laboratory analytical data including pH, dissolved oxygen, turbidity, conductivity, temperature, bacterial indicators, and pollutant concentrations.Maintenance & Update Frequency: Periodic / As Needed (Updated when new monitoring stations are established or sampling access locations change)Process Step (Lineage Description):Station Establishment: Sampling sites selected by Environmental Services staff based on watershed coverage, access considerations, and stormwater program requirements.Attribute Integration: Station IDs, stream names, watersheds, and monitoring program protocols populated and maintained within the enterprise geodatabase.
