Layer: TierII Baseline Stations 2024 (0)

Name: TierII Baseline Stations 2024

Display Field: SITEYR

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This point dataset represents baseline Tier II MBSS stations used to designate each high quality Tier II stream segment within the State of Maryland. Each point represents either one benthic macroinvertebrate station location or one fish station location. This dataset currently contains 440 points, based on data collected between 1995 – 2021.

Layer: TierII Stream Segments 2024 (1)

Name: TierII Stream Segments 2024

Display Field: T2_SGMT_ID

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: This dataset consists of a digital geospatial representation of all identified Tier II segments in the State of Maryland. Based on data collected between 1995-2021, this dataset currently contains information for 269 designated Tier II stream segments. Main segment breakpoints were determined using the 100,000:1 National Hydrography Dataset (NHD). The final designated Tier II segments are the merged sub segments that make up the 24,000:1 NHD meeting the 100,000:1 breakpoints. Tier II stream segments generally terminate at confluences, impoundment outfalls, and tidal boundaries.

Layer: TierII AC Catchments 2024 (2)

Name: TierII AC Catchments 2024

Display Field: CATCHMENT

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset represents the ‘nested’ Tier II catchments, or watersheds located within the State of Maryland. Oftentimes multiple designated Tier II streams (with their own individual watersheds) occur within a common, larger watershed. Nested catchments are those watersheds whose surface areas drain to the most downstream Tier II stream segment in a collective watershed area. Based on data collected between 1995-2021, this dataset currently contains information for 201 Tier II catchments.
