BLM AIM AquADat Point Identification Information: Citation: Citation Information: Title: BLM AIM AquADat Point Originator: U.S. Department of Interior, Bureau of Land Management (BLM) Publication Date: 20210315 Publication Information: Publisher: Bureau of Land Management Online Linkage: https://gis.blm.gov/AIMDownload/LayerPackages/BLM_AIM_AquADat.zip Geospatial Data Presentation Form: vector digital data Description: Abstract: This feature class includes monitoring data collected nationally to understand the status, condition, and trend of resources on BLM lands. Data are collected in accordance with the BLM Assessment, Inventory, and Monitoring (AIM) Strategy. The AIM Strategy specifies a probabilistic sampling design, standard core indicators and methods, electronic data capture and management, and integration with remote sensing. Attributes include the BLM aquatic core indicators: pH, conductivity, temperature, pool depth, length, frequency, streambed particles sizes, bank stability and cover, floodplain connectivity, large woody debris, macroinvertebrate biological integrity, ocular estimates of vegetative type, cover, and structure and canopy cover. In addition, the contingent indicators of total nitrogen and phosphorous, turbidity, bank angle, thalweg depth profile and quantitative vegetation estimates (see Entity/Attribute Section for exact details on attributes). Data were collected and managed by BLM Field Offices, BLM Districts, and/or affiliated field crews with support from the BLM National Operations Center. Data are stored in a centralized database (AquADat) at the BLM National Operations Center. Purpose: This dataset was created to monitor the status, condition and trend of national BLM resources in accordance with BLM policies. The methodology used for the collection of these data can be found in TR 1735-2 (AIM National Aquatic Monitoring Framework: Field Protocol for Wadeable Lotic System). These data should not be used for statistical or spatial inferences without knowledge of how the sample design was drawn or without calculating spatial weights for the points based on the sample design.

This is a less frequently used metric of characterizing central tendency of substrate sizes, but is the main metric used by the EPA for determining relative bed stability. It is less variable than a D50 and more biologically meaningful because it is more influenced by fine sediment.
