Using event data in analysis and Using event data in analysis and reportingreporting::
How Oregon BLM Uses Event OverlayHow Oregon BLM Uses Event Overlay
First version of Aquatic Resource Information Management System (ARIMS) database deploys in 2000. Used ArcView and Informix. Uses Linear Events on routed line-work (LLID system)
Decision is made in 2006 to switch to NHD data model for PNW Framework Hydrography. Forest Service and BLM are main drivers.
Development of Hydro Event Management (HEM) tools begins in 2007 with Forest Service event-maker app as starting point.
ARIMS redesigned to use HEM and NHD in ARCGIS 9 environment in 2008
Legacy event data (millions of records) are migrated to NHD and HEM format in 2008-2009
Subsequent HEM development with EPA and USGS support add enhancements to system.
HEM and ARIMS work together in ARCGIS environment to manage aquatic data stored as events on the NHD route system.
All event data and NHD data used for linear referencing stored in same SDE Oracle instance
Deployed on Citrix server farm Users located in central, district, and
field offices.
Fish Distribution Riparian Wetland Condition Stream Surveys /Geomorphology Flow characteristics Water Quality Data
Criteria from multiple event tables needed to calculate riparian buffer distance
BLM Fishbearing Status
BLM Flow for Planning
Selection for varying buffer distances can be made easily when both events’ attributes are on same set of flowlines
("PLANFLOW" = 'I' or "PLANFLOW" = 'P' ) and "FISHBEARING" = 'ANV'
Need to be able to select and report miles of stream by fish presence, riparian condition, periodicity, etc.
Can’t have duplicate copies of geometry (no double-reporting miles)
Some of the data is temporal so need to extract most recent information
ARCGIS Event Overlay – Not line on line geometry overlay. Event overlay uses tabular route and measure info to INTERSECT or UNION event tables thus adding new fields from each successive overlay.
Oracle PL/SQL Analytical Queries – Used to analyze temporal event data to bring most recent records forward into publication dataset. Riparian Functioning data (PFC) and Fish presence data are processed this way.

Much of the fisheries work done by this requirement of Whole Stream Identifiers. Much of the fisheries work done by this agency is in collaboration with other pacific nw states. The fundamental organizing agency is in collaboration with other pacific nw states. The fundamental organizing unit for their data management is the full river. We are exploring the possibility of unit for their data management is the full river.

Example of Livestock Direct from Source
Amount of time to place all dams estimated at over a year.
• Automate the process as much as possible.• Use multiple sources and their spatial relationships.
Successfully automated the placement of over 23K (55%) of the water right dams to NHD.
• Only 20K dams and 140K more surface water right points of diversion to go.
• Attribute the dams
• Continue to investigate referencing additional means of diversion types (significant effort; not as easy to place as dams; may not have as much success automating).
