BLM OR Fire Water Sources Point

Frequently-asked questions:


What does this data set describe?

Title:
BLM OR Fire Water Sources Point

Abstract:
This theme depicts sources of water for fire management purposes that are accessible by engines, water tenders, pumps, or helicopter buckets. Water sources that are identified are judged to be useable during the period of a normal fire season. This theme does not depict water for uses other than fire fighting. For example, potable water is not identified in this theme.

A natural or artificial standing (not flowing) body of water. This code therefore includes lakes, ponds, bays, estuaries, wetlands, and impoundments. UN Unclassified Water body. This code is used to represent water bodies that have not been classified. PS Springs Seeps and wells. An issue of water flowing from the earth onto the land or into a body of surface water. There is no distinction made between man made/enhanced and those which are natural therefore includes guzzler. Also includes standpipes and hydrants or any other point source of water.

    Appended data for BLM's Lakeview district after matching values to the data standard. Summary of data collection: A Summer Temporary Employee was hired for approximately 8 weeks funded by fire/fuels money to conduct a field inventory and verification of Fire water sources. We started with a copy of the fire_water_source.gdb database, then created domains for fields that would benefit from their use. We "GPS enabled" the database with Trimble GPS Analyst extension for ArcGIS 9.2. We broke the inventory effort out into several components for purposes of prioritizing the work. We received a list of existing sources from the Klamath office of ODF, and created a point theme from their legal descriptions. Where these points landed on BLM land near roads we determined to be of high priority to visit and capture attribute data and verify location. The next phase of the work was to perform an intersection of BLM roads and Perennial streams, and perform a "spatial select" on the centroids of perennial water bodies near roads on BLM lands. Points were located, GPS'ed, and attributed in ArcPad. The final phase of the work was to obtain a copy of the Oregon Water Resources Department's water rights geodatabase and find the BLM water rights on BLM land within the resource area. These points were also located, GPS'ed and attributed. In some instances where there was an existing point feature in the database that was well located, ArcPad and the GPS unit were only used for attribution of the point. In other cases the points from the water rights database or ODF's point were not located at the most convenient place to fill an engine or tender and so were relocated using ArcPad. Matt Cornachione performed nearly all of the GPS and GIS work, with some assistance from Mike Limb (Klamath Falls Resource Area GIS Coordinator). All GPS locating, attributing, and recording was performed using ArcPad 7.x on a Trimble GeoXT GPS unit.

    Appended data for BLM's Roseburg district after matching values to the data standard. Attribute values for field RIGHTS_NUM are known to be incomplete (they lack the prefix letter of either "P" or "R") and will be updated when possible by Roseburg district staff. Summary of data collection provided by Roseburg district: Location information for the water sources was obtained from Tom Lonie. This was in the form of township, range and section and in many cases GPS coordinates. This information was used as a guide in locating the points. In addition to this information, Digital Ortho Quads were used as a background for digitizing water source locations. When they were not visible Tom Lonie, Bob Gilster Judy Hyde and Tom Doss were asked to help locate them based on their field experience. The points were added by Dale Gough using Arcedit. Attributes were then added based on the infomation supplied by the before mentioned people.

    Forty five water sources, GPS'ed by DFPA, were added to the layer. In addition, attributes for POC_RESTRICT were updated based on testing for Phyophthora lateralis, completed by the BLM in 2009 and 2010. As per Kevin Carson's guidance (South River SMRS), only water sources with P. lateralis were considered contaminated. If other species of Phytophthora were encountered the water source was considered clean. As well, any water sources previously attributed as contaminated, that were tested and not found to have P. lateralis, were changed to clean.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    No data currently exists.

  5. How consistent are the relationships among the observations, including topology?

    Transaction level: This level of quality control occurs when a district has completed an update to the FWTR_SRC theme and the resulting data layer is provided back for inclusion into the corporate geodatabase. GIS topological checking is limited at check-in time since this is a point theme. This theme has ""required"" fields that must be populated prior to updating the theme in the geodatabase. All text field data must be filled out in upper case. Upon check-in, all attributes are checked to assure that they conform to the data standard.
