 Provisional data warning, subject to revision
Realtime data presented on this web site -- including stream discharge, reservoir water levels, data from water quality monitors and meteorological data -- are preliminary and have not received final approval from agencies that are collecting it. Data relayed by satellite or other realtime telemetry have received little or no review. Inaccuracies in the data may be present because of instrument malfunctions or physical changes at the measurement site. Subsequent review may result in significant revisions to this data.

Users are cautioned to consider carefully the provisional and tenative nature of the information contained within this web site before using it for any decisions, particularly ones concerning personal or public safety or the conduct of business that involves substantial monetary or operational consequences. The agencies disclaim responsibility for the accuracy of this data until it has been reviewed, revised as necessary, and finally approved.

 Custom Data Requests

Historical data is available at the Columbia River DART (Data Access in Real Time), University of Washington. The DART Homepage has several categories of data that can be queried directly. If you are unable to locate the desired data at DART, it will be necessary to submit a custom data request.

We can respond to requests for data retrieval and customized reports for Corps of Engineers' project data on a case-by-case reimbursable basis.

Charges for retrieval and distribution of Northwestern Division data from our CROHMS database will use the applicable rates as published in the Portland District "Freedom of Information Processing Cost for Technical Data" rate sheet. Charges will only be for our actual time and materials. The current rate is $US19.40 per hour (one-half hour minimum).

Payment will be by MIPR (between Corps offices), or prepaid check made out to:
