#ARMY CORPS LOCK QUEUE REPORT SERIES#
In practice the decision support analyst or user can now generate time series datasets on any lock by entering its identifying information into the program (EROC code, river code, and lock number). Users now have access to integrated, time series datasets relevant to lock unavailability and the reasons for it. Even without weather data the ability to adjust Lock Performance to continuous rather than annual operation represents a marked change in navigation decision support provided by NDC. It was an achieved objective of this use case to provide lock usage data collected on a better-than-annual basis that can be linked with anything else measured in time. Non-Commercial Vessels, Flotillas, and LockagesĪs exact times of unavailabilities are known, it is now possible to control for things such as weather.Barges Empty and Loaded, Commercial Vessels, Flotillas, and Lockages.Data are arranged inside of tables such that columns represent calendar years, and rows represent the following usage variables The second sheet contains tables for All Waterways, each individual waterway, and every Waterway Lock.
Its first sheet is Table of Contents – Locks by Waterway. The currently available, downloadable report has File Name: Lock Usage CY 1993-2019.XLXS “A flashback query allows you to view data as it existed at a previous point in time. They are described with the following columns: Avg Processing in Minutes (Past 24 Hours),.Information is organized into nine (9) reports that include a Lock Queue Report with the following Selection Criteria: “Select a river system and a lock, then click the Submit button to view a report of the most recent vessel traffic reported at the lock.” waterways that transited a Corps-owned or operated lock structure.” flag vessels and foreign vessels operating in U.S.
The information contained here represents an every 15-minute updated snapshot of Freedom of Information Act (FOIA) data on U.S. “The Corps Locks website contains lock and vessel information derived from the United States Army Corps of Engineers Lock Performance Monitoring System (LPMS). research centers and investigators (e.g., MarTREC),.There is an opportunity to make this kind of analysis possible by systematically collecting data from the Corps Locks website Target User(s) ¶ The objective of this use case is to show how external variables can help decision support analysts to better understand variation in lock usage given datasets that are high-resolution with respect to both place and time. Because these data are reported on an annual basis it is not possible to do any meaningful analysis of lock usage with respect to seasonality and weather including surface – water data (e.g., streamflow and gage height). The goal and context of this use case is to provide navigation decision support via more detailed descriptions about vessels operating in US waterways, and usage of locks by vessel type.įor example, the Public Lock Usage Report generated by LPMS is a summary of lock usage by vessel type, by year. Its primary purpose is to act as a planning tool for vessel operators.
NDC provides information on locks through the Lock Performance Monitoring System (LPMS). Navigation decision support to the US Army Corps of Engineers (USACE) is provided by the Navigation Civil Works Decision Support Center (NDC).
