Hydrologist I/II

Lower Colorado River Authority

LaGrange, TX, United States 🇺🇸

General Overview

At an entry level, performs hydrologic data collection; analysis and reporting;  construction, operation and maintenance of field instruments and equipment; and/or support of reservoir operations for water supply and flood control.  Assists River Operations Center (ROC) to manage decisions about reservoir and river functions.  This position develops competence, knowledge and experience in own discipline.  Utilizes discretion and independent judgment to determine an appropriate approach within general parameters and some guidance from supervisor, manager and/or more experienced colleagues. 

 

  • Collects and monitors hydrologic data and observations, including stage/discharge measurements, reference elevation marks, high water marks, point of zero flow, channel and control section conditions, evaporation, diversions, water use data, and other information as directed.
  • Constructs and maintains field instruments, including O&M records for stream flow and precipitation monitoring stations, sensors, data logger/transmitters, telecommunications equipment and other equipment as directed.
  • Supports flood operations.  Compiles information needed for flood briefings.  Determines flood gate settings, heights of water above spillways, and hydro-generation operations to pass required flows.
  • Educates residents on lake and river operations.  Communicates and explains water supply, flood conditions and water control decisions to internal and external partners and customers. 
  • Performs hydrologic and hydraulic studies relative to regulation of stream flow.  Estimates real-time tributary inflows and gains in flow to the Colorado River below the Highland Lakes.  Determines minimum release of water required from the Highland Lakes.
  • Schedules hydro operations for flood control, water delivery, hydropower production and hydroelectric plant maintenance needs.  Provides daily and seasonal forecasts of available hydroelectric energy.
  • Compiles information needed for water use allocations, water use reporting, and regulatory compliance.  Assists to analyze data and prepare reports.
  • Gathers hydrologic data and performs field analysis by traveling independently or with other staff to various locations as necessary.

At an intermediate level, designs, manages, and participates in hydrologic field studies.  Maintains the hydrologic aspects of LCRA’s Hydromet System.  Directs field data collection activities.  Independently performs hydrologic data analysis and computer modeling for flood control, database programming and maintenance, and weather monitoring.  This position utilizes knowledge and experience in own discipline but is still building higher-level knowledge and skills.  Utilizes discretion and independent judgment to determine an appropriate approach within general parameters and some guidance from supervisor, manager and/or more experienced colleagues.

  • Performs analysis of field and office hydrologic data collection activities and observations, including stage/discharge measurements, reference elevation marks, high water marks, point of zero flow, channel and control section conditions, evaporation, diversions, water use data, and other information as directed.
  • Directs the maintenance of field instruments, including O&M records for stream flow and precipitation monitoring stations, sensors, data logger/transmitters, telecommunications equipment and other equipment as directed.
  • Supports flood operations.  Coordinates information needed for flood briefings.  Schedules hydro operations for flood control, water delivery, energy production and hydroelectric plant maintenance.  Oversees and contributes to after-action reports following major and minor flood events.
  • Educates residents on lake and river operations.  Communicates and explains water supply, flood conditions and water control decisions to internal and external partners and customers. 
  • Develops and implements hydrologic forecast models utilizing real-time Hydromet data.  Demonstrates skill in assessing and using digital precipitation estimates to forecast runoff.
  • Performs hydrologic and hydraulic studies relative to regulation of stream flow.  Estimates real-time tributary inflows and gains in flow to the Colorado River below the Highland Lakes.  Provides guidance on determining minimum release of water required from the Highland Lakes.
  • Coordinates with National Weather Service field offices and River Forecast Center to obtain weather and stream forecasts to use in public advisory and lake operations and forecasts.
  • Gathers hydrologic data and performs field analysis by traveling independently or with other staff to various locations as necessary.
