Hydrologic Technician
As a Hydrologic Technician within the Washington Water Science Center, some of your specific duties will include:
Performs a full range of stream discharge measurements at all stages; Plots discharge measurements, develops stage-discharge, velocity index curves and/or complex ratings such as those used at culverts, gates, pumps, etc. and estimates extensive periods of missing record and non-routine flow of tidal, backwater, or ice periods. Performs and reviews statistical and/or technical analyses of a wide variety of hydrologic data collected in the field. Prepares and evaluates data reports of results of field activities, including the preparation of materials for publications, such as tables of data, maps, and other illustrative materials. Configures, installs, maintains and services a wide variety of sensing, recording and communications equipment and instrumentation. Operates a government vehicle as an incidental driver. Above duties are for the GS-09 level. For the lower grade levels, incumbent will perform a wide range of tasks described in the above duties, but at a lower level of work designed to further develop and refine the knowledge and skills of the incumbent. Assignments will typically combine productive work with on-going training and instruction. Supervision received at the lower level will be closer with oversight and review being provided more frequently Physical Demands:
The work regularly requires considerable dexterity, agility, and strenuous physical exertion such as that needed to:
climb, or work from, tall ladders or scaffolding; work in areas where footing is treacherous such as on slippery river banks, in steep or rocky terrain, and in fast-moving water; lift heavy objects weighing over 50 pounds or more; and crouch or crawl in constricted areas. Work Environment:
The work regularly involves moderate risks or discomforts associated with visiting field sites with limited access, under adverse weather or flooding conditions, or exposure to irritant or toxic chemicals. Work may require the use of special clothing or gear such as masks, coats, boots, googles, respirators, or life jackets. There are two vacancies; however, this announcement may be used to fill additional vacancies if they become available. For GS-09:
Applicants must meet one of the following to qualify for the GS-09 level:
Posses one year of specialized experience equivalent to at least the GS-08 level in the Federal service that is in or related to the duties of this position. Specialized experience may include work as a technician or aid in engineering, earth, physical, or natural science, forestry, soil conservation, or surveying; trades or crafts work in maintenance or construction of facilities or equipment related to hydrology; drafting; or construction estimating if it equipped the applicant with the knowledge, skills and abilities to perform successfully the duties of this position. Examples of GS-08 level assignments:
1) Installing, adjusting, inspecting, and servicing crest-stage indicators, well-recorders, and other instruments for the collection of ground and surface water data; and checking gage settings to ensure continuing accuracy of the records obtained from instruments; 2) Measuring stream discharge utilizing various devices; observing and noting conditions which may have a bearing on stage-discharge relationships; making and compiling observations of the fluctuations of ground water levels in designated wells; and collecting water samples for chemical analysis. For examples 1-2, the assignments involved working independently within the general instructions (related to scope, objectives, time limitations, priorities, etc.) provided at the outset of the assignment/project. Significant discretion was exercised in selecting from among a large variety of feasible alternatives. Approval was obtained prior to implementing significant deviations from established guides. Other examples of GS-08 level work assignments include:
1) Making reconnaissance surveys for the location of new river gaging stations; and preparing plans for gaging stations and such supporting equipment as automatic controls, cableways, and other accessories required for a complete stream-gaging facility; 2) Collecting data and preparing reports on the ground water levels. Data consists of quarterly and annual measurements of water levels in ground water observation wells, and measurement of the amount of ground water pumped from irrigation and other wells. For examples 1-2, work assignments involved some technical problems not previously encountered; problems involving concepts and methods for which guides and precedents existed, were resolved independently. General oral instructions relative to the time to be allotted to certain functions, expected time of completion of assignments, possible technical problems which may be encountered, and approaches that may be used in resolving these problems were provided. OR applicants may substitute successful completion of 2 years of progressively higher level graduate education (36 semester hours, 54 quarter hours or the equivalent) leading to a master's degree or possession of a master's degree in hydrology or other field of study directly related to the work of this position for the required 1 year of specialized experience if it provided the knowledge, skills, and abilities necessary to perform the work of this position. OR applicants may substitute a combination of appropriate specialized experience (as described above) and appropriate graduate level education (as described above) that is beyond the first 1 1/2 years of progressive graduate study to meet the qualification requirements. For GS-11:
Applicants must meet one of the following to qualify for the GS-11 level:
Possess one year of specialized experience equivalent to at least the GS-09 level in the Federal service that is in or related to the duties of this position. Specialized experience may include work as a technician or aid in engineering, earth, physical, or natural science, forestry, soil conservation, or surveying; trades or crafts work in maintenance or construction of facilities or equipment related to hydrology; drafting; or construction estimating if it equipped the applicant with the knowledge, skills and abilities to perform successfully the duties of this position.

For examples 1-2, assignments included responsibility for the development of the plans, assembly, analysis and evaluation of data, and the preparation of appropriate reports. There were opportunities for unreviewed decision making. Work was carried out with an unusual amount of autonomy and required the modification of applicable methods and techniques. Responsibilities included the resolution of problems that impeded the progress of the project, with cooperating agencies (state and federal) and private individuals. Other examples of GS-9 level assignments include:
1) Making reconnaissance surveys for the location of new river gaging stations; and preparing plans for gaging stations and such supporting equipment as automatic controls, cableways, and other accessories required for a complete stream-gaging facility; 2) Collecting data and preparing reports on the ground water levels.

Significant discretion was exercised in selecting from among a large variety of feasible alternatives. Approval was obtained prior to implementing significant deviations from established guidelines. OR applicants may substitute successful completion of 3 years of progressively higher level graduate education (54 semester hours, 81 quarter hours or the equivalent) leading to a PhD or equivalent doctoral degree in hydrology or other field of study directly related to the work of this position for the required 1 year of specialized experience if it provided the knowledge, skills, and abilities necessary to perform the work of this position. OR applicants may substitute a combination of appropriate specialized experience (as described above) and appropriate graduate level education (as described above) that is beyond the first 2 years of progressive graduate study to meet the qualification requirements. You must meet all qualification and eligibility requirements for the position by the closing date of the announcement.
