Applicants must meet one of the following to qualify for the GS-6 level:
One year of specialized experience equivalent to at least the GS-05 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-05 level work assignments: 1) Computing mean daily gage heights from water stage record charts, editing record tapes, and making corrections based on field observation notes; 2) Preparing maps showing well elevations and depth to water, hydrographs, profiles, and well locations. For examples 1-2, the 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. Other examples of GS-05 level work assignments include: 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) Making technical studies of hydrologic data collected in the field, and preparing material for publication, such as, drafts, maps and other illustrative material; applying datum corrections to gage height records allowing for periods of ice effect, temperature variations, and precipitation; and plotting hydrographs and analyzing differences in hydrographs with earlier records, and making necessary changes. For examples 1-2, routine assignments that involved familiar conditions, concepts, and methods were made in terms of the objectives to be achieved without explicit instruction as to work methods. Assignments involving new, more difficult, or unfamiliar areas of work were given with more specific guidance. Explicit instructions were provided for solving technical problems involving unfamiliar conditions, methods, or concepts.

**OR applicants may substitute successful completion of 1 year of appropriate graduate level education (18 semester hours, 27 quarter hours or the equivalent) 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 1/2 year of progressive graduate study to meet the qualification requirements.

Applicants must meet one of the following to qualify for the GS-07 level:
