The Department of Labor publishes prevailing wages for geographic zones called OES areas. Every U.S. county belongs to exactly one, and the wage floor applies across the whole area. A worker in Oakland gets the San Francisco metro wage, not a separate Oakland wage.

Prevailing Wage Guide for Hydrologists

Verify your worksite metro before comparing wages

Federal agencies and environmental consulting firms often employ hydrologists at field offices or project sites far from headquarters. The LCA must list the actual worksite location, and wages in Tallahassee or Columbia can be roughly half the floor in Washington, DC for the same role.

Watch for federal contractor title mismatches

Titles like Physical Scientist or Research Hydrologist are common at USGS, EPA, and federal contractors but sometimes get filed under adjacent SOC codes. Confirm your employer's LCA uses SOC 19-2043 so your offer is measured against the correct Hydrologists wage floor, not a lower-paying classification.

Exclude field stipends and project bonuses from base wage

Environmental consulting firms frequently pay field per diems, project completion bonuses, and vehicle allowances. DOL prevailing wage compliance is measured on the guaranteed base salary only. Bonuses and reimbursements do not count toward meeting the floor for your wage level.

Frequently Asked Questions

How does DOL set the prevailing wage for Hydrologists?

DOL sets prevailing wages using Occupational Employment and Wage Statistics survey data collected by the Bureau of Labor Statistics across hundreds of metropolitan and nonmetropolitan areas. For each area, DOL calculates four wage levels tied to experience and complexity. Employers sponsoring a Hydrologist must pay at least the level that matches the actual duties and supervision requirements of the offered position.

What do the four wage levels mean and how do I identify mine?

Level 1 covers entry-level or closely supervised roles, Level 2 covers qualified professionals working independently on standard tasks, Level 3 covers experienced specialists leading project components or mentoring others, and Level 4 covers senior or principal-level professionals with broad authority. Your level is determined by the actual job duties, not your title. Review your employer's LCA, which lists the wage level OFLC certified for the position, to confirm which level applies to your offer.

Why does the prevailing wage for the same Hydrologist role vary so much by city?

DOL calculates wages separately for each metropolitan statistical area using regional BLS survey data, so local labor market conditions drive the floor. A market like Washington, DC has a high concentration of federal agencies and federal contractors competing for hydrologists, pushing wages well above the national median. Smaller markets like Tallahassee reflect fewer employers and lower local competition. The LCA must list the actual worksite city, so the metro where you will physically work controls which wage floor applies, not your employer's headquarters.

What happens if my offer falls below the prevailing wage for a sponsored position?

If the offered salary is below the OFLC-certified wage level for the worksite metro, DOL will not certify the LCA, which means USCIS will not approve the H-1B or employment-based petition. For existing sponsored employees, paying below the certified wage can trigger back-wage liability and jeopardize the employer's ability to file future petitions. The offer must meet or exceed the prevailing wage before filing, not after.

How do I find and verify the prevailing wage for Hydrologists in a specific U.S. location?

Use the OFLC Wage Search tool, which lets you look up current prevailing wages by SOC code 19-2043 and metropolitan area. Enter the worksite metro, select the Hydrologists occupation, and review all four wage levels for that area. For roles requiring PERM labor certification, the employer must request a formal prevailing wage determination from OFLC. Migrate Mate also surfaces which employers have sponsored Hydrologist roles in specific metro areas, helping you identify active sponsors in the location you are targeting.
