Observed pay change
What changed, BLS OEWS 2019–2025
- The published national median for Hydrologists moved from $81,270 in May 2019 to $96,600 in May 2025 (+18.9%).

Hydrologists (SOC 19-2043) has a national median of $96,600 per year in the BLS Occupational Employment and Wage Statistics May 2025 release. The published 10th-to-90th-percentile boundaries run from $64,020 to $153,130, and the published mean is $103,600. Those summary statistics describe the estimated distribution; their difference alone does not identify its cause. OEWS estimates 5,850 jobs in covered establishments nationally. WageDex has published rows for 34 state or territory areas and 37 metropolitan or nonmetropolitan wage areas. The published national median moved from $92,060 in the May 2024 OEWS release to $96,600 in May 2025, a rise of $4,540 (+4.9%). This is a change between two BLS survey estimates, not an inflation-adjusted same-worker pay raise.
BLS Employment Projections forecast a -0.1% change in employment from 2024 to 2034, which we classify as declining relative to the all-occupations baseline of 3.1%. About 500 openings are projected per year from growth, occupational transfers, and labor-force exits. BLS assigns Bachelor's degree as typical education needed for entry. BLS does not publish a separate occupation-specific fatality and injury rate for this role in the current release. The safety panel below shows its broad Life, Physical, and Social Science Occupations SOC-group context and is not an occupation-level measurement or ranking.
Geographic variation matters as much as the headline median. Maryland pays the highest state median at $143,010, which is +48% above the national figure. The highest published metropolitan-area median in this ranking is Washington-Arlington-Alexandria, DC-VA-MD-WV at $152,730. The observed difference does not identify its cause. Pair the national median with the state and metropolitan-area rows below while keeping the geography and statistic consistent. OEWS includes tips, commissions, incentive pay, and production bonuses, but not employer benefits, overtime premiums, stock compensation, or nonproduction bonuses.

Across the 11 releases WageDex holds for this occupation, the published national median went from $79,550 in May 2015 to $96,600 in May 2025. Within the SOC-2018 classification (2019–2025), the like-for-like change averages +2.9% per year in nominal terms. Within the same SOC classification, estimated employment went from 6,440 in May 2019 to 5,850 in May 2025.
Each figure is a separate BLS survey estimate, so a change between releases reflects the estimated occupation-wide median in each year. It is not the raise any individual worker received, and it is not adjusted for inflation. Years where BLS did not publish an annual median for this occupation are omitted rather than filled in. This span also crosses a classification change: releases before May 2019 use the 2010 Standard Occupational Classification and later releases use the 2018 SOC, so figures either side of that boundary are not strictly like-for-like. Headline change rates on this page use only the same-classification subset.

How to use Hydrologists pay figures in a real decision
- The 75th-percentile wage is about $122,830/year. Treat it as the upper-quartile market boundary, not an automatic target for experience alone; role scope, location, industry, credentials, performance, and employer context still need separate evidence. Salary calculator
- Location moves pay significantly: Maryland leads at $143,010/year for this role. Weigh state pay against local cost of living before relocating or negotiating remote. Pay by state
- Compare this occupation against similar roles before you decide, so you are reading the pay band in context rather than in isolation. Compare jobs
