What stands out for hydrologic technicians
The clearest signals from the latest validated score, outlook and metro data.
Current demand is the strongest component
Current demand scores 50/100, compared with 25/100 for occupation fundamentals, a 25-point difference.
JobMarketHealth score componentsLong-term employment is projected to contract
BLS projects 400 average annual openings and -1.3% employment growth from 2025 to 2035. Projected openings are a modeled annual average, not vacancies open today.
BLS Employment ProjectionsLargest published metro market
Orlando-Kissimmee-Sanford, FL has the largest published metro employment count for hydrologic technicians, at 110 jobs. The next-largest published metro is Houston-Pasadena-The Woodlands, TX with 100 jobs. This measures employment scale, not market quality.

How to read this section
QCEW measures employment and wages by industry, not by occupation. We weight those industry conditions using the published industry mix for this occupation. These figures describe the industries that employ this occupation; they are not direct counts of people working in the occupation or jobs currently open.

Compare states for hydrologic techniciansSide-by-side published industry conditions for two or three states. There is no state-level health score; the 0 to 100 score is national.
How to read this page
The score is a national composite from 0 to 100 that weights near term hiring demand at 50 percent, the occupation's own employment fundamentals at 30 percent, and long-term outlook at 20 percent. Wages and occupation profile details are context shown alongside it, not score inputs. See the full methodology.
Median annual wage and metro employment come from BLS OEWS, which is annual. Projected annual openings and projected growth come from BLS Employment Projections and describe the published projection horizon, so they are not a count of jobs open today. Values shown as not published are suppressed by the source rather than filled in here.

AI & this occupation
How AI relates to Hydrologic technicians work
Across 2 research exposure measures, Hydrologic technicians is in the higher technical AI exposure band based on the mean of the available source-specific percentile ranks. Exposure describes how much of the work the studied AI capabilities could technically assist with; it is not a forecast of job loss.
JobMarketHealth has not measured an AI effect on this occupation's employment or wages, and these figures do not enter its scores; there is no clear evidence of displacement in the data shown here.
Exposure measures (kept separate)
- GPTs are GPTs exposure (β, GPT-4 rated): 0.50 of 1, national percentile 78 (higher third)
- Microsoft AI applicability: 0.23 of 1, national percentile 77 (higher third)
National context: what businesses used generative AI for
From the Census 2025-26 BTOS AI Supplement (all industries; businesses whose employees used generative AI). Census did not measure Hydrologic technicians specifically.
- Writing or editing documents, emails, or communications: 85.4%
- Searching for information or technical help: 49.9%
- Interpreting, analyzing, translating, or summarizing documents: 44.6%
- Information processing, paperwork, or filing: 34.7%
Exposure and observed usage are separate measures and neither equals job loss. Census BTOS figures are business-level surveys and are not occupation-specific. Sources: GPTs are GPTs occupation exposure; Microsoft Working with AI: AI applicability; Census BTOS Core AI Use; Census BTOS AI Supplement 2025-26.
