Hydrologist salary & career outlook

Quality water is crucial for human survival. Hydrologists work to ensure that we have it. According to the Bureau of Labor Statistics, hydrologists study how water moves through and across our planet's crust. They study how precipitation affects river flows or groundwater levels, as well as the environmental impact of surface water and groundwater when it evaporates into the atmosphere or filters to the ocean. This requires determining how changes to the environment influence the quantity and quality of water, measuring and collecting samples, and writing reports on findings, among other things.

Becoming a hydrologist usually requires a master's degree with a focus on the natural sciences. Some states also require a license. Other important qualities for becoming a hydrologist, according to the BLS, include analytical, communication skills and interpersonal skills, as well as critical thinking and physical stamina.

Job outlook for hydrologists

There seems to be no shortage of jobs in the near future for hydrologists.

The BLS projects that employment of hydrologists will grow by 10 percent between 2012 and 2022, which is almost as fast as the 11 percent average for all occupations nationally. That is projected to result in approximately 800 new jobs.

Population growth and expanding into new areas are two possible explanations for the growth in the hydrologist field. Other explanations exist, though. Demand for hydrologists is expected to increase as a result of mining, construction and hydraulic fracturing. Environmental concerns associated with these activities, as well as global climate change, are likely to increase demand for hydrologists in the future.

Some states have traditionally strong hydrology industries, while others have been weaker in the past but are expected to grow in the future. According to the BLS, the U.S. states with the highest numbers of hydrologists employed, as of May 2013, were:

  • California
  • Washington
  • Colorado

The American metropolitan areas with the highest employment level of hydrologists as of May 2013, according to the BLS, were:

  • Denver - Aurora - Broomfield, CO
  • Minneapolis - St. Paul - Bloomington, MN-WI
  • Sacramento - Arden-Arcade - Roseville, CA

When it comes to growth, it's a much different story. Based on data collected by state labor departments and aggregated by Projections Central, the states with the highest expected growth for hydrologists through 2020 are:

  • Virginia: 33.7% projected growth
  • South Carolina: 26.9% projected growth
  • Michigan: 26.6% projected growth
  • Massachusetts: 26.2% projected growth
  • Louisiana: 25.5% projected growth

If you're interested in water, natural resources and how our society functions in the larger world, choosing to become a hydrologist could be a rewarding path in a growing field.
