Become a freshwater expert capable of using scientific knowledge to solve complex problems and protect valuable water resources.

More than 95% of our students land well-paying jobs in their chosen field or begin a PhD program. Our job placement rate is high because faculty and staff work with students to explore freshwater careers, build a network and develop the professional skills that will help them land a job.

Required career development coursework helps you develop essential leadership skills and build real-world connections through mock interviews, resume-building activities, elevator pitches and mentorships with industry leaders in water-related organizations.

An internship with a water-related business, government or nonprofit organization gives you the experiences and connections to launch your career while you’re still in school.

Our equipment and research vessels give you hands-on opportunities to build expertise you can only get in the field.

No GRE required for application. No thesis required for graduation.

You must meet Graduate School requirements in addition to the following to be considered for admission:

Bachelor’s Degree

A bachelor’s degree in biology, chemistry, economics, geosciences, mathematics, physics, public policy, or other appropriate natural science, social science or engineering discipline.

Undergraduate GPA

Applicant must have at least a 3.0 undergraduate GPA. All of an applicant’s undergraduate coursework completed before award of the first undergraduate degree is included in the GPA computation. For courses that were repeated for credit, each attempt is included.

Those whose undergraduate GPA is below 3.0 should contact Aaron Thiel, Graduate Program Manager, for guidance. Applicants may be considered for admission if they are able to provide evidence of their ability to succeed in graduate study.


All applicants, including UWM students, must upload an official or unofficial transcript into the Panthera admission application system for all work done at higher education/postsecondary institutions. All applicants who are admitted to the Graduate School will be required to submit an official transcript with the degree posted within two weeks of the beginning of their first semester of enrollment.

Reason Statement

The reason statement is an essential part of the application. It is used to determine the appropriateness of your educational and professional goals and serves as an example of your ability to express yourself in writing. Your reason statement should include:

  • your reasons for pursuing graduate study
  • your specific background interests and background in the field
  • any relevant skills or training you’ve acquired
  • any academic awards or honors you have received

Submit a current resume that clearly articulates your professional experience.

Writing Sample

Submit a scholarly writing sample that demonstrates critical thinking and writing skills.

Letters of Recommendation

Three letters of recommendation are required by persons who can attest to your scholarship and/or research potential and your success in graduate school at the School of Freshwater Sciences.

List of Relevant Coursework

List relevant courses taken at previous institutions. Please include course number, course title, credits and final grade (example: BioSci 150, Foundations of Biological Sciences, 4 credit, A-). The following prerequisites are strongly recommended:

  • at least one semester of any three of the following topical areas: chemistry, biological sciences, physics and calculus
  • one additional semester of chemistry, biological sciences or physics

The minimum degree requirement for the MS Aquatic Science (Professional) track is 32 graduate credits.

All students in the professional science track are required to participate in an internship research experience, generally between the first and second years of the program. Internship experiences focus on complex regional, national, and global water problems and often involve authentic, practical problems in the field. The program coordinators provide resources and internship opportunities with industry, government, and non-profit organizations. It is the responsibility of the student and advisor to identify the internship and the direct supervisor within a specific organization and submit a proposal that identifies goals and objectives of the internship. Proposals will be reviewed and approved by the advisor. Alternatively, a group project may occur in lieu of an internship and should provide students with training and experience in performing professional-level work that involves managing group dynamics and applying technical expertise to solve complex, multidisciplinary water-related problems.

Graduates of our MS professional programs have high job placement rates. More than 95% of those tracked are working in a water-related job or enrolled in a PhD program.
