Moriya-walleyeGrowing up, Moriya spent summers at her family’s cabin on Leech Lake in northern Minnesota. It was there that she first became fascinated with the many varieties of fish and insects that can be found in the lake. Spending so much time on the lake also helped her realize the importance of clean water in lakes and streams.

Her main interests in graduate school were the roles played by aquatic insects, and their presence as indicators of water quality and ecosystem health.  She earned a degree in aquatic entomology because she wanted to apply her enjoyment of collecting and identifying insects to real world problems and have her work create positive change in land management and water quality.

Now Moriya has 13 years experience working with lake associations, conducting lake monitoring programs and assessing lake water quality data. To date, Moriya and RMB staff have completed 274 lake and lakeshed evaluation reports for 15 counties and numerous lake summaries for lake associations.  In addition, Moriya and RMB staff train over 500 volunteers annually (2007-present) through the RMB Environmental Laboratories Lakes Monitoring Program.

She lives in Detroit Lakes with her husband and two children.
