Jaclyn McCasland

Delaware Nation - Region 6


Jaclyn McCasland is the Environmental Director for the Delaware Nation Environmental Programs (DNEP). She oversees grant work such as GAP, CWA 106, and CAA 103. DNEP monitors surface water in their tribal jurisdiction in southwest Oklahoma that includes six counties. Jaclyn also manages the emergency management aspect for Delaware Nation as well as the Lenape Gardens and Farmers Market. She began her time as Environmental Director in 2019 and since then, DNEP has recently acquired the honor of serving as Region 6 representative for the National Tribal Water Council, as Region 6 representative for the National EPA-Tribal Science Council, and as the secretary for the Tribal Environmental Coalition of Oklahoma. Though she is fairly new to the tribal environmental realm, she hopes to use her passion, education, and cultural background to support Delaware Nation’s environmental mission. She has a Bachelor’s of Chemistry and a Bachelor’s of Biology with a minor in Mathematics. She was awarded the 2018 Gladys Anderson Emerson Undergraduate Research Award for her undergrad research endorsement: “Evaluation of Surface Water Resource Management Tools” and was recently published with her mentor and research partners in the Journal of Laboratory Chemical Education for their work at the University of Science and Arts of Oklahoma, Dual Role of 2,4-Dinitrophenyl Acetic Acid as Analyte and Indicator in Conventional Acid-Base Titration. With USAO’s great generosity, she hopes to continue to conduct research in the organic chemistry area for practical uses in the environmental sciences. She is from Anadarko, Oklahoma and loves being involved in her community through her work at the Delaware Nation as well as volunteering for community events as an Executive Board member of the Anadarko Chamber of Commerce. She enjoys taking part in events with her tribe and looks forward to her daughter’s time as Delaware Nation Princess 2022-2023. Much of their family time is spent outdoors and going to her son’s basketball, baseball, and soccer games. She also loves hiking, kayaking, and camping. She enjoys watching her kids grow and become individuals. She looks forward to serving this Council and learning the needs of our Region 6 Tribes and Pueblos.
