Meet The Milfoil Crew Captains

The LEA milfoil crew will be back in action this season! We will continue our work on Long Lake, Brandy Pond, the Songo River, and the northern parts of Sebago Lake. We are fortunate to have three returning captains again this year. They will be on the water every day, teaching newer crew members how our program operates and ensuring that everything runs smoothly. Our crew leaders are friendly, knowledgeable, and deeply committed to their work. If you spot one of our teams out on the water, any one of our captains will be happy to answer your questions about our work to control invasive variable-leaf milfoil.


Walker joined LEA in 2017 as a courtesy boat inspector and then transitioned to the milfoil program before becoming a crew captain. Being from Naples and Bridgton, working with LEA on the local rivers and lakes has been very meaningful to him. He’s had the opportunity to work with great people, make lifelong connections, and have a positive impact on the environment he grew up in. Outside of LEA, his passion lies in music. Walker has been performing in various bands since high school, and recently graduated from Wheaton College with a major in music. After the milfoil season this year, he plans to pursue a career in education and composition. Walker is grateful for the opportunities and experiences LEA has provided him and plans to spend his summers on the milfoil boat for as long as he can.


Alec graduated with a double major in Environmental Science and Environmental Studies from the University of New England. This will be his 5th season with the milfoil team. In the off-season, he works as a math teacher at Kennett High School in North Conway, NH. He lives in Conway with his wife, two kids, and dog. Alec and his family try to get outside as much as possible. He loves hunting, fishing, mountain biking, rock and ice climbing, and paddling.


Morgan started on the LEA milfoil crew in 2021 and is now entering her fourth season, and second as a captain! She grew up and still lives in Sebago, and graduated from Lake Region High School in 2020. She’s an avid outdoorswoman and enjoys fly fishing, hunting, and hiking with her father and grandfather. Needless to say, protecting and preserving this area is very important to Morgan! In the off-season, she works as a ski technician and spends a lot of time skiing at Pleasant Mountain. Some of her other hobbies include singing, playing the flute, camping, and cooking. She looks forward to this season, and can’t wait to get back to diving!
