Since 1999, the Hubbard Lake Sportsman and Improvement Assoc. has put 800+ fish shelters in Hubbard Lake. We are investigating the condition and design of these structures to see if changes are needed. We are also researching how they are performing as structure for all aquatic organisms, especially fish. Invasive species are also being recorded. Students and teachers are assisting with ROV and GPS technology. A local dive team is also assisting. Two field days were held in 2013, with more planned for 2014. Parameters were established, and videos, pictures, and visual reports will provide information we need to decide on further action for this fish structure program.
