To assess the migratory patterns of lamprey in the Penobscot, we propose a radio telemetry assessment around Milford Dam, the first major impoundment on the Penobscot River. This builds on the work carried out in 2020 and 2021 to assess passage at the first main-stem dam in the system. We intend to use Lotek MST-820-T radio tags to determine movement patterns (e.g., rate of passage, duration of delays, etc.) of fish that have passed Milford Dam. These tags are similar in size to those used in other lamprey studies on the Penobscot.
