As you may have seen in previous editions of Genoa News and Notes, the coldwater production building on the north end of the hatchery grounds (hence, Coldwater North) received a major makeover last year. What was once gravel and fiberglass is now manicured concrete, and a once sleepy artesian well can now double its output with the aid of a booster pump. What all this means is our Coaster Brook Trout program now has a new permanent home. We are now able to raise two year classes side by side in the same building and the fish can remain there throughout their time at the hatchery. We fully put the new setup to the test in March, cranking up the pump and moving nearly 13,000 7” trout into the raceways to go along with their 1” roommates currently living in circular tanks. Zach Kumlin has been busy at work reestablishing our alarm system and troubleshooting any bugs in the system. This building will help us achieve the Service’s goal of producing quality Coaster Brook Trout for Lake Superior and tribal waters for years to come.
