Yes, the boat launch at Holter Dam is closed due to the federal government shutdown. Not to worry, all other ramps on The MO are open and functional.
We took a trip up there to take a look for ourselves. It is a little creepy with nobody camping up there. There are a few boats launching despite the closure. Nothing is blocked off, there is still access to the river, and I hear it’s still fishing quite well above the Wolf Creek Bridge.
Launch at the dam if you dare, but tread with caution as you are technically breaking the law. We are recomending that people launch elsewhere for the time being. We tried calling the posted number for more information about the closure. However, the phone number goes to an office that is also shut down with nobody available to answer questions.
