If you recreate on the water, it is your responsibility to know and understand the no-wake rules in effect on Montana waters. That includes operators of personal watercraft.
In general, the same rules apply to all types of watercraft.
Here is a quick rundown on no-wake zones.
No-wake zones are in effect on all lakes and reservoirs in the state west of the Continental Divide in the Western Fishing District. Also, all commercial marinas have no-wake zones near their facilities. These rules help reduce the impact of vessel traffic on the shoreline, boat marinas, other recreators and residents with lakeside property.
"No-wake" means a vessel must travel at a speed where there is no "white" water in the track or path of the vessel, or in waves created by the vessel.
All watercraft operating on public lakes and reservoirs under 35 acres in the Western Fishing District are limited to traveling at no-wake speed. A list of these waters is available on the Montana Fish, Wildlife & Parks website at fwp.mt.gov.
On waters greater than 35 surface acres west of the Continental Divide, watercraft must travel at no-wake speed from the shoreline to 200 feet from the shoreline. Exceptions are:
o Crystal Lake
o Horseshoe Lake
o Loon Lake
o Lower Thompson Lake
o McGregor Lake
o Middle Thompson Lake
o Upper lobe of Upper Thompson Lake
