Lack of rain creating challenges at boat launches this summer
The abnormally dry to drought conditions occurring across Minnesota are creating challenging conditions for people trying to get their boats into or out of the water at public boat launches, according to the Minnesota Department of Natural Resources.
When water levels drop during extended dry periods, the concrete ramps at boat launches may no longer reach all the way into the water and hazards such as prop-wash holes can become more problematic.
Prop-wash holes are caused by “power-loading” the boat onto the trailer instead of using the preferred method of cranking it on the trailer by winch. When water levels are low, people are more likely to back their trailer past the ramp’s end and into a prop-wash hole if one is present.
“It can be pretty difficult to get a trailer unstuck from a hole like that,” said Nancy Stewart, DNR water recreation consultant. “And just beyond the prop-wash hole, there’s often a mound of material that boats may get stuck on after launching, preventing them from getting to deeper water.”
Extending ramps can help in some places, but not when shallow water persists beyond the boat ramp. Stewart offers the following tips for launching boats in low water conditions:
Check the ramp, especially the firmness of the gravel at the ramp’s end, and the water depth.
Visit an alternative access site, or a different lake or river altogether, if water levels are too low to safely launch your boat.
Watch for obstructions in the lake, like large boulders or tree stumps.
Expect delays at public boat launches and be patient with boaters who are having difficulty launching. You can also #BeGoodNatured and offer assistance.

DNR assessing flathead catfish
Fisheries crews out of DNR’s Lake City station have been busy assessing the population of flathead catfish in portions of the Mississippi River and its backwaters.
The fisheries crew uses low-frequency electrofishing, which can reach a distance of 30 feet and only stuns the fish, leaving the fisheries crew to chase it down with the boat and net it on the move.
Biologists collect information on length, weight and aging structures from the sampled fish, to help them better understand the overall state of the fishery.
The largest flathead cat by weight caught in Minnesota waters was a 70-pound fish pulled from the St. Croix River in 1970. The Minnesota catch-and-release state record flathead cat was 52 1/2 inches long with a 32-inch girth, also from the St. Croix.
