Boat Decontamination

So, the State of Utah is starting a new decontamination procedure for boats leaving Lake Powell. They have worked with an entrepreneur to install and test a tank that contains fresh water heated to 110F which is looped through a heater. The intent is for you to back your boat into the tank, submerge all water inlets, run the engine, fill the ballast bags, empty the bags, and you are on your way 8-15 minutes later. Is anyone else concerned with running your engine in 110F water? This is certainly faster than the current fake-a-lake method with hot water washers, but I don't want to use this system if it ruins something on the boat. Any thoughts?

Your engine runs hotter than 110F...so you would be putting water through the system that is colder than the engines normal operating temp..

One word: thermostat!

There is nothing in your boat that would be hurt by 110F water...

Utah will give up on this soon.

All lakes get the clam lol

yeah 110 isn't going to hurt anything. Your hot water faucet puts out 120-140.

My worry is that the engine's cooling system is designed around water typically at most 20 degrees cooler and usually more than 30-40 degrees cooler. The idea is to dump a bunch of energy from the engine to the water using a heat exchanger. Cooler water makes for a less efficient heat exchanger. I guess since the engine won't be under load, it shouldn't be an issue, but wanted to see if anyone has had issues in hot water.

Your engine will be plenty safe even of it ran in the 230’s, you will be safe.

The fix is to prevent bad legislation before it is enacted. Law makers are so removed from the laws they enact so nothing changes for awhile. Organizations have lobbyists to attempt to steer law makers in a certain direction.

That would suck for G3 ballast owners with Enzos....filling and draining is close to 30 mins [emoji28]

Ha, I don't mind the 30 min when on the lake with a beer in my hand, but sitting at the launch waiting to go home.....

Exactly. When I'm done for the day, I'm done. I ain't gonna sit there in front of the game warden twiddling my thumbs while sterilizing zebra mussel jizz.

Granted, 110f may not burn you, but that tank looks like an accident waiting to happen.

If only a slip and fall into 110f water.

Seems pointless if the lake already has the clam in it.

I don't think the point is iradicating a lake of an invasive species, more so prevent the spread to other lakes.

In Texas, some lakes have been overrun with zebra mussels and some are pristine.

In reality, there are far more fishing boats than wakeboats so invasive species are being spread by livewells, not ballast systems.

Let Bass Pro sponsor some bullshit for that and leave us be.

As everyone else said, the 110 degree water won't hurt anything, and it's not hot enough to scald an adult, or kid either. Hot tubs get 106 and people sit in them for extended periods. I do anyway. Try to look on the bright side. At least this will help keep the water scum lines off your boat and rinse out your cooling system and ballast bags of water deposit buildups. Wonder if they put any type of mild cleaner in it? I can see the wait being a pain. Especially if 6 or 7 people are lined up to go through.

It is supposed to only take about 5 minutes which is a lot quicker than the current system they have. This will actually be much more efficient. Also more effective. I’ve been decontaminated with the current systems they have and honestly some of the people doing it I don’t think know what they are doing.

Truth!!!!

Lazy ass fisherman don’t believe it’s a problem until the mussels F-up the spawning ground, pH, etc., and totally wreck the ecosystem.

A-holes will yell at us shaking their Keystone Light grippers from shore declaring wake boats the are the evil of all evil without ever considering their own ignorance and egos.

Not saying all wake boaters are saints, but many are more saintly than the all-mighty down-rigging douche.

thinkin the same thing. been on the water for a long time- not as long as some others but... I would bet $1 that per capita, there are just as many a$$hats sporting wakeboats as fishing boats. there are a TON more fishing boats out there so it would make sense you see more but I bet if you level the field, it's similar.

I think RC is really onto the past root cause. we never ventured to many other bodies of water other than the couple lakes we frequent but I knew several fishermen that were going to tournaments all over the place. I would suspect that they have spread more than wakeboat owners in history but at this point it doesn't really matter. both boat styles are just as capable of spreading them and should be treated the same IF you are going to run a cleaning station.

State of Utah goes through all boats, including kayaks for invasive species checks. If you fish, they will go through all your tackle. They also look at anchor lines, inflatables, etc. if you have been on Lake Powell. As others have mentioned, this is about keeping mussels out of other lakes, since they are not showing up. Only one other lake has had suspected contamination and after 5 years, they have now marked it clean. They run road blocks outside Lake Powell in the summer and you have to show your mussel inspection certificate or you get a hefty fine. However, I was down at the lake this weekend and it is a big fishing tournament weekend and there were no decontamination people or inspectors in Hall's Crossing Marina (the least busy of the marinas currently open). Eventually mussels will spread to enough lakes that they will give up, but for now, if you only run your boat in waters outside of Powell, it is minimally invasive and you just have to answer questions. If you go to Powell, you are inspected before you leave and are required to decontaminate either before you leave or before you launch in your next lake. If you show evidence of contamination during the inspection, you must be decontaminated prior to leaving. I had fragments of quagga shells last year and they required decontamination of my cooling system, but for some reason didn't require me to decontaminate my ballast system.

I guess if you have ramfill (centurion?) than you cant get decontamination stickers? How would you clean that system given it fills and drains while underway at cruising speed?

Granted, you are backing the boat into a fairly shallow water pit, I am not sure if the boat is fully floating, but adding 3500# of mass while the boat is on the trailer doesn’t sound like a great idea.

A centurion would need to pull out of the pit to drain ballast and that would be so hard on truck and trailer.

Seems like an automated on board system that would spray clam killer into ballast tanks would be a worthy investment.

If such a system doesn’t exist, perhaps a worthy invention.

it'd never sell:) still have to get inspected for compliance so you're stuck there anyway and most lakes don't seem to care about this so it's a very limited market at this point.
I don't see the fees being charged for invasive ever going away as it's a cash grab the dnr/parks-rec are now counting on in budgeting but at some point as others have mentioned every lake will have them so the need to clean will diminish.
