UW-Madison limnology professor Stephen Carpenter discussed the lakes at the North American Lake Management Society symposium last week.
James Lorman, a biology professor at Edgewood College, said leaves, road salt, erosion sediment, geese and fertilizer runoff all increase phosphorus levels in the lake. The phosphorous is unlikely to leave.
The focus is more on preventing [phosphorus], not so much getting rid of it, because once its in the lake, there is not much you can take out, Lorman said.
Phosphorus is the primary cause of algae blooms in the lakes, and some toxic blooms can cause illness or death, Carpenter said.
The lake could be cleaned up a lot within 10 to 20 years by reducing erosion and phosphorus release, Carpenter said. The children of todays UW students would enjoy a clean lake when they attend UW a generation from now.
With cleaner lakes, future generations could better enjoy Madison, a city built on natural beauty, historian David Mollenhoff said.
While the rest of the country was marching to the trumpets of industrialization, Madison leaders were listening to the string sounds of beauty, scholarship and culture, he said.
Despite the lakes influence on residents, Madisonians have done a lot over the years to affect water quality, Mollenhoff said.
The greatest insult of all, was putting sewage in the lakes, he said.
Carpenter said the pollution can make the lakes unpleasant for boaters and swimmers, but that does not prevent Kellen OBrien, UW-Madison graduate, from taking advantage of the lakeshores.
I do enjoy skinny dipping, OBrien said. But every time I do so, I make sure to shower immediately after exiting.
OBrien said he primarily dips in the very sludgy Lake Mendota, but has also visited Lake Wingra, where, theres a lot of pretty gross seaweed and green slime.
UW-Madison senior Amy Sawyers also swims in the lakes, but said the pollution stops many from jumping in.
But according to Sawyers, the pollution provides an added element to the subculture of skinny-dippers at UW-Madison. Now its not just that youre skinny-dipping, Sawyers said. Its filth-dipping.
Just dump it over the side . . . huh?

Pardon my ignorance.
I bought a new M and do to the etech dealer losing his lease have not had any access to it for about a month while I await dealer # 2 to install the motor etc.
Anyhow my question is: where does the drain tube coming from the sink go? I thought maybe to the bilge.

Transom thru hull
Exits at a transom thru hull. If you install a bilge pump that is where you will no doubt -T- into as well. You might well consider putting a check valve( I do believe most of us have done this ) in the bilge hose as otherwise. . . .you could fill your bilge from the outside and cause your pump to run a lot more than desired
.
Actually, I installed two separate thru-hulls for my bilge pumps.
They are up alot higher than the sink's thru-hull and I put a little more 'hump', rather than a loop into the line to prevent water from coming in that way. There is probably somewhere between 1 and 2 feet of head in my system (closer to 1, I think)...
I'd be rather wary about using check valves. They will fail, its just a matter of time. Also, you need to understand that there is something keeping them closed, when the pump isn't running. What is that? I'm guessing that they are most commonly spring loaded. That means that the pump has to overcome the force of the spring. Well, the short of that is that the spring acts like additional head, reducing the thru-put of the pump...

Re: Pardon my ignorance.
Below deck, in the aft berth you will see two fabric covered lscrew-attached liners at the far end. Remove the lower one and you will see where the hose t's into the motorwell drain. Removing the upper one reveals the steering apparatus. Good to know where that stuff is I suspect. Let us know how things progress, both good and bad.Nickyd wrote:I bought a new M and do to the etech dealer losing his lease have not had any access to it for about a month while I await dealer # 2 to install the motor etc.
