samiam it is clear that locals only is saying exactly that and it is true. Algae was an issue then but the weeds weren't. We didn't have to clear the prop of weeds then. It is true that leaving out of Corinthian Bay we would sometimes have to motor out quite a way from shore to find water less filled with algae and when we changed out of our suits we would find our bodies peppered with it; but weeds were a Highland Springs thing not a Clear Lake problem
Cite a source.[quote]"Biologists say the weeds have been here since the beginning." [/quote]Is insufficient evidence. Also misleading since yes, weeds and lakes go hand in hand, but the weed "Problem" is relatively new. Anyone who has lived here AND used the lake regularly over the last several decades will tell you that.
Personally I am inclined to go with the primary source here.
As for the DDT comment, well that was just silly.
When doing research on the history of the lake I prefer science to "redneck testimonials". So exactly how do you define "problem"? I guess when the naturally occurring plant life interferes with your ability to pollute the lake with your powerboat or makes it harder for you to trick and torture the fish then that is what makes them a problem right? You remind me of the people who site a hot day as evidence of global warming. The fact that we didn't have as many weeds in the lake during the 70s as we do now is not evidence of a problem. It just tells us that the lake has more weeds in some years than in others. Not exactly a world shaking revelation.
If anyone desires information about the history and health of the lake I would urge them to contact Dr. Harry Lyons at the community college in Clearlake.

As for my ddt comment I have no problem with it. It's the same ignorant people who continue to use poison like ddt long after it's been shown to be ruining our environment that insist that the naturally occurring weeds in our lake need to be poisoned to make our recreational activities a little more convenient.

In the late fifties early sixties Clear Lake was used as a test site for for DDD. It was to replace DDT. It was applied 3 times in a five year period to control the gnats. The algea and small fish absorbed it into their system but not a lethal doses. The birds and larger fish ate the algea and smaller fish and did get a lethal dose. The test was a failure and DDD was not approved Does anyone remember the large scale fish die offs in the early to mid sixties. The study was conducted by UC Berkely. I read the report in 1996. I do believe that large scale clear cut logging in the early 1900's and the agriculture have had an affect on the lake.

And let us not forget that we had wetlands ALL around the rim of the Lake - these filter out excess nutrients. I've seen footage of the lake where you couldn't tell where land stopped and lake started because of the vital, vibrant wetland vegetation. We've pretty well stripped that vast majority of that with private boat ramps, Caltrans on 20 and folks who ripped out their tules and planted those damn palm trees like this is SoCal for their private beaches. The only fun part is when they find out that their private beach stops at the high water mark on Rumsey and anything below that is open to public access - as long as you don't cross private property to get there.

The fertilizer that you apply to your lawn and garden runs off into the lake and feeds the weeds.
Tax it and use the money to maintain the lake. Simple.

Anybody wanna by some DDT? This is the good stuff, not that watered down stuff they sell over in Colusa County. Best price guaranteed. Meet me behind the garage @ midnight. Bring some Keystone Light.

REPEATER - This meeting has nothing to do with EPA / Superfund activities in the OAks or Elsewhere. Exclusively Helen Mine in Dry Creek headwaters. Attend anyway.
SAMIAM - Some weeds are invasive. This years' crop of Milfoil (Long stringy, anchored at base, has float capsules in leaves) is coming out strong in mid-lake areas - Subjective observation, this. Hydrilla is disastrously invasive, but others don't belong either and should be treated. Dr. Lyons recommend is great info and fun too.

If the county was really interested in saving the lake , they would have boat inspection teams at the launch ramps. Daily there are many many boats entering the lake with no inspections. Try visiting redbud park on a week end.

Born and raised in Lakeport. I have lived 20 feet from the lake for most of my life. This weed problem started in the 1990s. To listen to an educated guess about the weeds and how they have been here before that is BS. Listen to the long-timers and ask the indians.

Oh goodie...more testimonials, and all know how reliable the indians are as a historical resource.

Samiam, not sure if you had a chance to take a look at the Clear Lake integrated watershed management plan released a few months ago (you can ftp a copy of the document from the following link

It has a pretty substantial amount of information (200 pgs) on the algae and weeds.
I would agree with you about Harry Lyons, he is a wealth of knowledge and he also backs up the facts with his personal experience over the years. I am wondering if there are any activities you enjoy doing on the lake as you do not appear to be a boater, fisherman, or swimmer.

Well it seems some of you have not been here that long. Check photo archives before the 1990s (Huh, what? Algae, but no weeds) on Clear Lake. Could this be the same lake?

With all the postings no one has addressed the fact that boats are being allowed on the lake with NO INSPECTION at all. Guess the caretakers of the Lake will as usual wait until it is too late then cry the blues.

dredge the shallow areas of lake, making them deep so the sunlight does not penetrate, 8 ft uv light does reach past that

Carp spawn? With the Quagga ranger's citation money. We will be policing the lake this weekend come join the party.

Basic and to the point, this lake will be overwelmed with invasive plants and life. There is plants growing a mile out from Lakeport at 14 feet deep. A foot longer and they will surface. At the rate of water being taken out of the dam we will see them on top in a week or two. Already dead carp stuck in the weeds. Watch as our tourism shrinks even more. At least Anthony F is trying to do something about this problem.
