So, after spending millions of dollars and inspecting tens of thousands of boats in CA, has a single mussel been found at any lake in CA? Has the spending been justified, or a total waste?

I've had my boat inspected at Del Valle, San Pablo, Coyote, Santa Margarita, Casitas, Perris, Diamond Valley, Clear Lake, and at the California border with Arizona. At most of those locations I've asked the inspectors if they've ever found anything. In every case the answer has been no.

One inspector actually told me that if they did find something, they would send the person home and not report it to the water district because even a single finding could scare the district bad enoguh to close the lake completely. Which would mean they would lose their job. This is a classic . Given this, can we even expect that if mussels are found they will be reported? I would reason that in most cases they will not be reported.

The most likely scenario I see for mussel infestation in Northern California is via a house boat or similar large vessel that comes from an infested location like Mead or Havasu. I watched the woman who inspected my boat when I crossed the CA border coming from Missouri. Water could have been in my lower unit or in the livewell and she would never have found it. I doubt she knew what a livewell was or where to find one in a boat. The inspection was a joke compared to what they put you through at DVL or Coyote. If my next stop was a place like Don Pedro, McClure, Melones, San Antonio, Nacimiento, Clear Lake, Oroville, the CA Delta and Shasta where there are no inspections or joke inspections (Clear Lake) the mussel would get in.

The second most likely scenario to my mind is that the mussels will come from a boat in San Diego that launches at one of those large water bodies named above. That one is a no brainer since lakes like Lower Otay and El Capitan have mussels and there's nothing to stop people from driving straight to a place like Don Pedro and launching. They dump the bilge when they get there and off go the mussels.

We all know that most of those large lakes listed above drain to the CA Delta. So as soon as one is infested, the Delta is only a matter of time. Stopping the mussels from getting downstream will be as futile as or stopping . Those programs make fun work for biologists and headlines in the newspaper but they don't work. They just waste a lot of money that could have been spent doing something useful things like creating fish habitat or cleaning up garbage on the shore of the lake. Just imagine if all the quagga mussel inspectors in the state had been cleaning up trash and planting fish habitat instead of sticking their finger up drain plugs.

I see mussel infestation in the CA Delta is inevitable. When it does happen the question will then be, "What's next?" Water from the Delta flows all over the state. It may be possible to treat and filter to these 'downstream' locations and keep the mussels out, but at what cost? Would it be cheaper to just open up boating at all lakes again and let the mussels go where they may?

Is it cheaper to install equipment at the lakes to deal with the mussels than to inspect for them for year after year? Has anyone done a cost-benefit analysis here? Or was the California response to the dreaded mussel infestation just a knee-jerk reaction based on ignorance of the facts? Here's a map showing mussel locations across the country.

Should we feel pity for everyone around the great lakes and points south that are infested by the mussel? I mean, their lives must be terrible, right?. Or should we have a reality check and look at the well known fact that the only time any humans have lost water in the United States because of mussels was in Monroe, MI in 1989 for 2 days. Time for a reality check people.

Mussel infestation across California is inevitable. The results will not be disastrous. Fishing will be fine. Drinking water will be fine. The only disaster is continuing to harass boaters and pour money down the drain inspecting boats. The water districts should just save the money for the day when they have to start filtering for mussels. If they had started two years ago they'd have a nice chunk of change saved up already.

I agree with your last comment. It's not possible that all water agencies are staffed with idiots, and it is likely that their decisions are highly influenced by money factors. Clearly there is a collective belief in inspections among CA agencies. I don't know why all the other states in the country don't care. This could be an area for more research.

This line did make me laugh, "In most cases it's not clear what these estimates and projections are based on, and whether they are limited to facilities costs or include secondary or environmental costs.

It seems likely that these studies and estimates are coming from phD's at research universities. phD's have a reputation for being smart, but then again most of my professors in grad school were phD's and not all of them were smart.

I wish I had more time to thoroughly research this topic and interview people.

Here's San Luis Obispo's assessment of the mussel situation.

If you don't think there's a bias against bass fishermen, read the section below and note that there is no mention of water skiiers, jet skiiers, or pontoon boats. All of those boats are welcome at Lake Lopez. Ever heard of a wake boat ballast system? .

LOCAL CONCERNS

Lopez Lake and Santa Margarita Lake are at greatest risk during a bass fishing tournament. Bass boats travel from lake to lake competing and can potentially expose our lakes to QMs and their larva.

If a bass boat enters a tournament at a QM infested lake, they could carry the adult mussel or larva to one of our regional lakes.
Out of county boaters are of equal contamination risk (especially if recently visiting Lake Mead, the Colorado River, or any other infected water body).

Vessels docked or stored at non-infested lakes pose very little to no threat of spreading QMs. Also, vessels that are NOT introduced to infested lakes pose little to no threat of spreading QMs.

Has anyone been able to find anything on how these critters handle tidal water. I would imagine not to well since every six hours a good percentage of them would die off for being high and dry. Its also my understanding calcium plays a big roll in there survival. I would really be interested to know anything out there on robs pets getting into the delta. Would they actually survive? I have looked but I am not the google expert as nico is.

CA DFG did an assessment of potential mussel success based on calcium levels at lakes around the state.

From everything I can tell the mussels would have no problem living in the fresh water portions of the Delta. They don't live in saltwater.

The Delta has what they call a hydrological barrier during the summer months. Basically a narrow section of the Delta where the water goes from fresh to salt. This is maintained through releases from the lakes upstream. So the dividing line of mussel infestation would probably be right along that hydrological barrier (a few miles of distance down past Sherman).

I think that pretty much sums it up right there. I used to get worked up over natural resource issues. However, Im not in a position to make REAL change and I got sick and tired of swimming upstream, so I dont pay attention to it anymore. Life is short; my time is better spent pursuing things that make me happy.
