Reno ’99: Planning Progress

Planning is rapidly moving ahead for Reno ’99.   At least the time is rapidly passing!

The preliminary brochure has been mailed to about 13,000 people.
Through a combined and twisted effort we have a colorful logo for Reno that fits the theme:
Water: 21st Century Gold.

Also, check it out in color at

Thanks go to Paul Beaty, Doug Ball, Terry Thiessen and Bill Taylor.

The Reno Hilton, an excellent site for a large conference, has been explored several times by various members of the conference committee. Fund raising (sponsors and exhibitors) need a boost; check it out in the Reno ’99 story below. Development of the technical program will soon become a frantic effort.

Abstracts are due by June 1.


Reno ’99: We Need Your Help, and It is Easy!

CALMS has committed to host the Reno ’99 NALMS conference. There are several areas that require your assistance. In order for CALMS to make money or avoid losing money, the NALMS Conference must make money. The financial success of the conference depends upon sponsors, exhibitors, and good attendance.

You can help by reviewing your contact lists for potential sponsors and exhibitors. There certainly are businesses servicing your work place or business that could use the exposure afforded by a national (international) lake management conference that will be attended by 600 to 800 people. This is the first time NALMS has met in this region; it is a golden opportunity.

There is a brochure available that describes many levels of sponsorship and the value to the sponsor for that support. Contact Terry Thiessen <>, Bill Taylor <> or Hugh Marx <> with your prospective contacts and for copies of the brochures. Any level of support is helpful. Sponsorship is usually more successful when contact is first made by an associate. Terry Thiessen will do all the follow-up work. The same benefits apply to exhibitors.

Go get 'em! It is important.

Reno '99:  Call for Papers

The call for papers for Reno ’99, the NALMS annual symposium, is out.

Abstracts are due June 1, 1999. Check out the NALMS website at for abstract details.
REMEMBER that this is an opportunity to emphasize western water issues.
We want as much participation from CALMS members as possible.

If you want to chair a session or organize a session contact
  Alex Horne <> or
  Bill Taylor <>.

If you don’t want to present a paper, be sure to attend.
The NALMS conferences are extremely valuable to lake and watershed managers, lake associations and the general public with an interest in the local lakes.


On-Site Reno '99 Assistance

As the Reno conference draws nearer, volunteer support will be required for various functions such as the Clean Lakes 5K Run, logistics, gofers, registration, set-up, tear-down, etc.
Keep it in mind, we will be calling.


The CALMS annual conference will be at Reno ’99 this year as part of the NALMS conference.
Make plans to be in Reno December 1-4, 1999.

Mitten Crabs Invade San Francisco Bay

By Pete Alexander

Just when you thought it was safe to go back in the water! One of the latest introductions into the San Francisco Bay estuary is a crab native to Korea and China! But unlike most of the species introduced into this international shipping port every year, the Chinese Mitten Crab is a freshwater organism, which only inhabits salt water for breeding and the initial development of its young.

First discovered in the bay in 1992, the crabs were soon found in several of the larger streams feeding the south bay. It wasn’t long until they were found in lakes and reservoirs nearby. Anglers are often the first to notice them along the shoreline or lakes or streams or feeding on their bait! They are the only freshwater crab in the U.S. and not easily confused with crayfish.

The mitten crab resembles the familiar Dungeness crab found along our west coast, however, the mitten crab is smaller and its carapace is not as wide. Its most distinguishing characteristic is a prominent tuft of cilia just behind each pincer. This mitten-like growth is thought to aid the crab in filtering out sediment which might otherwise clog its gills. The crab is often found in high turbidity aquatic environments and may be found burrowing into banks and levees.

The Sacramento - San Joaquin delta system is riddled with levees which protect valuable farmland. The threat to the levees is only one impact of this creature.

The mitten crab also constitutes a significant change in the food chain within our freshwater and estuarine systems. Its impacts on aquatic invertebrates which comprise the food base for many native fish and wildlife species is yet to be ascertained as are its impacts directly to fish and aquatic vegetation. Currently they are a nuisance to bait anglers and have caused serious clogging problems on the fish screens at the Delta State Water Project where over 20,000 crabs have already been removed in one day during the fall migration.

The mitten crab has already been found as far north as Colusa in the Sacramento River drainage and as far south as Highway 165 in the San Joaquin River. It is only a matter of time before this species will be found inhabiting all but the coldest freshwater streams, lakes and reservoirs within one hundred miles access of the Pacific Ocean along the coast of California.

At this time there are no sound plans to control or eradicate this species.

In the mean time, keep your bait off the bottom and your toes moving!
