Increased flows from Lake Tahoe come before snow melt begins in earnest. More storms – although not as strong as previous storms – are expected to continue through the weekend adding additional precipitation and snowpack to the Tahoe and Truckee River basins. Tahoe stands four feet above its rim and 2 feet below its maximum elevation dictated by court decree. Tahoe has risen above its maximum elevation during periods of extreme precipitation events such as occurred in 1997.

Fluoridated water for Truckee Meadows not solution

A bill, AB 193, that just had a Nevada Assembly Committee hearing last Tuesday, would mandate that the Truckee Meadows Water Authority (TMWA) add fluoride to our community’s high quality drinking water.  The bill should come again before the Assembly Natural Resources Committee; reports are that the committee members appeared favorable to the Legislation.
