Prepare Your Yard for Cold Days!

Key Tip: It's time to cut down your watering

As we start moving through October, temperatures will begin to cool down. When this happens, our plants, trees, and grasses start to transition and need less water. Your watering schedule should cool down to help your landscape naturally go into dormancy.

Begin by reducing sprinkler run times or dropping a day off your weekly watering schedule. Then, as chilly mornings turn into colder days, you can slow down watering to once a week or less.

When grass growth slows down, your yard is moving into dormancy for the winter. In this phase, too little water near your root systems is better than too much! Your grass is dormant when it has stopped growing. This is when sprinkler systems can be shut off for the winter.

Don’t forget to drain and disconnect all outdoor hoses and winterize your sprinkler system before the first hard freeze. Truckee Meadows Water Authority has a short video to guide you through the process at www.tmwa.com/howto.

Truckee River and Tahoe Basins: Daily Water Update

Daily SNOTEL Basin Index

Year-to-date indexes represent % of normal snow water equivalent compared to median value on this day for the 1981-2010 period.

This provisional data is provided by the Natural Resources Conversation Service, and is subject to revision. Null percentages mean there is no measurable snowpack on that day.

Current Truckee River Flow

A key location where Truckee River flows are measured (in cubic feet per second or cfs) is near the California-Nevada state line, at the USGS Farad gaging station. This is the gaging station where required rates of flow are measured.

From March through September the required rate of flow is set for 500 cfs, and between October and February required rate of flow is 400 cfs. Flow rates are managed by the Federal Water Master and all data is provided by the United States Geological Survey.

For responsible recreational enthusiasts who monitor these flows, this map outlines all access points, features, diversions and portage options along the Truckee River from Truckee, CA to Tracy, NV.

Upstream Water Storage

Volume of water is measured in Acre Feet (AF). While many stakeholders also store water upstream, information shown here only reflects the upstream reserves held by Truckee Meadows Water Authority.

Water stored by TMWA is updated daily:

Boca Reservoir13,479 Acre Feet
Donner Lake*2,926 Acre Feet
Independence Lake*12,555 Acre Feet
Prosser Reservoir0 Acre Feet
Stampede Reservoir9,440 Acre Feet
Lake Tahoe5,649 Acre Feet

*TMWA owns 100% of the storage at both Donner and Independence Lakes.

Current Lake Tahoe Level

The Dam at Tahoe City controls the amount of water released into the Truckee River. It can retain 6.1 feet of Lake Tahoe, or at maximum 744,600 acre feet of water. This maximum volume is met when water behind the dam reaches an elevation of 6229.10 feet.

Water Treatment Plant Production

Water from the Truckee Meadows is treated at two locations: the Chalk Bluff Treatment Plant in northwest Reno and the Glendale Water Treatment Plant in Sparks. Treatment plant output varies by season, as peak summertime customer demand can be as much as 4 times typical wintertime customer demand.

Many residents in the region are also served by groundwater wells.

Hydroelectric Production

The Truckee River is an excellent source of hydroelectric power. In fact, Fleish, Verdi and Washoe hydroelectric power plants produce an average of 50,000 kWh per year. This clean energy offsets the operational power costs for Truckee Meadows Water Authority and is a key contributing factor for keeping water rates as low as possible for customers. Benefits to the environment are sizable as well. Every day that the hydroelectric plants run at full capacity, over 90,500 pounds of CO2 emissions are effectively eliminated from our atmosphere.
