I thought the following
information would be good to share with you in the midst of the drought
and the continuing concern about the low lake level. The research was
done to try to put into perspective what the future of Eagle Mountain
Lake will be. There was an article in the Star-Telegram recently about
water conservation. Click here for the Star-Telegram.com article.
Mountain Lake Level Information And Future
The lake has been holding at 10.5 feet for a while thanks to the East
Texas water pipeline that is connected to the lake. Below is a study of
our lake put together to help explain what is happening and what the
42 of the last 75 years the water level varied from the full level
(649.1) no more than +2 feet high and no less than 5 feet low which is a
normal condition. The outlying years of low and high water levels are
1940 -8 feet
1941 +7 to –6 feet
1942 +10.5 to -10.5 feet
1943 -11.5 feet
1952 -8 feet
1953 -12 feet
1954 -10 feet
1955 -12 feet
1956 -20 feet
1957 -19 to +10 feet
1958 +4.5 feet
1959 +4.5 feet
1962 +3.5 feet
1966 +3.5 feet
1974 +3.5 feet
1980 -9.5 feet
1981 -10.5 to +6 feet
1982 +3 feet
1983 -7 feet
1984 -9.5 feet
1989 +3.5 feet
1990 +8 feet
2000 -10.5 feet
2001 -8 feet
1992, the Eagle Mountain Water Treatment Plant was constructed. Each year
the City of Fort Worth takes out around 6 feet of water from the lake.
About 5 feet of lake water evaporates and about 6 feet of water is released
in to Lake Worth, which feeds water to the Holly Water Treatment Plan and
Lockheed-Martin cooling. In the past this would be replenished by
rainwater, runoff, and water released from Lake Bridgeport. Typically, 9
feet of water from Bridgeport is released and 6 to 30 feet of rainwater
is collected into the lake.
In 2013, the lake only received 2.7 feet of water from Bridgeport and 3.4
feet of rainwater. However, the pipeline from East Texas water that was
connected to our lake in 2009 was run every day in 2013 pumping a total
of 12 feet of water into the lake. The lake got to a low of only –6 feet
even in such dry conditions. From 2009 to 2012 the pipeline on the
average about 2 feet into the lake each year.
So far, in 2014 we received no water from Bridgeport and 3.7 feet of
rainwater. The pipeline has pumped a total of only 6.5 feet of water into
the lake through October because the pipeline was shut down for 68 days
early in the year for modifications. In August, the Eagle Mountain
pipeline was shut down for 37 days because all the water was used up
because of heavy demand elsewhere over Tarrant County. The Eagle Mountain
Pipeline has been running continuously since September 19th,
2014 and the Lake level has stabilized at -10.5 feet low.
Some bad news is that in January 2015 the pipeline will shut down for 6
to 8 weeks for maintenance. Without rainwater, this will probably drop
the lake level about 2 feet. Last December, January and February the lake
collected about 1 foot of rainwater and there will be no water coming
from Bridgeport. Pray for more rain this year.
On a positive note, TRWD has commenced construction of a third pipeline
from the East Texas lakes that will increase pumping capacity by 30% by
2020 and 50% by 2030. This will easily accommodate the new Tarrant County
growth needs. The El Nino cycle is underway and it is hoped that will
fill the gap until 2020. With the new pipeline, we will return to normal
lake levels for many years to come and we will remain Lake Country.

Visit with Santa
LCPOA sponsored event “Visit with Santa” was quite successful on December
6th. The pictures from this event are posted to our LCPOA website here.
hope everyone will consider joining in 2015, as these great events are
not possible without your membership. It has been a productive year for
Lake Country Property Owners Association. Look for the invite to join
LCPOA in your mailbox the beginning of January 2015.
