Lake level forecast for March 2018 projecting a two foot drop

February 21st, 2018 Posted by Full Lake 0 comments on “Lake level forecast for March 2018 projecting a two foot drop”

The lake has risen significantly over the past several weeks with rainfall in the right places for increasing inflows into Lake Lanier. In light of that, we have had a few members express surprise about the current lake level forecast for the next month. We thought we would post some information related to that issue.

Normal Corps ACF operations call for an increase in downstream discharges beginning on March 1, given current conditions in the ACF. That and expectations for the Southeast U.S. to return to drier-than-normal conditions are what combine in the Corps’ forecast for Lanier to drop by about two feet in the next month. Here’s the scoop:

Lake Lanier rose three feet in a week from 2/8-2/15, and is now 3.4 feet higher than it was a mere two weeks ago. We caught a big break last week with heavy rain in the upper ACF basin, especially in the headwater areas of the Chattahoochee and Chestatee Rivers. The Hooch peaked at over 6,000 cfs near Cornelia on the 11th and 12th, and the Chestatee peaked at over 5,000 near Dahlonega. Lanier’s inflows from the two rivers are currently running a little over 1,600 cfs, slightly above the 59-year mean for this day of the year.

Seven-day average ACF basin inflows are currently at 30,000 cfs and were over 40,000 from 2/11 through 2/18. ACF Conservation Storage is currently above the guide curve, meaning that cumulative reservoir levels are slightly above full winter pool. In particular, Lake Lanier is more than six inches above its full winter pool of 1070 MSL. The Corps’ ACF Water Control Manual calls for releases of any basin inflow above 5,000 cfs through the end of February. On March 1, basin inflows available for storage (i.e., water that can be kept in the reservoirs) will drop from everything over 5,000 cfs to 50% of inflows over 16,000. So, in order to accommodate threatened and endangered species such as the Gulf sturgeon, whose spawning period begins around April 1, spring flows will increase across the GA/FL starting next week.

The bottom line, as always, is that it takes normal spring rains throughout the basin to keep ACF lakes full into the coming recreation season.

CALL TO ACTION: EPD Drought Response Needs to Consider Lake Lanier Water Level

August 6th, 2017 Posted by Full Lake 0 comments on “CALL TO ACTION: EPD Drought Response Needs to Consider Lake Lanier Water Level”

Member call to action! Please contact our state Environmental Protection Division and urge them to keep the Level 2 Drought Response in place until Lake Lanier gets closer to its full pool! The EPD is considering lifting the Level 2 Drought Response currently in place since Metro Atlanta is no longer officially in a drought. The problem with this approach is that it doesn’t consider that residual drought impacts on Lake Lanier can continue for long after the official drought is over since it can take some time for Lake Lanier to regain its full pool water level. Below is the press release the Lake Lanier Association has sent to media outlets. Members – the EPD needs to hear from you! Use your own words and either email or call the EPD at askepd@gaepd.org or 404-657-5947. Time is of the essence since they will be making a decision soon.

FOR IMMEDIATE RELEASE

Georgia EPD Presses For Metro Atlanta Water Conservation To Combat Drought

May 3rd, 2017 Posted by Full Lake 0 comments on “Georgia EPD Presses For Metro Atlanta Water Conservation To Combat Drought”

May 2, 2017

Faced with a stubborn drought and the warmest April on record in Atlanta, the Georgia Environmental Protection Division (EPD) is urging metro Atlantans to conserve water and follow the state’s outdoor water use schedules.

“With Lake Lanier showing only slight improvement after recent rainfall it’s more important than ever for citizens to be good stewards of our water supply,” said EPD Director Richard Dunn. “The lake remains eight feet below its full water level. Coupled with the fact that it is not unusual during a drought for Lanier to drop six feet or more over the summer, it is critical that metro Atlantans follow a Level 2 Drought Response, which allows reasonable outdoor water use while still saving water.”

During a Level 2 Drought Response, outdoor landscape watering is allowed up to two days a week, determined by odd and even-numbered addresses. Even-numbered addresses and properties without numbered addresses may water on Wednesday and Saturday before 10 a.m. and after 4 p.m. Odd-numbered addresses may water Thursday and Sunday before 10 a.m. and after 4 p.m.

The Level 2 Drought Response has been in place since November in the following 12 counties: Cobb, Coweta, Dekalb, Douglas, Forsyth, Fulton, Gwinnett, Habersham, Hall, Lumpkin, Paulding and White counties. These are counties that depend on Lake Lanier and the Chattahoochee River for water supply.

“Lake Lanier is a large reservoir fed by relatively small streams,” added EPD Director Dunn. “Recent rains have provided short-term relief for your landscape, but not enough rainfall to provide significant improvement to Lake Lanier.”

Prohibited outdoor water uses under a Level 2 Drought Response include:

  • Washing hard surfaces such as streets and sidewalks.
  • Water for ornamental purposes, such as fountains.
  • The use of fire hydrants, except for firefighting and public safety.
  • Non-commercial washing of vehicles.
  • Non-commercial pressure washing.
  • Fundraising car washes.

The following activities are allowed under a Level 2 Drought Response:

  • Irrigation of new and replanted plant, seed, or turf may be done at any time of day for 30 days after installation.
  • Irrigation of personal food gardens may be done at any time of day.
  • Drip irrigation or irrigation using soaker hoses may be done at any time of day and hand-watering with a hose with automatic cutoff or handheld container may be done at any time of day.
  • General landscape watering may be done after 4 p.m. and before 10 a.m. on the designated days.

EPD closely monitors a number of drought indicators including streamflows, reservoir levels, groundwater, short-term climate predictions and water supply conditions. Should conditions deteriorate further, a Level 3 Drought Response would have to be considered. A Level 3 Drought Response prohibits most types of outdoor water use, including general landscape watering.

Lake Lanier Association Urges Action in Response to Special Master’s Report

February 21st, 2017 Posted by Full Lake 0 comments on “Lake Lanier Association Urges Action in Response to Special Master’s Report”

Gainesville – the Lake Lanier Association released today their first public statement after the release of the U.S. Supreme Court Special Master’s report related to the Florida v. Georgia Water Wars litigation. The statement is as follows:

Through the efforts of Governor Deal and the state’s legal team, Georgia took a major step toward victory in Florida’s lawsuit against Georgia for equitable apportionment of the waters of the Apalachicola-Chattahoochee-Flint (ACF) Rivers watershed. (more…)

Why are Lake Levels not Rising?

February 20th, 2017 Posted by Full Lake 0 comments on “Why are Lake Levels not Rising?”

We have had several members asking questions about lake levels. We thought a group communication might be helpful at this point.

It’s been raining, right? So why isn’t Lanier’s water level going up?
As this is being written, Lanier is at essentially the same level as it was in December and January, and about a foot below the same date in November. But it’s rained about five inches (about average) around Lanier since the beginning of the year and the average discharges from Buford Dam are the lowest they’ve been since late 2014. (more…)
