Lake Level

Readings courtesy of Sue & Bill Orzell

FALL 2017 Drawdown has begun- on 10-17-17

10-17-17 Level down approximately 3/10ths of a foot (say 4 inches) below crest. Expect the lake to drop approximately a tenth of a foot per day (say 1.25 inches) ASSUMING no rain. With any amount of rain/snow melt the lake can actually rise though. We will update this page occasionally as the drawdown continues and we try to reach the 3 foot drop.

10-18-17 - Level down almost 4/10 th of a foot - approx. 5 inches.

10-20-17 at noon - Down 6/10th of a foot - ap 6+ inches below crest.

10-24-17 - Down one foot below crest.

11-10-17 - Down one and one half foot below crest. We receiced almost 6 inches of rain the preceding 2 weeks so the reservoir level came up about 4/10ths of a foot. With inputs slowing and cold weather forcast we should return to the 1/10 of a foot drop daily.

11-15-17 Down 2 feet below crest

--------------------------------------------------------------------

FALL 2016 Drawdown begun.

The state opened the gates on the morning of Monday October 17, 2016. We were 1 foot below crest at the time so we only need to get down a little more than 2 more feet. The rate of drawdown is mainly dependent on the amout of rainfall. We will update this site every few days.

10-17-16 - The lake is down 9/10 of a foot.

10-23-16 - The lake came up over a half of foot. We are now down .4 ft below crest. After a dry summer, we got some rain back. We received about 3.47 inches of rain since it started 3 days ago. The lake appears to have stopped rising though and should begin dropping after the streams slow down in a few days.

10-31-16 - Additionally since the 3 day rain storm, we received almost another inch of rain therefore the lake level is still .4 feet below crest. The state came out at 9:30 this morning and opened the gates more so the lake should start dropping assuming we don't get a lot of rain again. The forecast for the next few days looks dry.

11-2-16 The lake is down .5 feet.

11-4-16 at 5 am the lake is down .5 feet. We received another inch of rain yesterday. 

11-10-16 Lake is down 1 foot

11-16-16 Lake is down 1.5 feet. The state opened the gates some more this morning.  It is expected, barring any large rain event that we should hit the 3 foot drop level sometime during the the first week of December.

11-21-16 Lake is down 2 feet. Received some minor rain and then approx. 18 inches of snow in 2 day storm. -

12-4-16 - Lake down 2.5 feet. Almost reached this 2.5 foot drop a number of days ago but had minor warming days that melted most of the 2 foot of snow from the late November snow storm causing level to rise slightly. Most streams have slowed with the lost of the snow pack and the level is beginning to drop close to its normal rate.

 12-10-16 - We reached the 3 foot drop on Friday December 10, 2016. The gates have been closed and we should be in good shape for the winter.

1-29-17 the lake is down 2 feet below crest.

2-25-17 the lake is down 1.6 feet below crest.

3-2-17 the lake is down 1.15 feet (say 14") below crest. The ice went out today and most snow is gone. Hope for Match snow or spring rains.

3-8-17 - The gates were closed to the summer setting. The lake is still down about 13 inches. All snow pak has melted. We will need rain or a snow storm to bring the lake up. It's still early in the year though.

3-17-17- Lake is approximately 11 inches below crest. We received 18-24 inches of snow on March 14/15. Once thaw occurs we should reached crest and then some depending on the rate of melt.

3-29-17 - The Lake just reached crest.

4-7-17 - Lake is approximately .5 (half of a foot) above crest since the snow melt and almost an inch of rain earlier in the week.

Remained above crest until August 10th, 2017

8-30-17  down .1 ft, say 2-3 inches

 

2015/20016

Reached crest on February 28, 2016 after significant rain over 2 days (excess of 2 inch estimate)

 

2015 Fall Drawdown began on Wednesday, October 7, 2015. The level is APPROXIMATELY 1 foot down when it began. We will update this page as it continues.

It has been fairly dry although there is rain scheduled for the Oct. 9th and then appears to be a dry spell so expect the level to drop about 1 to 2 tenths of a foot per day (avg. 2 inches).

DRAWDOWN 2015

Gates opened Oct. 7 - level approximately 1 foot below crest.

10-22-15 Lake down 2 feet below crest

10-28-15 Lake down approximately 2.4 feet below crest 

 11-6-15 Lake down approximately 2.6 feet below crest.

11-18-15 Lake was down approximately 3.2 feet below crest. The State set the outlet gates to the winter settings. Be advised, as is the case in past years, the lake will start to rise if we get any significant amount of rain.

Hope for a short winter and we can start enjoying a full Reservoir in a few short months.

 

Fall 2014 Drawdown has begun on 9-24-14 - Level is at crest. We will monitor the level and record results here as the drawdown continues.

October 1st AM - Lake down .6 foot - about 6-7 inches

October 5th - down 1 foot.

October 14th - down 2 feet

October 15th - receieved 2.3 inches of rain

October 17th - lake down 2.25 feet

October 23rd - down 2 ft 4 inches - total 28 inches down.

October 31st - down 2.9 feet

November 4th - gates closed to winter setting - just past 3ft down.

November 18th - the lake continued to drop, extremely dry fall. Got down well past 3 ft, estimated 3.5 or so. The lake dropped 2.5 inches in 4 days so we had the state put the gates at summer setting, the lowest amount possible. The drop should stabilize or any decent amount of precipitation and the lake should begin to rise.

2013 Drawdown -

The State open the gates to begin the annual 3 ft drawdown on October 1st. We were at crest level at the time of the drawdown. Will update occasionally to monitor the drawdown. As ususal, the rate will vary with weather. With large amounts of rain the level can actually come up. Historically, if it stays relatively dry, the lake can drop about 2 inches per day.

October 1st - lake at crest.

October 4th - 4" inches below crestcto

October 16th - lake 1.1 foot below crest

October 22nd - lake 1.5 feet below crest

October 30th - lake down 2.2 feet

January 11, 2014 - Lake down.8 ft(10 inches below crest) after another snow melt

January 19, 2014 - Lake at crest or just above - a little going over spill way

Note with gate closed lake should hold or start coming up slowly depending on precipitation. Have a good winter everyone.

PLEASE NOTE - the state accidently closed the gates late last week so the draw down stopped. Emailed back and forth over the weekend. Monday morning, Nov. 4th received a call from the state at 8:30AM and found the worker that closed the gates -on his own thinking it was down 3 feet. He received a "talking to" and was heading out to re-open Monday morning, Nov. 4th. Forcast looks dry next few days so lake should begin dropping by Monday afternoon.

Due to recent flooding/rain the State delayed gate opening for approximately 2 weeks. Gates were opened on Friday, October 14, 2011 a small amount with the Reservoir 3/10 of a foot over crest. On October 18th, the gates were opened to their full drawdown setting and we were still over crest. Hopefully by this weekend (Oct 22th) we will go off of crest. Drawdown will be slower than normal this year unless we get a long spell of dry weather.
 
2010/2011 Drawdown-
 Ice went out Monday April 11, 2011. Level .25 feet above crest. Lake Crested on March 17, 2011, still ice
 The gates were closed accidently Nov. 10th or 11th. The state had a large reduction in workforce and new people are handling the drawdown. Once we informed them of the mistake, they agreed to re-open. Re-opened November 18, 2010. Gates closed 1-13-11. Lake level readings -
 March 17, 2011 - Lake crested, still ice
January 13 - 3.2 ft below crest-closed gates.
January 2 - 2.6 ft below crest- 3 days of warming melted most snow.
December 30 - 2.6 ft below crest
December 7 - 1.3 ft below crest
November 26 - .9 ft below crest
November 3 - .8 ft below crest
October 30 - .6 ft below crest
October 21 -  .3 ft below crest
October 17 - .1 ft below crest
October 14-15 received almost 2" rain
October 12 -  .2 feet below crest
 
Sept. 30th-Oct. 1st, 2010 Rain Event.
 
A large storm moved up the east coast on September 30, 2010 causing severe flooding in the area. The Tioughnioga USGS gauging station in Cortland recorded an 8 foot increase, 3 feet above the flood stage. The lake received 4.95 inches of rain in a 24 hour period. The level was .2 feet below crest at the start of the storm. Following the storm, the level was .7 feet above crest., 9/10 of a foot increase.
 
Obviously with the downstream area being flooded, the state will delay opening the gates for the drawdown. Was told on October 4th they will attempt to open the next rain free day which is expected to be October 7th. The drawdown is starting from a full lake and with the ground completely saturated, it will take extra time to get it down 3 feet. Hope for a fairly dry fall.
