The level gauge reading at Lake Sebago on Monday, August 25, 2014 was lake elevation 264.82 feet USGS Datum. This level is 1 foot 10 inches below the spillway crest and 2.6” below the upper target limit for this date; lake level has decreased 3.8 inches from August 19, 2014. 

Woods Pond reports levels have returned to normal and sluice gates are closed, the State Park reports slightly higher than normal levels in the Songo River but the sluice gates are closed, and there are no plans to re-open through the Labor Day weekend. 

 Outflows will be reduced tomorrow afternoon August 27, 2014 to 65,000 CFM.

THURSDAY, AUGUST 21, 2014

The Westbrook Police and the Maine Warden Service notified Warren recovery operation is completed.
Outflows from Sebago will return to 85,000 cfm at approximately 15:00 today.

Please use caution and obey all warning signals and signage in the vicinity of the dams.

THURSDAY, AUGUST 21, 2014

At the Request of Westbrook Police and the Maine Warden Service the ouflow from Sebago Lake has been reduced to 40,000 CFM.

WEDNESDAY, AUGUST 20, 2014

The level gauge reading at Lake Sebago on Tuesday, August 19, 2014 was lake elevation 265.14 feet USGS Datum. This level is 1 foot 6 inches below the spillway crest and 1” above the high target range for this date. Survey work restricting flows was completed at 19:00 August 19. 

At 08:00 today the State Park will be opening one sluice gate to reduce the levels in Crystal and Long lakes and Brandy Pond until Friday evening. Also at 08:00 Warren will be increasing outflow at the Eel Weir project to 85,000 CFM with a flow breakdown of 65,000 in the Eel Weir canal and 20,000 CFM to the Presumpscot River Bypass Reach.

TUESDAY, AUGUST 19, 2014

The level gauge reading at Lake Sebago on Monday, August 18, 2014 was lake elevation 265.16 feet USGS Datum. This level is 1 foot 6 inches below the spillway crest and 1” above the high target range for this date. Yesterday, Warren reduced flows to 24,000 cfm in order to reduce water velocity in the vicinity of the Saccarappa intake structure while surveyors map the river bottom. This work has progressed well and will be completed today.  Lake outflow will be increased to 50,000 cfm at 1600 today.

Further survey work which does not require reduced velocity at the intake structure will be evaluated for completion at the end of the day today. If the work is completed today, outflows will be further increased tomorrow in order to return the lake level to mid target range.

All Recreation features at downstream projects are open.

The level gauge reading at Lake Sebago on Sunday August 17, 2014 was lake elevation 265.17 feet USGS Datum. This level is 1 foot 6 inches below the spillway crest and 1” above the high target range for this date. Today, Warren is beginning the de-mobilization phase removing scaffolding after installing five new gates to the downstream face of the Basin river gate structure. 

 Beginning this morning, and planned for four days, Warren will be conducting bathymetry studies in the Presumpscot’s Saccarappa impoundment. These studies, essentially mapping the topography of the river bottom, require Warren to maintain impoundment levels below the dam crest and are necessary for an engineering analysis to determine the feasibility for alternative methods of fish passage at Saccarappa. Later this morning, until 1700 Tuesday August 19, lake outflow will be reduced to 24,000 cfm in order to reduce water velocity in the vicinity of the intake structure while surveyors map the river bottom at that location. Once surveying at the Saccarappa impoundment is complete Warren will increase flows to bring lake level to mid target range.

All Recreation features at downstream projects are open.

THURSDAY, AUGUST 14, 2014

The level gauge reading at Lake Sebago on Wednesday August 13, 2014 was lake elevation 264.99 feet USGS Datum. This level is 1 foot 8 inches below the spillway crest and very close to the middle of the target range for this date. Currently, based instantaneous readings, the level is approximately 265.19 feet and holding steady.  Last night’s precipitation event, (6.4” Portland & 4.9” Raymond) resulted in a 2.4” rise in lake level and moved the lake level above the target range. The lower Presumpscot (as recorded just below Cumberland Mills Dam), peaked this morning at 14.7 ft at 0500, (4” below flood stage) and as of 1PM has dropped to 13.1 ft; still 9 ft above normal. 

The work installing new gates in the river bypass structure is scheduled to be completed mid week. River survey studies have been planned for the Saccarappa impoundment and tailrace areas beginning Tuesday of next week. The data gathering is anticipated to take 4 days and requires specific flow parameters to insure worker safety. 

Outflows will remain 60,000 cfm with planned reductions to accommodate survey work reviewed over the weekend to determine feasibility. 

All Recreation features at downstream projects are open.

TUESDAY, AUGUST 05, 2014

 The level gauge reading at Lake Sebago on Monday August 4, 2014 was lake elevation 265.35 feet USGS Datum. This level is 1 foot 4 inches below the spillway crest and 2.3 inches above the upper target limit for this date. Lake level has decreased 1/4 inch since Tuesday, July 29 and based on instantaneous readings and forecast precipitation is predicted to remain flat or increase at present outflows. 

Outflows will be increased today, August 5, 2014 to 60,000 cfm with 3,000 cfm allocated to the bypass reach in order to bring the lake back into LLMP target range. 

All Recreation features at downstream projects are open.

The level gauge reading at Lake Sebago on Tuesday July 29, 2014 was lake elevation 265.37 feet USGS Datum. This level is 1 foot 4 inches below the spillway crest and 1.3 inches above the upper target limit for this date. Lake level has increased 2.5 inches since Sunday, July 27 and based on instantaneous readings is still rising as a result of precipitation this week. Other impoundments reporting include Long Lake at 269.6 (8 inches above normal), Highland Lake 6.5 ft (7 inches over spillway with the sluice gate open 28 inches), Woods Pond 4.9 ft (6 inches over spillway, and Crystal Lake at 6.3 ft (sluice gate full open).  The State Park is reporting, beginning today, they will open one sluice gate into Sebago for 48 hours attempting to reduce Long Lake levels.

Outflows will be increased today, July 31, 2014 to 45,000 cfm with 3,000 cfm allocated to the bypass reach.
