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.
