Ideal Power Con­vert­ers secures new fi­nanc­ing that the five-year-old com­pany says will go to­ward prod­uct devel­op­ment and growth.

Price match­ing might sound like a dream come true, but hol­i­day shop­pers should be sure to read the fine print be­fore count­ing on sav­ings.

As long as Cen­tral Tex­ans are pray­ing for more rain to re­fill their reser­voirs, they also might want to pray for less soil to flow with it.

Sed­i­men­ta­tion — a fancy word for dirt wash­ing into wa­ter­ways and set­tling on the bot­tom of riverbeds and lakes — slowly eats into the amount of water that reser­voirs can hold.

Some Texas lakes — in­clud­ing Lake Buchanan, one of the key reser­voirs for Cen­tral Texas — have lost more than 10 per­cent of their ca­pac­ity since they were built. Statewide, Texas reser­voirs have lost mil­lions of acre-feet of ca­pac­ity.

A sin­gle acre-foot of water is enough to sat­isfy the needs of three av­er­age Austin house­holds for an en­tire year.

“Ca­pac­ity is de­creas­ing over time,” said Ruben So­lis, di­rec­tor for sur­face water re­sources at the Texas Water Devel­op­ment Board.

The re­al­iza­tion isn’t new, but over the past sev­eral years new tech­nol­ogy has al­lowed devel­op­ment board an­a­lysts to put a more pre­cise reck­on­ing on just how much ca­pac­ity Texas reser­voirs have lost. Still, as Texas looks at a lot of op­tions to solve its water prob­lems, sed­i­men­ta­tion ap­pears

A boat car­ry­ing sed­i­men­ta­tion de­tec­tion equip­ment passes wa­ter­falls on Lake Buchanan. The lake has lost about 12 per­cent of its ca­pac­ity to sed­i­men­ta­tion.
