, province (1994 pop. 607,000), c.1,325 sq mi (3,430 sq km), N Netherlands. Leeuwarden is the capital. The province includes several of the West Frisian Islands along the North Sea coast and borders on the IJsselmeer in the southwest.

Considerable areas have been reclaimed from the former Zuider Zee since 1930, when the reclamation of Wieringermeer (part of North Holland) was completed. The largest of the reclaimed areas is the Northeast Polder (185 sq mi/479 sq km), which with Eastern and Southern Flevoland (all reclaimed after 1937) now is part of the province of FlevolandFlevoland,
province (1994 pop. 253,700), 931 sq mi (2,412 sq km), central Netherlands, on the E shore of the Markermeer and IJsselmeer. Lelystad is the capital; other cities include Almere and Emmeloord.

 (est. 1986). Parts of the polders were flooded in World War II but have since been salvaged.

The shallow southwestern end of the IJsselmeer, now called the Markermeer, was separated from the lake by the construction of a dam and was originally intended to be reclaimed as well. The IJsselmeer and Markermeer are important freshwater fishing grounds, but silting in the Markermeer decreased water quality. Beginning in 2016, several artificial islands with wetlands were constructed in the Markermeer near the dam to improve water quality and increase wildlife habitat.

"For example, the average discharge of freshwater from the Ijsselmeer into the Waddenzee--the mud flats--is 200m3/s, so there's an estimated 200MW of potential power." An average household in the Netherlands consumes 3,500kWh of electrical power a year, so the 200MW would be enough to support 500,000 households, he says, adding: "The global potential, of course, is far bigger."
