CREATE TABLE table_204_322 (id DECIMAL, "township" TEXT, "fips" DECIMAL, "population" DECIMAL, "population\ density\ /km2  ( /sq mi ) " TEXT, "land area\ km2  ( sq mi ) " TEXT, "water area\ km2  ( sq mi ) " TEXT, "water %" TEXT, "geographic coordinates" TEXT)

what townships have the same water area as lake township ?
SELECT "township" FROM table_204_322 WHERE "township" <> 'lake' AND "water area\nkm2 (sq mi)" = (SELECT "water area\nkm2 (sq mi)" FROM table_204_322 WHERE "township" = 'lake')
