In a bowl, combine pears, water, lemon juice, 1/4 cup sugar, 2 tablespoons flour and 1/2 teaspoon cinnamon. Toss to mix. Spread in an 8"x8" baking pan sprayed with non-stick vegetable spray. In a separate bowl, cut together butter, brown sugar and remaining sugar, flour and cinnamon until crumbly. Sprinkle over pear mixture. Bake at 350 degrees for 45 minutes, or until pears are tender.
