The Owl Rain Gauge Garden Stake is a great decorative rain gauge providing both form and function. The glass rain gauge vial (udometer) is easy to read and measures up to 7 inches of rainfall. The rain gauge vial / tube is designed with a flat bottom, providing more accurate rainfall measurements. This rain gauge features a study metal stake with a classic antique bronzed finish and a whimsical garden owl design. The metal stake twists apart making it easy to store during the winter. The glass rain gauge vial (udometer) makes this stake a wonderful decorative garden item, however be sure to bring the glass vial indoors when temperatures drop below freezing, when water turns to ice it expands causing the vial to break.
