The tapes can be purchased or constructed.įor tips see the OSU online publication Measuring Well Water Depth. This equipment typically consists of two wires with an electronic sensor that indicates when, and at what depth, the tape has hit water. This is the easiest, and most common method to measure your well's static water level. The water level after pumping has stopped, but before the well has fully returned to the static water level. The level of water in an observation borehole will be a composite of all aquifers that are penetrated by the borehole. This drawdown always exceeds the drawdown in the surrounding aquifer. Pumping causes the formation of a cone of depression. The water level in the well during drawdown. The water level in the aquifer from which you are pumping, measured after the well has rested for several hours (so as not to measure the pumping or recovering water level). Pumping and recovering water levels do not reflect the water level of the surrounding aquifer, and should not be used as indicators of whether a well is going dry. Measure the static water level, rather than the pumping or recovering water level by letting your well rest for several hours before measuring. forms that detail a wells depth, construction, and. Make sure to use approved sanitary procedures to prevent bacteria or other surface contaminants from entering the system. Water Level Meter (or E-Line): A tape-like meter used to measure water levels in a well. If you are interested in taking your own water depth measurements: HS-SFCC Portable Ultrasonic Water Depth Gauge It has perfect water depth measurement function. The device can caculate current water depth. Place ultrasonic transducer on water surface or into a certain position into water. The location of these wells, along with long-term trends in water levels are available here. Water Depth Gauge is a necessary instrument to measure water depth in reservoir, lake, river, shallow sear. These wells are monitored frequently and provide valuable information for people living in the surrounding area on seasonal fluctuations and long-term trends. The Oregon Water Resources Department manages a number of observation wells throughout Oregon. You don't need to measure your own well to obtain information about groundwater levels in your area. It takes 4 to 6 measurements per year over a period of at least 5 years to obtain useful data on water level trends. Groundwater and Surface Water Interactions.
