precip	Precipitation	inches		Realtime	The measure of precipitation is important in assessing how the weather has or has not affected a particular reservoir. Rainfall amounts have a direct impact on the amount of water within a reservoir, and thus, on the amount of water available for surrounding ecosystems, as well as for public use.
elev	Elevation	ft above datum		Realtime	Elevation is the measure of the water level height in a reservoir. The assessment of elevation is useful in monitoring how changes in weather have affected the local water supply.
inflow	Inflow	cubic ft per sec		Realtime	Inflow is the measure of the amount of water flowing into a reservoir. Note that inflow is inversely calculated, in that it is obtained by subtracting the measured outflow from the change of the amount of water that is stored in the reservoir.
dv_va	Daily Averaged Streamflow	cubic ft per sec		Daily	Streamflow is a measurement of the volume of water flowing past a specific area in a river or stream. This parameter is given in cubic feet per second, and is essential to the monitoring and assessment of water resources. Obtaining averages over various time intervals helps to gain insight on how a stream is affected by wet or dry events, both in the short- and long-term. Note that such averages end on the date in question. For instance, if one wanted the 7-day average for January 7, 2006, streamflow observations from January 1st through January 7th would be used to calculate that average.
precip	Daily Precipitation	inches		Daily	The measurement of precipitation is important in assessing what weather has or has not affected a particular site. Rainfall amounts have a direct impact on streamflow, and thus, on water resources.
gh_mean	Daily Mean Gage Height	feet		Daily	Gage height represents the water level height of a particular stream or river. This parameter is solely based upon the depth of the water, and therefore does not take into account the width of the water channel for which it is measuring. Gage height is important in monitoring potential flooding, but is also significant in times of drought when water levels are low.
elev	Elevation	ft - msl		Daily	Elevation is the measure of the water level height in a reservoir. The assessment of elevation is useful in monitoring how changes in weather have affected the local water supply.
guide_curve	Guide Curve	ft - msl		Daily	The guide curve is used as a reference point for where the water levels (elevation) in a reservoir should be at different times throughout the year.
inflow	Inflow	cubic ft per sec		Daily	Inflow is the measure of the amount of water flowing into a reservoir. Note that inflow is inversely calculated, in that it is obtained by subtracting the measured outflow from the change of the amount of water that is stored in the reservoir.
outflow	Outflow	cubic ft per sec		Daily	Outflow is the measure of the amount of water that is flowing out of, or rather, released, from a reservoir.
watersupply	Water Supply	cubic ft per sec		Daily	Water supply is the amount of water that is released from a reservoir for public use.
gross_generated	Gross Generated Power	milliwatt hours		Daily	Gross generated power is the total amount of power generated by a dam.
precip	Precipitation (from 8am to 8am)	inches		Daily	The measure of precipitation is important in assessing how the weather has or has not affected a particular reservoir. Rainfall amounts have a direct impact on the amount of water within a reservoir, and thus, on the amount of water available for surrounding ecosystems, as well as for public use.
lev_va	Groundwater Level	ft below sfc		Daily	Water that resides in spaces and cracks within the earth's soil is known as groundwater. Groundwater levels are measured in terms of depth below the earth's surface. Due to the slow-moving nature of groundwater, these levels typically don't dramatically change over a given period of time. However, groundwater levels are often different from one time of year to the next.
mp	Distance Between Land Surface and Well Measuring Point	feet		Daily	The distance between the land surface and the measuring point on the well is only taken when the groundwater level has been manually measured.
