Measuring points. 1.2.1. The principal radii of curvature shall be measured at three points situated as close as possible to positions at one-third, one-half and two-thirds of the distance along the arc of the reflecting surface passing through the centre of this surface and parallel to segment b, or of the arc passing through the centre of the reflecting surface which is perpendicular to it if this arc is the longer.
Measuring points. Flow and downramping compliance is measured at several locations throughout the Cedar River Watershed including: T$12119000 N 12116400 $T $T T$ $T12115900 12117600 $T 12117000 121T$17500 12116500 T 0 2 Miles 12115700T$ 12115500$T 12115000 $T USGS Gaging Station 12117600 – Cedar River below Diversion near Landsburg, Washington. Located at River Mile 20.4, this gage measures regulated stream flow downstream of Landsburg Diversion Dam. This is the measuring point for flows and downramping rates immediately below the Landsburg Diversion Dam, as required in Section B and sub-section C.2.c in the IFA. Seattle Public Utilities Diversion – Cedar River at the Diversion Dam near Landsburg, Washington. Located at River Mile 21.9, this measures the volume of water (in millions of gallons per day) diverted for municipal use and is monitored at the Landsburg Diversion Dam Facility. USGS Gaging Station 12116500 – Cedar River at Cedar Falls, Washington. Located at River Mile 33.2, immediately below the Cedar Falls Powerhouse, this gage measures regulated stream flow downstream of the Cedar Falls Powerhouse. This is the measuring point for downramping rates immediately below the Powerhouse at Cedar Falls, as required in sub-section C.2.b in the IFA. USGS Gaging Station 12116400 – Cedar River at Powerhouse at Cedar Falls, Washington. Located at River Mile 33.7, this gage is immediately upstream of the Cedar Falls Powerhouse and measures regulated stream flow downstream of Masonry Dam. This is the measuring point for flows and downramping rates immediately above the Cedar Falls Powerhouse, as required in sub- section C.1.a in the IFA. (Note: Date of installation Oct. 1, 2001). USGS Gaging Station 12115900 – Xxxxxxx Xxxxx Lake at Cedar Falls, Washington This gage located at the Overflow Dike at River Mile 37.2 and measures water surface elevation of Xxxxxxx Xxxxx Lake. This is the measuring point for determining reservoir elevation, as required in sub- sections B.7.b. (1) and B.8.c. (1). USGS Gaging Station 12115000 – Cedar River near Cedar Falls, Washington. This gage located at River Mile 43.5 and measures unregulated inflows to Xxxxxxx Xxxxx Lake. This is the measuring point for determining reservoir inflows, as required in sub-sections B.7.b. (2), B.7.b. (3), and B.8.c. (2), and serves as an index for total reservoir inflow.
Measuring points. Physical location where volumes of drinking water and wastewater will be measured, as appropriate.
