  4. USGS & Civil Defense Rainfall Data Collection Network • 17 Basins • Over 120 data collection stations from USGS • 34 data collection stations from CD • Five types of measurements • Rainfall • River discharge • River level • Lake level • Lake discharge

  5. La Plata Basin Stations Sensors 14 Rainfall sensors (RF1-RF14) 4 River level sensors (RL1-RL4 4 River discharge sensors (RD1-RD4) 2 Lake level sensors (LL1-LL2) 2 Lake discharge sensors (LD1-LD2)

  6. Types of Independent Events RF- Rainfall Report RD- River Discharge Report RL- River Level Report LL- Lake Level Report LD- Lake Discharge Report RAD- Radar Detection NWS- National Weather Service Bulletin EIC- Emergency Information Center Report IR- Information Requests OE- Other Events

  7. Types of Dependent Events for Water Company Procedures on La Plata Basin RFA- Rainfall Accumulation on a station MAJ- Majority of Stations within a range of rainfall accumulation HRD- High River Discharge HRL- High River Level HLL- High Lake Level RW- Risk Watch MR- Moderate Risk HR- High Risk EP- Event in Progress

  8. List of Independent Events RF1-RF14 (rainfall sensors report) RL1-RL4 (river level sensors reports) RD1-RD4 (river discharge sensors reports) LL1-LL2 (lake level sensors reports) LD1-LD2 (lake discharge sensors reports) RAD1 (atmospheric system with potential intense, expanded or extended rainfall) RAD2 (atmospheric system with potential intense, expanded or extended rainfall has started) RAD3 (atmospheric system with intense, expanded or extended rainfall is in progress)

  9. List of Independent Events (Cont.) NWS1 (rainfall watch) NWS2 (flash flood watch) NWS3 (rainfall warning) NWS4 (flash flood warning) NWS5 (rainfall in progress) EIC1 (atmospheric system with significant rainfall has been visually detected) EIC2 (start of significant rainfall has been confirmed) EIC3 (significant rainfall in progress has been confirmed) IR1 (information request) OE1(saturated soil)

  10. List of Dependent Events RFA1- RFA14 (accumulation between .25 to .5 inches) RFA15-RF28 (accumulation of more than .5 inches) RFA29-RFA42 (accumulation between .5 to .75 inches) RFA43-RFA56 (accumulation of more than .75 inches) RFA57-RFA70 (accumulation between 2 to 3 inches) RFA71-RFA84 (accumulation of more than 3 inches) RFA85-RFA98 (accumulation between 3 to 4 inches) RFA99-RFA112 (accumulation of more than 4 inches) MAJ1 (majority of RFA1 through RFA14 take place) MAJ2 (majority of RFA29 through RFA42 take place) MAJ3 (majority of RF57 through RFA70 take place) MAJ4 (majority of RFA85 through RFA98 take place)

  11. List of Dependent Events (Cont.) HRD1-HRD4 (RD > critical value) HRL1-HRL4 (RL > critical value) HLL1-HLL2 (LL > critical value) RW (Risk Watch) MR- (Moderate Risk) HR- (High Risk) EP- (Event in Progress)
