Envision’s water right to do list
Surface water
1. How to represent Minimum Flows throughout the stream reach network a. Control Points on the mainstem (reservoir operation USACE) b. OWRD In stream Water Rights (only some reaches) c. Total Maximum Daily Load (TMDL) (relationship between discharge and temperature) 2. Contracted Water Rights stored in reservoirs (USACE) a. Priority dates? b. Points of Use?
Ground water (under development)
Stream Reach Discharge (SRD)m3/day
IDU Water Demand (m3/day)
Calculate Available ReachDischarge (ARD) m3/day.
ARD = SRD – minFlow – ISU - OSUIs ARD ≥ 0?
no yes
Consider next junior WR
Is the Use an “In Stream” Use (ISU)
Add Demand rate to “Out Stream” Use
(OSU)
Add Demand rate to ISU
yes no
Flow Model (daily time step loop)
HRUs (comprised of stream reaches)
Water Right loop ( begin with Senior WR )
Have all IDUs been considered?
Consider next IDU
Subtract Out Stream Use from Stream Reach Discharge
SRD = SRD - OSU
IDU loop ( A Place Of Use can have multiple IDUs)
no yes
Have all WR been considered
Consider next WR
no
Aggregate SRD to HRU
yes

● Each Point of Diversion is associated with a stream Reach.__ Each Point of Use intersects with one or more IDUs.
