2. Test Flow Release Schedule
A pro 3osed schedule is presented below and assumes that 25cfs is the minimum discharge released
from he dam. This test plan is variable, depending on how long it takes for equilibrium at 100 cfs to be
achie ed. Allowing for 7 days of Groundwater Charge (50 cfs) and 9 days for measurements (variable
dischi irge, see below) leaves 13 days for Equilibration (100cfs) to keep the total release volume under
5000 cre-feet. Instrumentation at CR213 will need to be installed prior to the start of flow release.
Recor imended start of flow release is April 27`h assuming no weekend time off. Keep in mind that
David Varyu's earliest travel day is May 7`h. This plan assumes that all 13 Equilibration days are used
giving us an end date of May 25`h. If equilibrium is achieved sooner, then the measurements can begin
and e id sooner. If equilibrium has not been achieved within the 13 days, Tyler Artichoker will need to
decidb what to do at that time. The test release schedule is divided into 12 hour (%: day) increments.
Time =0 is approximately 7am (0700 hours) on the first day of releases, and time 0.5 is 7pm
(190C lours) on the first day. Each bar in the figure below is a 12 hour time period.

edule assumes that the saturated ground conditions will allow flow released at the dam outlet
in as surface flow by the end of each 24 hour period. In the fall under dry conditions and the low
flows from the dam, flow soaks into the ground in Upper Basin Creek and appears at the toe of
wer Basin Creek. Other concerns that could extend this flow plan are measurement issues and
erosion of rip -rap.
