<br />Results and Conclusions
<br />
<br />During the period of April 15 through October 31, there has been sufficient river
<br />flow at the Boating Park to meet or exceed the target flows for an average of 129 days
<br />per year, which is equivalent to 64 percent of the 200-day operational period.
<br />conclude that there is sufficient streamflow during each month of the operational period
<br />to support the flow rate amounts in the water right application.
