(a) Subsequent to the approval by the Commissioner of the information filed under Section 26-141a-5, the operator of any impoundment or diversion subject to these regulations shall cause a release on each day of the current month a daily flow not less than that computed by multiplying the drainage area by the appropriate flow obtained from the following table:

For impoundments—percent chance of occurrence of corrected calendar month water surface elevations being equal to, or lower than, the elevation on the first day of the current month.

For diversions—percent chance of occurrence of previous calendar month flow being equal to, or lower than, the actual flow during the previous month.

(b) Except that flow rates equal to, or exceeding, the mean inflow rate for March shall be allowed to pass during any consecutive five (5) days from February 15 to March 15. If the required Daily Average Release is below 0.20 cubic feet per second per square mile of drainage area, the number of days of such release of March mean inflow shall be reduced in accordance with the following table:

Required Daily Average Release	Required Number of Days of Release of March Mean Inflow
0.15	4
0.10	3
0.05	2
0.01	1

(c) The required daily releases shall be at a constant instantaneous rate throughout the day unless a variance is granted under Section 26-141a-4.

(d) The releases required by this section shall be determined in the watercourse immediately below the impoundment or diversion, or in the case of existing impoundments or diversions, in the locations where releases normally occur.

(e) All impoundments or diversions placed in operation subsequent to the effective date of these regulations shall include discharge devices with adequate controls to provide the required releases.

(f) :Except for flows required by (b), no release shall be required which is in excess of the natural flow of water into the impoundment or diversion on that day.

(g) If the impoundment or diversion is downstream of an impoundment or diversion which is in noncompliance with these regulations, the required releases may be reduced to the extent of the upstream noncompliance.

(h) Releases shall not be made through discharge devices which the Commissioner has found will discharge water of unsatisfactory quality for the preservation, protection or safe maintenance of the natural or stocked wildlife.

(Effective April 24, 1979)
