Iowa Admin. Code r. 567-52.8 - [Rescinded]
Notes
State regulations are updated quarterly; we currently have two versions available. Below is a comparison between our most recent version and the prior quarterly release. More comparison features will be added as we have more versions to compare.
(1) Purpose. The protected flow is designed to protect and maintain adequate water supplies for ordinary household and livestock use ; for fish and wildlife use; for recreational use; for in-stream wasteload assimilation and pollution control; for beneficial water use needs in the watershed; for preservation of aesthetic values; and for other uses of a public nature.
(2) Protected flow basis. The protected flow is based in part on statistical information contained in "Low-Flow Characteristics of Iowa Streams," (INRC Bulletin No. 9 (1958)), "Low-Flow Characteristics of Iowa Streams through 1966," (INRC Bulletin No. 10 (1970)), "Annual and Seasonal Low-Flow Characteristics of Iowa Streams," (INRC Bulletin No. 13 (1976)), and "Statistical Summaries of Selected Iowa Streamflow Data Through September 1996, U.S. Geological Survey Open-File Report 98-176 (1998)."
(3) Protected flow levels.
a. At stream gaging stations. The protected flow, expressed in cubic feet per second (cfs) at points on a stream with an official U.S. Geological Survey stream flow gage are listed in the table below.
