Stream Nutrient Criteria Technical Advisory Committee to Meet November 25
Thursday, November 14, 2013 by Iowa DNR
DES MOINES — The Stream Nutrient Criteria Technical Advisory Committee will meet Nov. 25 to review a report in an ongoing goal to develop nutrient recommendations for streams.

The committee will meet from 9:30 a.m. to noon in the fifth floor conference room of the Wallace State Office Building, 502 E. Ninth St. in Des Moines. The meeting is open to the public.

Committee members will discuss the findings and recommendations in the Aug. 23 draft report, “Stream Nutrient Criteria Recommendations.” The report contains a review of scientific literature and technical information, and an analysis of Iowa monitoring data in an attempt to determine the role of nitrogen and phosphorus in excessive algae growth and severe oxygen fluctuations. Nutrient responses like these are harmful to aquatic organisms from the smallest mayfly nymph to the biggest smallmouth bass.  

Critiquing the findings will help committee members make recommendations that protect and allow healthy, diverse streams. Such information can be used as Iowa goes forward with the nutrient reduction strategy.

The advisory committee is charged with helping DNR protect stream aquatic life. The committee will develop recommendations that represent best‐available scientific information. If insufficient information is available, the committee will describe the deficiencies and recommend steps to resolve them.

The committee includes experts in scientific fields relating to water quality and stream ecology.
