<br />of plant nutrients from various sources (discharges of wastes,
<br />urban runoff, drainage from agricultural lands), and (2) canalizing
<br />rivers. When one examines the remedial approaches now available,
<br />they fall into four areas: chemical, biological, mechanical, and
<br />ecological control. Ecological control, designed to make the
<br />environment less productive, is the remedial approach of choice.
<br />Knowledge to permit application of some remedial approaches is
<br />now available, but new knowledge to be generated through research
<br />is needed to more effectively: (1) slow down nutrient input;
<br />(2) make nutrients already present unavailable; (3) remove nutrients
<br />in the form of plant crops, such as waterweeds and bottom sediments;
<br />(4) interfere with sediment-water interchange; (5) modify appropriate
<br />physical aspects of the environment; and (6) create and stimulate
<br />destructive algal diseases. In the National Eutrophication Research
<br />Program, research in these areas is underway or planned.

<br />Business Meeting
<br />
<br />Mr. Conaway, Secretary of the Committee, announced that the l53rd
<br />meeting of the Committee would be held at Jackson Lake Lodge, Grand
<br />Teton National Park, on June 26, 27, and 28.
<br />
<br />Mr. Grindberg moved that a resolution contained in Governor Guy's
<br />banquet address be approved by the Committee. Mr. Summers of
<br />Missouri seconded the motion.
<br />
<br />The resolution pertained to the problem of bank stabilization
<br />below Garrison Dam in North Dakota. The resolution asked MBIAC
<br />to urge the Congress to direct and authorize the United States
<br />Army Corps of Engineers to construct, at Federal expense, the
<br />operation and maintenance of any additional structures needed
<br />to stabilize the banks of the Missouri below Garrison Dam.
<br />
<br />After considerable discussion, it waS agreed that action on the
<br />motion should be deferred until the next meeting of the Committee
<br />and the Chairman was directed to request clarification from the
<br />Water Resources Council as to the Committee's authority in matters
<br />of this kind.
