A Study of Man's Environmental Impact on Shell Creek and Sand Gulch; Conservation Workshop Presented to Donald Searcy From Gary Hassebrook August 6, 1973
Shell Creek was first described during the Major Stephen Long
expedition up the Platte River in 1819 and 1821. His expedition
crossed the creek about six miles up stream from where it enters the
Platte River and described it as being "...about eight yards across;
its bed muddy and the current moderate. Its course it circuitous, traversing...tracts of fertile and well wooded bottom land...'' The
same description would still fit today but the water has changed. Many
miles of Shell Creek are now very polluted and virtually dead.
Shell Creek begins about five miles northwest of Newman Grove and
runs about fifty stream miles before it enters the Platte River east of
Schuyler. The flow is small for the first fifteen miles until it is
replenished by Artesian wells creating a creek bed about 30 feet wide
and 1½ feet deep near its mouth.
The first fifteen miles of the creek are now dead. Mr. Mal Sutherland,
Conservationist with t he United Stated Department of Agriculture in
Columbus, reports that he used to trap beaver and other fur bearing
animals along Shell Creek in the Lindsay area but now those animals are gone apparently driven away by the polluted water. On June 15 and 16, 1972, Mr. Alan Carson and Mr . Lee Rupp of Nebraska's Fish and Game Commission took stream survey samples at various spots along the creek. At a spot 2 1/2 miles south and 2 miles east of Lindsay, they found the water
to be very green and odorous and containing only one specie of fish,
thirty-three very tolerant fathead minnows. Farmers along the creek
report that cattle will not drink the water unless it is absolutely
necessary.
The first investigation of the source of the pollution began
when a complaint was received by the Department of Environmental
Control (DEC) concerning the red color of Shell Creek. The results of
this investigation are taken from letters to Mayor Kenneth Hansen of
Newman Grove from Mr. Ronald Benson and Mr. Richard Walsh, both of the Water Pollution Central Division of the DEC and from sewage and stream sample charts.
On June 8, 1972, Mr. Walsh, Mr. Carson, and Mr. Rupp met in
Newman Grove to determine the source of the red color. The suspected cause ot the discoloration was a chemical put into the lagoon about six days earlier to remove roots from the lines. Further investigation showed that the lagoons appeared to be severly overloaded, discolored, and quite odorous. Large patches of grease globules mixed with dead algae were present in the corners of the lagoons. A slough to the south of the lagoons contained water that was gray and turgid and choked with grease. This type of material was being discharged into Shell Creek.
Mr . Carson and Mr. Rupp made a series of oxygen tests to determine
the amount of dissolved oxygen in the creek. Above the lagoons a normal reading of 8 ppm (Parts per million) was observed but below the lagoons the reading was less than 1 ppm of oxygen content. This low reading continued until the last test site at Lindsay.
We hold lots of environmental & conservation work, mostly 1970s. This 1973 paper declares Shell Creek dead. Full txt: openspaces.unk.edu/spec-coll/50/
