Analysis Of The Water-Quality Standards Proposed By The Nevada Division Of Environmental Protection, City Of Las Vegas, Nevada
Analysis Of The Water-Quality Standards Proposed By The Nevada Division Of Environmental Protection, City Of Las Vegas, Nevada
Publications (WR)
The Nevada Division of Environmental Protection (DEP) has proposed water-quality standards, applicable to Las Vegas Bay and Lake Mead, for (1) chlorophyll, (2) un-ionized ammonia, and (3) pH.
We have concluded that the proposed standards are unlikely to protect or improve water quality in Lake Mead. The proposed chlorophyll standard:
May harm the fishery. Lakes with more chlorophyll have greater fish production.
Will not improve clarity. Chlorophyll concentrations above 30 ug/1 have little effect on clarity.
Will not protect against scums or dominance by blue-green algae. Lake Mead shows no consistent relationship between chlorophyll and scums or blue-green dominance.
Will …

Ninety-three wildlife agencies were surveyed for information on their attempts to improve fish habitat. In addition, an annotated bibliography including over 100 summaries was completed on:
1. largemouth bass cover requirements and preferences,
2. use and effectiveness of artificial cover,
3. aquatic plant introduction and species requirements for germination and establishment,
4. terrestrial plant introduction and species requirements for germination and establishment, and
5. nutrient exchange between sediment, aquatic plants, and water.
A reconnaissance of existing terrestrial and aquatic vegetation was completed in June 1986 including the production of a video tape of the Nevada shoreline of Lake Mead.
