South Nevada Water Authority is using LakeWatch software to provide quantitative results on the water quality of Lake Mead…

INDUSTRY: Water Supply

PRACTICE: The Southern Nevada Water Authority (SNWA) provides a water system for pumping, treating and delivering Colorado River water from Lake Mead to the Las Vegas area.

They are committed to managing the region’s water resources and developing solutions that will ensure adequate future water supplies for the Las Vegas Valley.

CHALLENGE: SNWA comprises of representatives from each of its member agencies: Boulder City, Henderson, Las Vegas, North Las Vegas, Big Bend Water District, Clark County Sanitation District and Las Vegas Valley Water District.

In order to make collective decisions regarding the health of the lake, it is important that they are supplied with the same quantitative information regarding the level of nutrients and dissolved salts within Lake Mead.

Prior to the introduction of LakeWatch software, the Las Vegas Water Wash (LVWW) committee had been tasked with the job of analyzing and trending water quality data. This was a huge job owing to the amount of data collected from the lake and reports were difficult to produce in a timely manner.

SOLUTION: Using LakeWatch, consultants were able to determine a trophic level rating for the lake and correctly analyze trends in individual variables.

LakeWatch software is now employed on a permanent basis to help store, analyze and determine the trophic level of the lake. This means large volumes of water quality data are being put to good use and of benefit to decision makers.

BENEFITS: All the members of the SNWA have access to the same quantitative reports on water quality, which helps in making collective decisions.

ENVIRONMENT: LakeWatch software version 2.0 (backend is a MS Access database).

SUMMARY: The client is completely satisfied with the level of analysis that LakeWatch is now providing and an enthusiastic promoter of the product. We have recently modified the program based on some of the early recommendations from the SNWA and the base product now incorporates these changes.
