Summary Findings from Nitrate Levels

Water Health and Animal Life

Check out this fantastic video from Jeremy Winsor and the Fulton students as they investigate the water quality and fish health of Rainbow Lake.

As lake residents we are all concerned about our water’s health and the health of the animal life living in and off of its waters. As a man-made reservoir and lake community, RLMC monitors the lake waters on an annual basis.

Public Sector Consultants have completed a document on E. coli contamination that is available for you through the link below. Central to this effort was convening a work group to explore the issue and make recommendations for reduction. Rainbow Lakes thanks John Pohl for representing our community as a member of this work group. We are proud to say that our lakes continue test at acceptable levels of this bacteria contaminate. You can access the full report here.

RAINBOW LAKE DEPTH INFO

In recent years Rich Blemaster has spent considerable time criss-crossing the big lake.  Not fishing, he was mapping the lake bottom and its features using sophisticated sonar mapping equipment. The fruits of his efforts are now available in the form of lake bottom depth contour maps like the ones below. The full map can be added to certain fish finders made by LOWRANCE fishing electronics. (visit www.genesismaps.com to see if this is available to you.)
