Show Low Creek Watershed Enhancement Partnership (SLCWEP), in conjunction with the Little Colorado River Plateau Resource Conservation and Development Area, Inc., resulted in a systemic herbicide treatment of the lake in the summer and fall of 2011. The results were not as good as hoped, with the equally problematic coontail weed rapidly replacing the watermilfoil in the lake. Long-term efforts by the Rainbow Lake Coalition (a subcommittee of the SLCWEP) are now focused on the introduction of sterile white Amur carp, which have been proven to control excessive growth of watermilfoil for up to 10 years. Arizona Game and Fish requires mediation to ensure that the carp, a non-native fish, are prevented from escaping Rainbow Lake and potentially invading other water bodies. The Rainbow Lake Coalition is now working to design and construct a fish barrier on Walnut Creek below Lake of the Woods, which has used the carp for weed control for many years.
