This project determined potential water storage sites and field tested a method for improving water quality by reducing nutrient levels. Data collection during spring freshet was conducted, with flow equipment measuring water over the spillways at each of the Lakeview Irrigation District’s reservoirs. The multi-year data collection helped determine the average potential increase to storage at each location. It was noted that water diverted from Lambly Creek to the Rose Valley Reservoir accounts for approximately 50% of nutrient loading in the reservoir, which encourages algae growth. The district also field tested slow filtration through limestone, as a means to improve the water quality at the point of diversion, attempting to reduce the dissolved nutrients in the reservoir overall.
