Pond Boss Forums AQUATIC VEGETATION Balance of plants in the environment Iris vs Pickerel

Rod, our elevation is 6500. Pond bottom is clay from decomposed Mancos shale. Surface water temps rise to mid 70s in the heat of summer. Irrigation water inflow is cool enough to keep trout alive all summer.

My biggest concern is that the roots will freeze in winter when the water level drops below where either iris or pickerel is growing.
