Lake Okoboji covers 3,847 acres in Iowa and drops to 136 feet at its deepest point. It is a natural lake, which generally means a more stable shoreline and fewer drawdown surprises than an impoundment. Level is unusually stable, which protects dock usability and shoreline appearance year round. Short-term rental posture: Dickinson County rules. Confirm at the municipal level before underwriting rental income.

Each axis is computed by published formula from this lake's own attributes. How we score.

Water quality grade
Water A
ExcellentClear, low-nutrient water. Typically oligotrophic with high clarity and little seasonal algae.
Water B
GoodHealthy water with moderate clarity. Some seasonal variation, no persistent problems.
Water C
FairProductive water — good fishing, reduced clarity. Algae possible in late summer.
Water D
PoorNutrient-rich or heavily drawn down. Swimmable conditions vary; check before you rely on them.

Computed from measured clarity, trophic state, and drawdown magnitude — not an opinion. See the formula.

5/5

We bought in 2005 and have never regretted it. The lake is busy on holiday weekends and quiet the rest of the time. Get a dock on the main channel if you can — the coves warm up and weed over by August.
