Zebra Mussel Infestation Risk Assessment for Otter Tail County Lakes

This guide evaluates the risk of zebra mussel infestation in various lakes within Otter Tail County. Study sites include Otter Tail Lake, West Battle Lake, Big Pine Lake, Dead Lake, Middle Leaf Lake, and Poplar and Gunflint Lakes. Factors such as water chemistry, substrate suitability for attachment, connectivity to other lakes, and lake usage are assessed. Lakes like Otter Tail and Big Pine present a high risk due to favorable conditions, while lakes like Middle Leaf and Poplar show low risks. Understanding these dynamics is crucial for managing aquatic invasive species.

  1. AIS·Aquatic Invasive Species Education for Otter Tail County Risk Assessment for Lakes Where could Zebra mussels invade?

  2. Answer Guide • Study Site: Otter Tail Lake • Risk of infestation: High, likely • Why: • The water chemistry is favorable to optimal growth • It has hard substrates for zebra mussel attachment (gravel, rocks) • It is downstream from Rose Lake, which is infested already • It is connected to many other lakes • It is a heavily used lake with many lake accesses AIS·Aquatic Invasive Species Education for Otter Tail County

  3. Answer Guide • Study Site: West Battle Lake • Risk of infestation: Moderately high • Why: • The water chemistry is favorable to optimal growth • It has hard substrates for zebra mussel attachment (gravel, rocks) • It is a heavily used lake with many lake accesses • It is connected to other lakes AIS·Aquatic Invasive Species Education for Otter Tail County

  4. Answer Guide • Study Site: Big Pine Lake • Risk of infestation: High, likely • Why: • The water chemistry is favorable to optimal growth • It has hard substrates for zebra mussel attachment (gravel, rocks) • It is downstream from Rose Lake, which is infested already • It is connected to many other lakes • It is a heavily used lake with many lake accesses AIS·Aquatic Invasive Species Education for Otter Tail County

  5. Answer Guide • Study Site: Dead Lake • Risk of infestation: Moderate • Why: • The water chemistry is favorable to optimal growth • The substrate is not as suitable for attachment (softer lake bottom with lots of plants) • It is connected to many other lakes AIS·Aquatic Invasive Species Education for Otter Tail County

  6. Answer Guide • Study Site: Middle Leaf Lake • Risk of infestation: Low • Why: • The water chemistry is favorable to optimal growth • The substrate is not as suitable for attachment (softer lake bottom with lots of plants) • It is not connected to any other lakes (except East and West Leaf Lakes) • It is not a heavily used lake AIS·Aquatic Invasive Species Education for Otter Tail County

  7. Answer Guide • Study Site: Poplar and Gunflint Lakes • Risk of infestation: Low • Why: • The water chemistry is not favorable to optimal growth • They are not near any other zebra mussel infested lakes • Poplar Lake is not connected to many other lakes AIS·Aquatic Invasive Species Education for Otter Tail County
