Aquatic Plant ID

They go by different names. You may call them “weeds,” “grass” or “moss.” Aquatic plants are an integral part of the Tennessee River’s ecosystem, whether providing nutrients for the species at the bottom of the food chain, cover and ambush areas for largemouth bass or food source for the multitude of local waterfowl.

This guide provides information to help you understand when these plants are most productive, where they grow and—most importantly—help you identify them. Whether you are an angler, property owner or any other lake user, we invite you to learn more about the aquatic plants present in our Tennessee Valley region reservoirs.

The guide also offers season-by-season tips for fishing among these plants.

Floating and Floating Leaf Plants

Muskgrass

Native muskgrass (Chara sp.) can be finicky in growth cycles, seeing boom and bust years. When in a “boom” year, muskgrass will likely be one of the first species to begin growing.

Muskgrass

Description

Muskgrass is a green macroalga up to 3 feet tall and anchored to the bottom by rhizoids. It has no true leaves or flowers. Six to eight even-length, cylindrical “branches” occur in whorls at nodes along the stem-like central axis. Small bead-like reproductive structures are found along the “branches” with short, bract-like projections at the base. Muskgrass may have a rough appearance and a gritty feel and skunk-like odor.

Habitat

Muskgrass is a common native species usually found in shallow, quiet water with high levels of calcium carbonate. Dense growth sometimes interferes with boating and fishing, but muskgrass is an excellent food for waterfowl. It occurs throughout the Tennessee Valley region.

Identifying Features

What It Looks Like—Muskgrass has a rough or crunchy feel. As it gets its name, the plant is easily identified by its foul odor, often said to smell like garlic or onion.

Max Depth—6 feet

Where to Find It—Muskgrass can be found in a variety of places. This plant dominates in areas where invasives like hydrilla and milfoil aren’t present. Look in shallow, calm water areas.

Similar Species—Muskgrass can resemble coontail; however, the foul odor of muskgrass is often a giveaway.

Seasonal Fishing Techniques

Spring—Muskgrass experiences “boom” and “bust” growth cycles. In a “boom” year, it will likely be one of the first species to begin growing. Try a rattle-trap, big swim bait or Carolina rig through this brittle charophyte.

Summer—Unlike other submersed aquatic plants, muskgrass may not top out during the summer months. Muskgrass can be easily fished with swimbaits and other weedless presentations.

Fall—Competition for space with invasives will often leave muskgrass confined to shallow depths and areas void of other species. Look for muskgrass patches among other species and fish them while other plants are still actively growing and hard to fish.

Winter—Muskgrass will often die completely back so no need in targeting this species during winter.

Drawbacks

Muskgrass can impact water use in some areas.
