2018 Aquatic Plant Guide
The Borough of Mountain Lakes The Aquatic Plants of Mountain Lakes Created March 2017 Borough of Introduction to Aquatic Plants Mountain Lakes 400 Boulevard Aquatic plants in a lake come in many different sizes, shapes and Mountain Lakes, NJ function. This diversity is similar to the different components of a 07046 forest, having low grasses, understory shrubs, diminutive trees and vines, and canopy forming trees. Different aquatic plants inhabit dif- 973-334-3131 ferent ecological niches depending on a myriad of physical, chemical http://mtnlakes.org and biological conditions. Although many lake recreational users view aquatic plants as nui- sance “weeds”, a balanced native aquatic plant community has sev- eral important ecological functions. These include: Shoreline Buffer Sediment Stabilization Wildlife Habitat Aesthetics In this guide: Nutrient Uptake Red indicates an Aquatic plants fall into the following broad categories.

Pickerel Lake Aquatic Plants
Lake Conservation Notes Northeast Glacial Lakes Watershed Project 600 East Highway 12, Suite 1 Webster, SD 57274 Phone: 605/345-4661 Common Aquatic Plants of Pickerel Lake Aquatic macrophytes (macro = large, phytes = plants) are an essential component of a lakes ecosystem. They provide habitat for aquatic insects and fish, food for invertebrates and wa- terfowl, produce oxygen (essential for all aquatic life), and are an important component of a lakes nutrient cycle. Aquatic plants are classified by how and where they grow. Emergent aquatic plants grow in shallow areas where they are rooted in the water, however a majority of the plant is exposed above the water’s surface. Examples of emergent plants are cattails and bulrush. Floating-leaf plants are rooted in the bottom, have long stems and large leaves that float on the water’s surface. Floating-leaf plants include pond lilies and the large-leaved po- tamogetons. Submersed aquatic plants are found living completely under the water. Examples include coontail and sago pondweed. The following species were found during a survey of Pickerel Lake, August 2020. Coontail (Ceratophyllum demersum) Coontail continued: Native. The most abundant aquatic plant occurring in Pickerel Lake. Coontail is a submersed plant that can survive in low light allowing the plant to grow in the deeper areas of a lake. Un-rooted plants tend to drift around the lake in large mats of vegetation. The plant has long stems with whorled spiny thin leaves surround- ing the stem. The leaf whorls become quit dense at the end of the branches. Can grow to nuisance levels in lakes with high levels of phosphorus. -

Deep Creek Lake Submerged Aquatic Vegetation Survey 2015
Resource Assessment Service Deep Creek Lake Submerged Aquatic Vegetation Survey 2015 Report of Survey Activity and Results Prepared For Maryland Department of Natural Resources Maryland Park Service Prepared by Julie Bortz and J. Brooke Landry Maryland Department of Natural Resources Table of Contents Executive Summary……………..……………………………………………….……………. 1 Introduction………………………………………………………………….………………… 3 Methods Field………………………………………………………………….…………………. 4 Analysis…...…………………………………………….……………………………… 6 Results………………………………………………………………………………………….. 8 Discussion and Conclusions...……………………………………………………………….. 18 Recommendations…...………………………………………………………………………...25 References……………………………………………………………………...………………27 Appendix A Appendix B Appendix C Appendix D Appendix E Appendix F EXECUTIVE SUMMARY Submerged aquatic vegetation, or SAV, can be found in a variety of aquatic habitats and forms the foundation of healthy lake ecosystems. Similar to their terrestrial counterparts, SAV are underwater grasses which provide a myr- iad of important ecological functions. Through the process of photosynthesis, SAV produce oxygen which is vital to the survival of all lake organisms. It provides food, habitat and nursery grounds for many species of fish and invertebrates, absorbs nutrients which decreases the likelihood of algal blooms, improves water clarity by reducing turbidity, diminishes shoreline erosion by reducing the effects of waves and currents, and is a major food source for waterfowl. Healthy native aquatic plant communities also help prevent the establishment of invasive plants like Myriophyllum spicatum (Eurasian watermilfoil) and Hydrilla verticillata (Water thyme). During the summer 2015 field season, Maryland Department of Natural Resources (DNR) Resource Assessment Service (RAS) biologists conducted a 6th year of SAV monitoring in Deep Creek Lake (DCL). Despite its inherent ecological benefits, SAV can be an impediment to recreation and boat traffic in shallow areas, or in areas with fluc- tuating water levels. -

Aquatic Vegetation Survey
Page 1 of 22 2020 Point Intercept/Navico Bio Base Survey Lake Washington, LeSueur County, Minnesota Aquatic Vegetation Survey Submitted by: www.clarke.com Submitted to: Lake Washington Improvement Association July 20, 2020 Page 2 of 22 Summary An aquatic vegetation survey of Lake Washington (DOW 02008400), located near Kasota, MN in LeSueur County, was conducted on July 8th and 9th. The Navico Bio Base System was used at the same time to also electronically determine vegetation densities and is available for the Lake Washington Improvement Assoication to use as a base line survey. A total of nine native and one non-native plant species were identified. Plants were found to a depth of twelve feet, but most were restricted to depths at eight feet and shallower. Native plant species found included: Muskgrass (Chara sp.), Coontail (Ceratophyllum demersum), Flat Stem Pondweed (Potamogeton zosteriformis), Clasping Leaf Pondweed (Potamogeton perfoliatus), Elodea (Elodea candensis) Large Leaf Pondweed (Potamogeton amplifolius), Water Celery (Eelgrass) (Vallisneria americana), Water Star Grass (Heteranthera dubia) and White Waterlilly (Nymphaea odorata). Non-native plant species found included: Curly Leaf Pondweed (Potamogeton crispus). Curly Leaf Pondweed was found at 10 points throughout the lake. Curly Leaf Pondweed was found at an average depth of five feet and at a max depth of seven feet, intermingled amongst native species. Other Notes The surveyors noted very high surface water temps ranging from 85 degrees to above 90 degrees in shallow water and bays. Overall surveyors saw planktonic algae grow throughout the lake causing water clarity to be very low with only 1 or 2 feet of clarity. -

Potamogetonaceae Pondweed Family
Potamogetonaceae pondweed family Only two genera form the pondweeds, numbering about 90 species worldwide. All have perfect flowers arranged in a spike or head. Perianth is absent; flowers are four-merous. Some species exhibit Page | 1421 heterophyllous leaves. An important character is the presence or absence of lacunae, rows of colourless cells on either side of the central axis. All perennial, they are an important food source for waterfowl. (Haynes and Hellquist, 1996, 2000) Stipular sheaths of submersed leaves free from base of leaf blade, or adnate <½ Potamogeton length of stipule; leaves both submersed and floating or all submersed, submersed blades translucent, not channelled, flattened; peduncle stiff, if long enough then projecting inflorescence above surface of water. Stipular sheaths of submersed leaves adnate to base of leaf blade for 2/3 or more Stuckenia length of stipule; leaves all submersed, blades opaque, channelled, turgid; peduncle flexible, not projecting inflorescence above surface of water. Potamogeton L. pondweeds Herbaceous aquatic species, they are found in estuarine waters or fresh water. The leaves may be aerial, emergent, floating or wholly submerged. All are alternate along the rooting stems. The flower spikes are sheathed by stipules in bud, expanding upon a peduncle to the surface as they mature. Fruit is a drupe, soon becoming compressed. Hybridization is common as are sterile plants. The following key is of some field value, if material is mature. Morphological characters are often not sufficient to separate some of the more difficult species and their hybrids. Key to species A. Plants heterophyllous, floating and submerged. B B. Leaves large, submerged 4-6mm wide, >25 veins, may be Potamogeton amplifolius plicate.
