Deal Lake Commission Wins Award For “Lake Management Success”

NALMS President Dr. Frank Browne with Princeton Hydro Co-Founder Dr. Stephen Souza accepting the “Lake Management Success Stories” award on behalf of the Deal Lake Commission.

The Deal Lake Commission’s success in the management and restoration of Deal Lake garners a prestigious award from the North American Lake Management Society

 

The North American Lake Management Society (NALMS) awarded the Deal Lake Commission (DLC) with its “2018 Lake Management Success Stories” award. The award, which was presented at the NALMS 38th International Symposium, is given annually to recognize and honor an individual or group that has made significant lake/reservoir management accomplishments.

The DLC has overseen the management and restoration of Deal Lake and its watershed since 1974. Consisting of appointees from the seven municipalities abutting the lake, the DLC’s mission is to provide leadership, guidance and resources to preserve and restore Deal Lake and its tributaries as a healthy and stable ecosystem. A true challenge in an urban environment.

“It has been both a pleasure and an honor to work with the Deal Lake Commission for the past 35 years,” said Dr. Stephen Souza, Princeton Hydro Co-Founder. “They have shown great resolve to tackle some serious problems affecting the lake and its watershed, serving as a great example for other organizations involved in the restoration of urban lakes.”

Deal Lake is New Jersey’s largest coastal lake, encompassing 162 acres. The lake is surrounded by a 4,400-acre highly urbanized watershed, with the majority of development dating back to the 1960s-1980s. As a result, stormwater management, particularly with respect to water quality and volume management can be especially challenging. The DLC has embraced the numerous challenges, and has worked diligently over the years to correct these issues.

Restored shoreline at the Asbury Park Boat Launch in Deal LakeAt the forefront, the DLC has been managing the primary cause of the lake’s eutrophication: stormwater runoff from the surrounding watershed. In 2014, with funding provided through the NJDEP’s 319(h) program, the DLC implemented a number of demonstration projects, specifically the construction of three bioretention basins, the installation of a large manufactured treatment device, the vegetative stabilization of over 500 feet of heavily eroded sections of the shoreline, and the construction of a rain garden at the Deal Lake boat launch.

Collectively these projects were shown to eliminate localized flooding, decrease floatable loading, and reduce nutrient, sediment and pathogen inputs to the lake. These and other projects implemented by the DLC over the years show that despite Deal Lake being located in a highly urbanized watershed, it is possible to implement cost-effective green infrastructure and stormwater retrofit solutions.

Deal Lake recently won another very competitive 319 (h) program for $735,000 for MTDs, tree boxes, and Green infrastructure improvements to Deal Lake, Sunset Lake and Wesley Lake.

The NALMS award nomination application, which was submitted by Dr. Souza, listed a number of additional achievements of the DLC, including:

  • Educating the community, including school children, to increase awareness and appreciation for the natural environment of the lake;
  • Sponsoring and conducting public engaged spring and fall cleanups, which annually result in the removal of 1,000s of pounds of refuse and debris from the lake;
  • Helping homeowners and public groups recognize and mindfully solve problems related to water quality, siltation, and lake restoration;
  • Serving as the liaison between lakeside communities, County agencies, and the NJDEP;
  • Microbial source tracking investigations with Monmouth University and pathogen source identification work with Clean Ocean Action to decrease E. coli loading;
  • Carp removal, invasive species management, and goose control initiatives;
  • Working with State legislators to implement stricter stormwater controls to reduce pollutant loading, increase storm resiliency, and improve recreational fishing;
  • Participating in the NALMS Secchi Dip In; and
  • Proactively suggesting and supporting community-based, practical ideas to improve the overall environmental quality of the lake and its enjoyment by boaters, anglers, hikers, residents and visitors.

Deal Lake Improves Water Quality on a Sustainable Basis

Success Spotlight: Deal Lake Watershed Protection Plan Implementation Project

Deal Lake Commission, Interlaken, New Jersey

Deal Lake is the largest of New Jersey’s coastal lakes, encompassing 155 acres and spanning over 27 miles of shoreline. The lake’s 4,400-acre watershed is highly developed, with the majority of development dating back to the 1940s-1960s. As a result, stormwater management, particularly with respect to water quality and volume management, is largely lacking.

Since 1980, the Deal Lake Commission (DLC) has served as the State-appointed steward of the lake.  Princeton Hydro secured the DLC $450,000 in 319(h) funding to implement the lake’s New Jersey Department of Environmental Protection-approved Watershed Protection Plan. The 319(h) funding was used by the DLC to conduct three projects designed to decrease stormwater-based pollutant loading, improve the lake’s water quality, and restore heavily eroded sections of the shoreline.

Asbury Park Comstock Street MTD

MTDs are very effective “retrofit” solutions that can be used to address stormwater issues even in highly developed areas. The MTD installation was complicated by site constraints including sub-surface infrastructure. Post-installation field testing and STEPL modeling conducted by Princeton Hydro confirmed that the MTD significantly decreased the pollutant loading from one of the lake’s major stormwater outfalls.

 

Colonial Terrace Golf Course Bioretention BMPs

Princeton Hydro conducted the field testing, engineering design, and permitting of three bio-infiltration basins constructed at the Colonial Terrace Golf Course (CTGC). Post-project-completion field testing showed each basin is capable of fully infiltrating the runoff generated by storms as great as 1.5 inches per hour. In addition, over 300 feet of eroded shoreline was stabilized with native plants. Doing so helped create a dense buffer that inhibits passage of Canada geese from the lake onto the golf course.

 

Asbury Park Boat Launch Shoreline Stabilization

Princeton Hydro developed a bio-engineering design for the stabilization of a badly eroded 250-foot segment section of shoreline adjacent to the Asbury Park boat launch. Coir fiber logs were used in conjunction with native plant material. As with the CTGC planting, help was provided by local volunteers and the DLC commissioners. The final element of the project involved the construction of a bioretention rain garden to control the runoff from the boat launch parking area. Signage was also installed to inform the public about the project and the benefits of shoreline naturalization.

 

The Deal Lake Watershed Protection Plan Implementation Project proved that despite Deal Lake being located in a highly urbanized watershed, it is possible to implement cost-effective green infrastructure and stormwater retrofit solutions capable of significantly decreasing pollutant loading to the lake.  These measures are part of the DLC’s continued efforts to utilize environmentally sustainable techniques to improve the lake’s water quality. This project won a North American Lake Management Society Technical Merit Award.
