March 2018 Choptank River News


The smells of spring are quick to follow the start of March, which has our minds thinking about oysters and water quality monitoring. The launch of the new Chesapeake 10 Billion Oyster Partnership has us thinking about the Marylander’s Grow Oysters (MGO) program and all of our efforts to restore the Chesapeake’s famous bivalve. We’re also taking our water quality monitoring data to the next level with our RiverWatch platform, which allows the public to see near real-time grades for our sampling stations as we collect data throughout the sampling season. Read more about these two efforts in this month’s Choptank Newsletter.

ShoreRivers Joins the Chesapeake 10 Billion Oyster Partnership

Think of what an additional 10 billion oysters in the Chesapeake Bay would do for water clarity and the overall health of our waterways. We know that oysters are crucial to a healthy Bay and a strong economy, especially in the Choptank River, but the current population is only a tiny fraction of its historic size. ShoreRivers joins a growing number of over 30 partners across all sectors of the bay to embark on a goal to plant 10 billion more oysters by 2025.  

This partnership is a way to bring together efforts from aquaculturists, commercial fisherman, and restoration groups to focus on what really matters – putting more oysters in the water. There have always been opinions about planting oysters in sanctuaries versus planting them on commercial harvest bars, but what this partnership will do is work to make sure that oysters are being planted everywhere, and that those plantings are sustainable by using science-based management practices. This approach helps to ensure that the economy, the environment, and water quality all benefit. 

ShoreRivers has a long history of supporting the planting of more oysters in our rivers: we manage the MGO program on the Choptank, Miles, Wye and Chester Rivers which results in the planting of thousands of oyster spat; we advocate for the continued efforts to restore and maintain the oyster sanctuaries in Harris Creek, the Tred Avon River, and the Little Choptank; and we even work with school students to build oyster cages and learn about the oyster biology so one day they can grow up and become oyster experts and help to continue to protect our Bay. 

This is just the beginning. Learn more about the #10BillionOyster Partnership here and find out how you can be a part of this effort:

Improving Transparency of our Water Quality Data - RiverWatch is LIVE!

Behind the scenes our scientists and Riverkeeper have been working to make our water quality data more accessible to our communities, volunteers, partners, and decision makers. Our new merged organization has over 200 water quality monitoring sites throughout the Choptank, Miles, Wye, Chester and Sassafras rivers. The data we collect and analyze is vital to the community – it drives the work that we do and where we focus our restoration efforts; it helps scientists monitor large-scale oyster restoration projects; it supports our policy advocacy; and it’s used to protect sensitive waterways and habitats from development. We want this resource to be readily available to our community.

Working with Chesapeake Commons, a software developing company with an environmental mind-set, we were able to take water quality data that we use to generate our report cards, and make it available online in an interactive platform for users to view.  Visit to see our new RiverWatch interface. 

Monitoring sites are indicated with a symbol. A gray symbol indicates those sites where we only sample the water for physical parameters, such as temperature, salinity, pH, dissolved oxygen, and turbidity. A color-coded symbol indicates sites where we also collect nutrient samples, and the color for the nutrient sites indicates the grade for that site. Once a site is selected you’ll be able to view results for all the parameters that we collected. We encourage all of our volunteers, members and partners to use this tool as a way to monitor our water quality throughout the sampling season. As soon as we get underway with our 2018 sampling season in May, we’ll be updating the website monthly to display the most recent samples that were collected. 


February 2018 Choptank River News


If I were to tell you how energized and how quickly our team hit the ground running as the newly formed ShoreRivers, you would tell me that the Choptank River has a better chance of freezing over than accomplishing all of that! Planning the February 16th Cambridge Wild & Scenic Film Festival, kicking off the Maryland General Assembly’s legislative session, evaluating toxic pollution killing a lake owned by the Girl Scouts, assessing attitudes toward the rebound of our river’s underwater grasses, and more are all things that we dove head-first into as a the new ShoreRivers.

So, while you reflect on how beautiful the river looked when it froze over early last month, read more about all of these projects in this month’s Choptank River newsletter. I’m excited about what more we’re going to accomplish as a regional entity protecting the Choptank River and our other local waterways, and I hope you’ll join us in this mission.

MD General Assembly's Legislative Session is Off to the Races

If you remember from January’s newsletter, our Riverkeepers were in full attendance at the Environmental Summit. That night, the environmental community’s legislative agenda was released. It highlighted key lawmakers who are working to support those efforts. Our Riverkeepers and other staff are working hard to move forward those legislative actions that will improve local water quality on the Eastern Shore, and fight against those pieces of legislation that would backtrack on all the progress we’ve made to clean up our waterways. See below for a list of our legislative interests:


  • U.S. Climate Alliance – Membership (SB138/HB3)
  • Community Healthy Air Act (SB133/HB26)
  • Use of Chlorpyrifos – Prohibition (SB500/HB116)
  • Mosquito Control – Notification to Municipalities (HB400)
  • Sale or Transfer of Home With On – Site Sewage Disposal System – Nitrogen Removal Technology Requirement (HB458)
  • Expanded Polystyrene Food Service Products – Prohibition (Styrofoam Ban) (HB538)
  • Forest Conservation Act (TBD)


  • Bay Restoration Fund – Fee Exemption, Disbursements, and Financial Assistance (Septic Stewardship Act of 2018) (SB314/HB361)
  • Chesapeake Bay Bridge Crossing – Eastern Shore Local Government Consent – Repeal (SB34/HB560)


Williston Lake Watershed Assessment

Evaluating Toxic Pollution Killing a Lake Owned and Used By the Girl Scouts

In 2008, Williston Lake in Caroline County – owned and operated by the Girl Scouts –turned completely green. DNR scientists identified that the algae present was Microsystis aeruginosa, commonly known as blue-green algae. Due to the toxins in the algae, during large blooms M. aeruginosa can create a harmful algal bloom (HAB) that can kill aquatic organisms as well as pets and be harmful to human health. Because of this threat, the lake was closed from 2009-2011, devastating the Girl Scouts and the local community.

Unfortunately, efforts to treat the toxic algae using methods of barley straw and other treatments proved to be merely a Band-Aid, and did not treat the real issue of the large nutrient loads entering the lake from the surrounding watershed. Understanding that the long-term environmental sustainability of the lake and economic stability of the camp depend on clean water, the Girl Scouts requested that ShoreRivers conduct an assessment of the Williston Lake Watershed for the purpose of identifying and prioritizing opportunities to reduce pollution loads. Through a National Fish and Wildlife Foundation grant, ShoreRivers is undertaking a watershed assessment for the area that drains to the Lake. The goals of the Williston Lake Watershed Assessment and Management Plan are: (1) to identify sources and quantities of nutrients and sediment loads impacting Williston Lake and, ultimately, the Choptank River; and (2) to create a management plan with a prioritized list of actions that the Girl Scouts, farmers and other watershed partners can use as a blueprint to help reduce inputs and improve the water quality of the lake.


Changing Boater Behavior on Underwater Grasses

-by Rebecca Murphy

This past October, ShoreRivers began working with the Ocean Foundation to design a campaign focused on changing boaters’ behaviors towards submerged aquatic vegetation (SAV) in the Chesapeake Bay. Significantly, SAV represents one of the most visible ways to determine the water quality in our rivers. It provides key habitat for aquatic species such as blue crabs and striped bass, increases dissolved oxygen levels, and absorbs nutrients and sediments to improve water clarity. However, underwater grasses have been known to cause trouble for boaters on the waterway by getting stuck in and damaging propellers, particularly near the shoreline during peak biomass periods.

Although data from the Virginia Institute of Marine Science (VIMS) has indicated an increase in SAV distribution in recent years due to ongoing restoration and protection practices, creating a campaign geared toward boaters’ behaviors will help encourage and ensure mindful boating practices in our waterways for the future. Coinciding with ShoreRivers’ current SAV monitoring program, the developing behavior change campaign will aim to play a key role in reducing damage to underwater grasses, while also raising awareness and knowledge of their importance for our Eastern Shore rivers.


January 2018 Choptank River News


It’s hard to believe it’s already a new year! When thinking about a New Year’s resolution, I thought—what if just half of the citizens who live around the Choptank River would resolve to do something good for their local waterway? Where would we be if every other household stopped using lawn fertilizers, if at least every other farm planted a winter cover crop, or if every other septic system was maintained routinely? For my New Year’s resolution, I’ve challenged myself to engage more citizens and more communities with the Choptank River than we ever have before and connect them with the diversely valuable resources surrounding the river. It is through experiences like kayaking the river from Greensboro to Denton, hiking through Tuckahoe State Park, or sailing in Oxford and Cambridge that we start to develop an appreciation and a willingness to act and protect what it is we appreciate. Join the Choptank Riverkeeper and all of ShoreRivers staff in a new year of opportunities and engagement with our local waters!

Cambridge Creek Watershed Assessment

ShoreRivers and the Choptank Riverkeeper are excited to release the Cambridge Creek Watershed Assessment and Action Plan. Over the last year, our staff has been busy collecting data, interviewing watershed partners, and identifying and prioritizing projects that can help to systematically restore the water quality in Cambridge Creek. Strategies, recommendations, and over 100 projects have been identified to help reduce nutrient and sediment pollution and protect against insufficient discharge permits. The goal of the assessment is to compliment the work that the City of Cambridge is already doing by engaging watershed partners, businesses, churches, and the whole community in a coordinated effort to improve local water quality. Take a look through the plan and find out how we can work together as a community that deserves clean waterways.

Maryland Environmental Legislative Summit Recap

The 2018 Environmental Summit took place earlier this month, and our Riverkeepers were there taking part in the event and strategizing on this year’s advocacy efforts. To the environmental community, the summit represents the beginning of the Maryland General Assembly’s Legislative Session. This year over 250 citizen advocates, professionals lawmakers, and your four Riverkeepers came together to celebrate and rally over the environmental community’s legislative agenda. Among the top priority bills were the Forest Conservation Act to protect our remaining intact forests; the Styrofoam Ban bill to ban a material that’s been polluting out waterways for long enough; and a bill requiring Maryland to join the US Climate Alliance with other states in a coalition to reduce greenhouse gas emission. As Choptank Riverkeeper, I had the great honor of introducing a number of the speakers at this year’s event including the chair of the Education, Health and Environmental Affairs committee; the executive director of our longstanding partner, the Chesapeake Legal Alliance; the speaker for the Clean Energy Jobs Initiative; and the speakers for the Styrofoam Ban bill – student representatives from the youth-funded organization Baltimore Beyond Plastics.
