Both … Without oxygen, the fishery dies.Fish and crabs swim and sidle away and leave our river. The Severn River Association mission is to provide a healthy and thriving Severn River for present and future generations. They track dissolved oxygen, pH, temperature, salinity and clarity.You can view all this data on the Chesapeake Data Explorer. Preemptive Rainfall Advisory After rainfall of 1/2 inch or more, all Anne Arundel County beaches are under a no swimming/no direct water contact advisory for at least 48 hours due to predicted elevated bacteria levels from rainwater runoff and increased health risks. Culprit: A dirt-bike recreational area that lacks any best management practices to control stormwater runoff.These factors that have created permanent, oxygen-depleted conditions in our river. Quality water; Service you can rely on; Affordable bills; Sustainable finance ; Our commitments; Future plans 2020-2025. All that water made the Severn River less salty, hurting oysters but sparking an explosion of false dark mussels that thrive in fresher water.
The Severn River gets pounded year round by a polluted mix of stormwater runoff that floods the river with nitrogen, phosphorus and sediment contaminants that combine to create algae blooms which then decompose and dilute the river of oxygen.To track how our river responds to this pollution insult, volunteer citizen scientists have joined our fabled Water Quality Crew to create a 41-station network of monitoring stations.Each week (May-October), our WQ Crew and Boat Captains create profiles of the water column in our river and creeks.
This is why the Severn River Association collects weekly data readings to paint a portrait of the water column at 41 locations along the 14-mile Severn River and its 39 creeks and coves.
quality of the water environment. We'll let you know about the many ways you can ensure that future generations will also be able to Treasure The Severn River.Here are some SRA initiatives where we could use your help.
You can keep up to date with news and learn about water quality and Severn Trent Water's services.
In 2020, a 16 week schedule costs $475 and runs from May 27th through September 9th. As rural areas turned suburban and then urban, the Severn lost its ability to bound back from these challenges.
50 Bridge.The photo at left is one of our volunteers, Steve from Annapolis, using a Seechi disk to measure clarity in Lake Ogleton.SRA partners with the Chesapeake Monitoring Cooperative (CMC) to provide technical expertise, ensure quality assurance and collection control procedures for our water quality program and to provide a vehicle for sharing the data collected to the scientific community.All the data collected by our WQ Crew is shared with the scientific community via CMC’s Data Explorer program that tracks water quality for the entire Chesapeake Bay watershed.You can track all this work at the CMC’s Data Explorer website.
Prof. Muller, an Associate Professor of Oceanography at the U. S. Naval Academy, provided the initial training to a small team of citizen scientist volunteers who collected data from 8 stations in the top of the river.The program collects basic water profile information: dissolved oxygen levels, salinity, pH, temperature and clarity. Good healthy levels of oxygen should normally be 5 mg/L or greater to keep our fish, crabs and oysters happy.But we started finding oxygen levels well below this 5 mg/L level. Water levels on Rice Lake and the Lower Trent River are anticipated to increase due to increased inflows from local creeks, the Otonabee River, Crowe River and the forecasted rainfall. For bodies of water that the Department samples, the acceptable level of enterococci bacteria is 104 or fewer bacteria colonies per 100 milliliters of water.
The acceptable level for swimming and other direct water contact is determined by the U.S. Environmental Protection Agency, Maryland Department of the Environment and the Anne Arundel County Department of Health. But in 2019, this dead zone extended from the Narrows to the foot of the Rt.
About Us. It was a bit over 5 square miles, roughly the size of Denton, Md.Add to this mix, fecal bacteria from pets, septic systems and wildlife, mud floods of sediment from uncontrolled construction sites, rapid development, loss of vegetation and tree cover and severe weather events that flood our waters with enormous levels of sediment and nutrient pollution.The river faces a constant challenge from human activities and we’re already feeling the impacts of climate change, rising sea levels, and increased frequency and intensity of storms.
With a team of volunteer citizen scientists who help monitor 41 stations throughout the entire Severn River watershed. It was a windy, rainy year. Oysters can’t swim away, so without oxygen, they suffocate in these conditions.Result: The Environmental Protection Agency declared the Severn River an “impaired” waterway and imposed a “pollution diet” to reduce the flood of pollutants, primarily nitrogen, phosphorous and sediment.How do we track progress? 50 Bridge. Severn River Lake Simcoe water levels are below average, increasing and will continue to … During the summer of 2019, our WQ Crew started noticing very low oxygen levels in the Severn River, and this phenomenon was echoed inside many creeks. Instead, the river suffers from algae blooms, bacterial infestations, sediment and nutrient overloading during every rain event.The picture at left is of silt plume in Luce Creek just after a heavy rain the night before. We visit these stations every week from May through October.Computer modeling can only get to a best-guess of what conditions are like in a waterway.The only way to really know whether we’re making any progress towards improving water quality – especially reducing the scale of the dead zones – is to collect water quality monitoring data from the river itself.This is why the Severn River Association collects weekly data readings to paint a portrait of the water column at 41 locations along the 14-mile Severn River and its 39 creeks and coves.The SRA water quality program was first created under the guidance of Prof. Andrew Muller in 2018. Above is WQ Crew Team leader, Mackenzie, recording the data collected at our Marylanders Grow Oysters restoration reef at the foot of the Rt. The water flows from Lake Couchiching into the lower Severn River and out to Georgian Bay at lock 45 at Port Severn.
