Higher Water Levels on St. Lawrence River to Aid Boat Removal

boat being lifted out of the waterThe water level increase should be minimal in Augusta Township (levels are expected to increase by 27 centimeters or 11 inches in Cardinal) but even a slight increase may assist the removal of larger boats.

On Thanksgiving weekend between 7 p.m. on October 5th and 4 p.m. on October 7th, the outflow at the Moses-Saunders Dam in Cornwall will be reduced. The second weekend will be between October 12th at 7 p.m. and October 14th at 4 p.m.

Please pass along this information to your friends and neighbours.

Drought Conditions Worsen in Augusta Township: September 25, 2018map of South nation conservation low water conditions status

As this update is being prepared, we have received 8mm of rain overnight in the municipality. Late last week, the storms that impacted the Ottawa-Gatineau areas deposited a total of 28mm in Augusta Township.

Despite these events and the forecast of more rain over the next several days, the drought advisory in our municipality has been upgraded from a Level 1 or Minor to a Level 2 or Moderate within South Nation Conservation’s watershed area South Nation Conservation’s Low Water Response Team met on September 21 and recommended the Level 2 situation. The team members, from across the watershed noted algae blooms, fish stranded in pools in dried-up streams and reduced crop yields, as indicators of the current drought conditions. The Rideau Valley Conservation Authority has indicated that the Kemptville Creek sub-watershed is at a Moderate or Level 2 for well over a month. Only a small area along the St. Lawrence River remains a Level 1 or Minor.

Residents, businesses and other industries can help by reducing their water consumption by 20% and limiting non-essential uses.

Please let the office know if you are experiencing any effects from the drought.

Low Water Status Update: September 18, 2018

The North Augusta area received 8mm of rain over the weekend. The weekend prior we received a total of 13mm. Despite the two rainfall events, the north end of Augusta Township remains at a moderate low flow status (Level 2). The Kemptville Creek sub-watershed has flows of 1.3% of normal for this time of the year. Aquatic species will be increasingly stressed as available pools shrink, temperatures rise and oxygen concentrations decline.

The southern end of the municipality remains at a minor or Level 1 status. South Nation Conservation has called a meeting of its Low Water Response Team to discuss the current and long term situation and to determine if the low flow status should be escalated.

We continue to encourage everyone to reduce water consumption wherever they can.

This site will be updated as new information is made available.

Low Water Status Update: August 20, 2018

Despite significant isolated storms in recent weeks, the three conservation authorities (South Nation Conservation, the Rideau Valley Conservation Authority and the Cataraqui Region Conservation Authority) covering Augusta Township have decided to maintain a Minor or Level 1 Low Water Status within their watersheds.

The exception in our area is the Kemptville Creek Subwatershed. It is designated as Moderate or Level 2. Flows in Kemptville Creek have been declining to the point where they are now 4% of the normal historic flow for this time of the year (was at 6% on August 07, 2018). Rain that has fallen on the subwatershed has been absorbed into the ground and retained by wetlands. Beaver activity has created pools that have a negative impact on aquatic species (confined spaces, warmer water and declining oxygen levels).

The long term forecast for the remainder of August and for September still calls for warmer and drier conditions than normal. Alleviating the low water conditions would require regular rainfall over the next weeks and months.

Residents, businesses and industries are encouraged to reduce water consumption wherever they can.

Updates will be provided as warranted.

Water Level for Augusta Township

drying up creek bedAs of 08:00 this morning (August 07, 2018), the North Augusta area had received approximately 35 mm (1.4”) of rain over the long weekend. The Maynard area received 18-20 mm (0.72-0.8mm) over the same period.

Both the Rideau Valley Conservation Authority and South Nation Conservation are maintaining a Minor Severity or Level 1 low water status (both watersheds are extensive and rainfall events will normally vary across both watersheds).

An excellent local example of the differences in water levels can be seen within the Kemptville Creek sub-watershed. Kemptville Creek is currently at 6% of its normal flow for this time of the year. At the same time, the Jock River, just south of Ottawa, was at twice its normal rate of flow for this time of the year (based on last week’s precipitation). In viewing the South Nation River, its flow does not appear to have increased significantly despite the rainfall. The rain we are receiving is entering the ground and nourishing vegetation and crops as opposed to running off in our streams and ditches.

Long range forecasts still indicate warmer and dryer than normal conditions through the rest of the summer and fall. Please continue to practice water conservation wherever you can.

Updates will be provided as conditions warrant.

Conservation Authority moves to a Moderate level of severity

Effective July 19, 2018, the Rideau Valley Conservation Authority (which covers the top 1/3 of Augusta Township, predominately the Kemptville Creek watershed) has moved to a Level 2 low water statement or moderate level of severity. South Nation Conservation are presently still at Level 1.

Sunday, July 22nd‘s rain and precipitation presently forecast for the remaintotally dried up creek bedder of this week will be welcome but is not expected to have a significant impact. Our grass may require mowing but potentially not for long. Longer range forecasts indicate temperatures above normal and precipitation levels below normal throughout the remainder of the summer and into the fall.

At Level 1, water users are asked to voluntarily cut back water consumption by 10%. At Level 2, a further 10% reduction (for a total of 20%) is requested.

In order to help track the severity of this year’s low water event, the municipality would appreciate receiving information from residents in relation to dry wells and crop damage. Our grass, while it may appear dried out, has gone dormant. Given sufficient precipitation, it will readily recover. Please email your comments to emergplan@augusta.ca.

The grass is brown, flowers and vegetables are wilting if not watered regularly and crops are not growing as well as they might be. All are suffering from the hot weather and a lack of precipitation.

Both South Nation Conservation and the Rideau Valley Conservation Authority have issued low water statements which includes all of Augusta Township. Unlike last summer, our precipitation levels over the past three months were 60-76% below normal. The South Nation River, at DeJong Road, is down to a trickle.  Most other watercourses and drainage ditches are dry.

South Nation Conservation, in accordance with the Ontario Low Water Response Program, has declared a Level 1 Low Water Condition. Residents, businesses and other industries throughout the SNC watershed are asked to voluntarily reduce water consumption by 10%. Water consumption can be reduced by limiting non-essential uses (i.e. lawn watering, car washing, etc.).

If we do not receive sufficient precipitation in the foreseeable future, we may see the declaration of a Level 2 which would entail a further reduction in water consumption.
