Water Acquis in the EU
1) The document discusses the status of implementation of EU water policies in member countries. It focuses on the Water Framework Directive and Urban Waste Water Treatment Directive.
2) Based on 2009 data, only 43% of water bodies showed good ecological status, short of the 53% target for 2015. Progress has been modest and more integrated implementation is still needed.
3) Regarding the Urban Waste Water Treatment Directive, collection systems are largely in place but some EU-13 countries still need to meet obligations for secondary/biological treatment, especially in sensitive areas. Compliance in large cities has improved but work remains for sensitive areas.
Anders, Water Rates
The document summarizes Austin Water's financial impacts and response to the Central Texas drought from 2008-2015. It describes how extreme drought conditions led to long-term water restrictions that significantly reduced water demand and caused revenue losses of up to $52 million per year. In response, Austin Water implemented a new financial model with tiered fixed fees, increased the fixed revenue percentage, established a reserve fund, and raised rates gradually to stabilize finances and improve bond ratings. The future outlook has improved now that drought conditions have eased.

TWCA Annual Convention: Water Rights Developments in Other States, Lyn Clancy
This document summarizes several recent court cases related to water law and policy in various western states:
- In California, a court found that the public trust doctrine can protect groundwater connected to navigable waterways from overextraction. Another case supported regulating water use to protect salmon runs.
- Oregon law requires considering impacts to specific fish species when approving new municipal water permits or extensions.
- Washington courts found that new diversions cannot impair existing instream flows without overriding public interest, and that injury to senior water rights is not permitted even for municipalities.
- In Colorado, private diversions for recreational or aesthetic purposes were not considered a beneficial use of water under the prior appropriation system.

Comp Plan 2020 Public Input Summary
The document discusses water resource issues in the Coon Creek Watershed District. It provides background on the district and outlines its mission to manage water resources. Key issues discussed include declining water supply from groundwater and surface water sources. Changing precipitation patterns are exacerbating supply concerns. Demand for water is increasing for uses like drainage and recreation. Flood control and water quality are also indirect demand issues. The document classes water resource issues as serious, deteriorating, or sustainable based on the threat level and availability of management strategies. Input is sought from attendees on resource needs and management expectations going forward.
Sea Level Rise in South Florida
The document summarizes research correlating qualitative observations with quantitative data on sea level rise in Florida Bay. Monthly mean sea level trends from a NOAA gauge station show annual fall flood heights from the 1980s are now average heights, equivalent to a 0.91 foot rise in 100 years. Qualitative observations by local guides also indicate longer flooding durations and more frequent high tide flooding. Climate models project 0.6-4.7 feet of additional sea level rise for the area by 2100. Major impacts are expected to population centers, infrastructure, and coastal development from accelerated sea level rise.
The Rising Cost of Water
The West Harris County Regional Water Authority (WHCRWA) was created in 2001 by the Texas Legislature to facilitate reducing reliance on groundwater and ensuring a long-term supply of surface water for municipal utility districts in its boundaries. The WHCRWA negotiated a surface water contract and has constructed over 50 miles of pipelines and other infrastructure at a cost of over $500 million to meet groundwater reduction mandates of 30% by 2010, 70% by 2020, and 80% by 2030. Water rates have increased over time to fund ongoing construction projects needed to secure water supplies for future demands, though the WHCRWA aims to keep costs as low as possible.

The document proposes a rule change to the Texas Commission on Environmental Quality (TCEQ) to provide incentives for wastewater treatment plants to beneficially reuse treated effluent. Currently, land application permits (TLAP) do not provide credit for reuse, requiring plants to acquire more land than needed. The proposed rule would allow plants to claim a credit toward reducing the required size of disposal fields and ponds based on the volume of effluent that can be reliably reused through contracts. This would help plants expand capacity in a flexible manner without acquiring additional land, encourage water reuse, and reduce costs and permitting hurdles associated with population growth in central Texas.

Indonesia workshop evaluation iwrm 2000 2010-indonesia_sutardi-a_21092011
The document summarizes Indonesia's water resources management from 2000-2010. Key points include:
- Water quality declined from upstream to downstream due to degradation, pollution, and lack of wastewater treatment.
- Floods and droughts increased in frequency and severity, causing more casualties, evacuations, and economic losses.
- Climate change began impacting the country through more extreme weather, sea level rise, and decreased agricultural production.
- The institutional framework for water management involved many levels of government and other stakeholders, but issues remained around regulatory functions, law enforcement, capacity, and conflicts of interest.
Session 2 presentation
This document summarizes the Water Authority's efforts to increase the reliability of the San Diego region's water supply through diversification. It shows that the region relies heavily on imported water supplies, which face uncertainties. To address this, the Authority has pursued a variety of local supply projects including seawater desalination, water transfers, groundwater, and recycled water. Charts depict the region's historical and planned water supply portfolio mix out to 2035 as it diversifies its supplies. The document also discusses drought planning, noting California's variable precipitation and the Authority's approach to coordinating a regional response.
Urbanization and Baseflow Impacts - Evidence-based Water Budget Management an...
Green infrastructure, low impact development practices (LIDs), also called stormwater management best management practices (SWM BMPs), are often proposed to restore water balance functions and mitigate impacts or urbanization on runoff and recharge. One argument is that baseflows are lowered due to reduced infiltration and discharges to watercourses. It is a simple textbook theory.
What does the data show? The following slide presentation was prepared to respond to the Ontario draft LID guidance manual in early 2017 since water balance impacts have been cited as justification for this infrastructure.
Local studies show that baseflows have increased over decades of urbanization, calling into question the need for such measures considering that potential impact has not materialized. As noted in TRCA's Approved Updated Assessment Report under the Clean Water Act, at most gauges there was an upward trend in baseflows which prompted this: "These overall increases to baseflow volumes are contrary to the common thought that increased impervious cover leads to reduced baseflow" - so for those keeping score, data - one, common thought - zero. TMIG also analyzed baseflows in the GTA and noted “The seven-day average consecutive low flow data provides an indication of the observed baseflows within a watercourse, and hence is a suitable measure for determining whether baseflow trends exist in an urbanizing area. The trend analysis identified noticeable baseflow trends in 13 of the 24 recording stations. Of these eight urban and two rural stations exhibited an upward trend, suggesting increasing baseflow.”

This document summarizes a study on the impact of drainage water recycling (DWR) on nutrient and sediment losses from agricultural fields in eastern North Carolina. The study found that storing drainage water in an on-farm reservoir for supplemental irrigation (DWR) significantly reduced nitrogen, phosphorus, and sediment concentrations and loads compared to a non-irrigated control field. Specifically, DWR reduced total nitrogen concentration by 40% and load by 47%. It also reduced total phosphorus concentration by 21% and load by 30%. Sediment concentration was reduced by 86% and load by 87%. The hydraulic retention time in the reservoir was found to be the major factor influencing nutrient and sediment removal efficiency.

- River pollution, urban flooding, and health risks are interconnected issues facing rapidly growing cities. As urban populations and impervious surfaces increase, water quality deteriorates due to inadequate wastewater treatment and increased runoff, while extreme rainfall events exacerbated by climate change raise flooding risks.
- Hydrologic and water quality models were developed to simulate current conditions and project impacts of population growth, climate change, and policy measures in selected cities. Results show that without action, flooding and waterborne diseases will increase substantially by 2030.
- Implementing integrated measures like expanded wastewater treatment, flood control infrastructure, and green infrastructure can significantly reduce flooding and health risks compared to do-nothing scenarios. However, non-structural

The document discusses GTI's water-based life cycle model for analyzing and planning sustainable shale gas development. The model tracks changing water outputs, waste, and infrastructure needs over 30-50 years to identify challenges and solutions. It accounts for variable well drilling and changes in water reuse opportunities over time. The model helps predict issues like increased transportation needs and landfill capacity to support long-term planning and improved environmental performance of shale gas operations.
#13 - Comp Plan - Trends & Implications -continued
The document discusses various demands on and trends affecting mining, recreation, public lands, flood control, groundwater recharge, and water quality in a watershed district. Mining is expected to use alternative water sources and change pumping rates to reduce impacts. Recreation is increasing but management of lands and water remains limited. Public land uses impact water quality and management challenges may rise. Flood control focuses on maintaining existing profiles but climate change could increase atypical floods. Groundwater recharge may become a larger district focus. Water quality faces threats from development and storms, and portions of watersheds lack needed infrastructure.

This inequality is especially critical for Asia, which
has 60% of the world’s population but only 36% of
the world’s water. Water quality in terms of pollutant
loading also is not distributed equally and is related
to the type of use and a country’s level of develop-
ment (Figure 2). Developing countries often have
less capacity to improve water quality and depend
on lower-quality water for a variety of uses, includ-
ing drinking water.
To capture an overall picture of a nation’s water
use, researchers calculate the national water foot-
print; this represents the total volume of freshwater
used to produce the goods and services consumed
by a population and the impact of globalization by
F
or more than a decade, the scientific com-
munity as well as nongovernmental orga-
nizations have sought to raise an alarm
concerning the unsustainable use of the
planet’s available water resources (1). Rising
world populations and consumption are inexorably
increasing human demand for domestic, industrial,
and agricultural water. Population and wealth along
with other global stressors will have a direct and
significant impact on the sustainability goals, tech-
nology selection, and governance strategies that are
related to water quality and quantity.
On a global basis, ~70% of freshwater is currently
used for crop irrigation, ~20% for industrial purpos-
es, and ~10% for domestic purposes (2). However, wa-
ter use varies dramatically from one part of the world
to another. Egypt, for example, uses 98% of its water
for irrigation, leaving only ~27 L/capita-day for do-
mestic use. In contrast, the U.S. uses 40% of its water
for irrigation, and domestic water use exceeds 410 L/
capita-day. In refugee camps in Africa and Asia, resi-
dents may receive only 15 L/capita-day for both con-
sumption and hygiene. For comparison, the World
Health Organization defines reasonable access as
the availability of at least 20 L/capita-day from a
source within 1 km of the user’s dwelling (3).
Although the quantity of water used varies by
region, water is not distributed equally (Figure 1).

accounting for water across the life cycle of imports

water volumes consumed (evaporated) or pollut-
ed per unit of time. In this way, it is similar to the
concept of “virtual” water, because it accounts for
water use associated with consuming agricultural
and industrial imports ...
Efficient Use of Water - Drew Beckwith, Western Resources Associates
Three sources of water are generally cited for to support continued population growth in the West: new diversions from rivers, transfers from agriculture to cities, or reduced use through conservation. Municipal conservation is the cheapest of the three, and often has the least impact on Western rivers.
This presentation describes the potential for conservation to reduce future demands, provide examples of implementation (including rate structures, water loss reduction, and indoor and outdoor best practice programs), and discuss Colorado state-level resources available to develop and implement conservation plans. Important concerns and issues regarding water conservation will also be addressed, including cost to the consumer, water quality, and impacts to return flows.

Crooked lake public input workshop
This document outlines the 2014-2018 management plan public input workshop for Crooked Lake. It discusses the status of the current management plan and identifies key issues from the previous plan around invasive species, water clarity, muck, water quality, garbage, water levels, and implications for the future. Data on trends related to these issues is presented. The document concludes that water quality has improved but invasive species remain a challenge and effects of groundwater on water levels needs continued attention. The local water management district outlines ongoing and planned activities to monitor the lake and watershed and develop new management plans and studies.
2013 winter meeting crooked lake management plan
This document summarizes the management of a shallow lake from 2008 to 2013. Key issues included invasive species, water clarity, muck, water quality/pollution, and water levels. Water quality showed improvements from 2008-2012 in metrics like phosphorus and clarity. Invasive aquatic plants remained a challenge. Future plans included continued monitoring, updating management plans, studying groundwater impacts, and assessing the lake berm.
Obstr hearing only
The Coon Creek Watershed District Board held a hearing to determine if an obstruction in County Ditch 58-6 should be removed. The ditch experiences flooding due to an undersized culvert on Polk Street installed in 1964-1970. Three properties are affected by the flooding. The Board considered inspection reports from 2011 showing flooding, as well as safety and flood damage concerns from the landowners. Engineers recommended replacing the culvert with a longer, larger diameter culvert to reduce flooding and safety issues. Cost estimates were provided and two contractors provided quotes for the work.

2011 Winter Meeting Lake Comp Plan update
The document summarizes the 2011 update to the Crooked Lake Comprehensive Management Plan. It outlines the plan's approach of developing strategies to address issues, implementing solutions, monitoring results, and adapting the management plan. Key issues identified include invasive species, water clarity, muck, nonpoint source pollution, and water levels. The document reviews activities from 2009-2012 to address these problems and questions from the public workshop.
#11 - Comp Plan - Wetland Management
The document discusses trends in wetland loss and implications for management. Over 5,137 acres of wetlands have been lost due to drying of the landscape. An additional 8,375 acres, or 52% of wetlands, have lost hydroperiods classified as temporarily flooded or saturated. This drying is causing organic soils to decompose, invasive species to spread, and upland species to colonize wetland areas. The loss of hydrology and wetland functions implies a probable permanent loss of 52% of wetland stock and potential removal from 60-80% of the county due to land subsidence and hydrophobic soils. Managers can expect more delineation challenges and fewer areas meeting jurisdictional wetland definitions going forward.
#10 - Comp Plan - Wildlife Management
The document summarizes wildlife and fisheries in a watershed district. It found that habitats and populations were generally in good condition, though endangered, threatened, and special concern species continue to increase, concentrated in the eastern portion. It identifies rare plant communities that require awareness of habitat needs for critical species, and habitat management plans may be developed.
#9 Comp Plan Mission & Commitments Review
The Coon Creek Watershed District has statutory and regulatory obligations to administer activities affecting water resources, regulate such activities, plan projects, operate and maintain infrastructure, and inform and educate the public. Its mission is to manage groundwater and surface water, maintain hydrologic balance, prevent property damage, protect water quality, and provide for public safety, enjoyment, and resource preservation and enhancement through programs in administration, development regulation, operations and maintenance, planning, information/education, and research/monitoring. The District carries out its business through budgets, staff, land management, provision of services, contracts, cooperation, and collaborative efforts.
#8- Comp Plan - Water Quality
This document reviews water quality data from 7 studies in the Coon Creek watershed. It found high levels of suspended solids that exceeded standards once, as well as impaired dissolved oxygen levels in Sand Creek. Trend analyses showed impairments for turbidity, total suspended solids, and phosphorus. The lower portion of the watershed lacks infrastructure needed for water quality improvements.
#7 - Comp Plan - Lakes
The document summarizes water quality trends in three lakes - Crooked, Ham, and Netta - located within the Coon Creek Watershed District in Minnesota. It finds that while Crooked Lake has seen significant improvements in water quality from 1983 to 2009, Ham and Netta Lakes have shown no clear trends over the long term for parameters like total phosphorus and chlorophyll-a. Declining water levels pose the biggest threat and risk lower levels that could negatively impact fish and water quality. Water levels are expected to continue dropping with potentially more invasive species issues.
#6 - Comp Plan - Surface Water
This document summarizes information about surface water in the Coon Creek watershed district. It reviews hydrologic budget data and stream flow variation over 100 years. Analysis of rainfall data from 1985, 1999, and 2009 shows that less than 1 inch of rain did not cause much runoff in 1985, the fate of 1 inch of rain needs to be managed now, and water levels increase substantially with each inch of rain currently. Graphs show increasing water levels over time at three locations. The implications are that the lower watershed remains prone to flooding and shows some independence from the rest of the watershed. Increased erosion and water quality issues are expected in the lower watershed going forward.
#2- Comp Plan - Issues input
This document summarizes discussions from a meeting regarding a 2010-2020 comprehensive water management plan. It identifies state and local agencies in attendance and their initial issues and concerns. These include balancing water quantity and quality, challenges from physical resource limitations, and effectively enforcing regulations. The document also outlines projected rule and permit revisions, program requirements, and a proposed implementation schedule for the comprehensive plan.
#4- Comp Plan - Evaporation & Evapotranspiration
This document discusses trends in evapotranspiration and evaporation in the Coon Creek Watershed District over the past decade. It shows that excess precipitation from evapotranspiration and evaporation has decreased based on Thornthwaite and evaporation coefficient models. This decrease in excess precipitation is expected to result in less natural recharge and loss of lakes and wetlands in the watershed district.
#3 - Comp Plan - Climate & Precipitation
The document outlines a plan to update the climate and precipitation chapter of the Coon Creek Watershed District's 2020 Comprehensive Plan. It recommends analyzing updated data sets to bring statistics and trends up to date for the district, reviewing implications of changes in precipitation, and considering increasing volume management requirements to 1.5 inches to address expectations of changes in precipitation volume and support surficial aquifer and water quality management needs.
#1 - Comp Plan 2010–2020 Intro
The 2010-2020 Comprehensive Plan outlines requirements to protect water quality, prevent soil erosion, and reduce pollution over the next decade. It proposes an education program, regulatory inspections, BMP maintenance, and water monitoring. The plan approach involves developing strategies around management, social, and physical factors, then implementing, monitoring, evaluating needs, and using adaptive management over the 10 year period.
#5 - Comp Plan - Groundwater
This document discusses groundwater storage and flux in the Coon Creek Watershed District. It outlines the surficial geology including lake deposits and river terrace deposits. The generalized geology profiles from west to east and in the upper 120 feet are presented. Implications are discussed such as more available groundwater storage, more infiltration, difficulty maintaining surface water resources, and groundwater resources behaving differently. Expectations for management include increased irrigation demand, and increased recreational/aesthetic use concerns.

Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
